Is my POST method correct
//Is my post method correct because google and claude are telling me I must use content type for the json and use .setvalue. I thought that my process was correct because I encode the data to turn into json and then make the request func createTask(_ task: Task) async throws -> Task { if let url = URL(string: "(baseURL)/todos"){ var request = URLRequest(url: url) request.httpMethod = "POST" let encoder = JSONEncoder() do{ let data = try encoder.encode(task) request.httpBody = data let (data, response) = try await URLSession.shared.data(for: request) return task //we want to make encoder and then turn the data into json and put it in body } catch{ throw JSONErrors.encodingFailed } } else{ throw URLError(.badURL) } }

High count of webview content process termination
Our iOS app uses React Native Webview (based on top of WKWebView) to display content. This webview stays in memory throughtout the app's lifecycle. We are observing a high number of webview content process terminations - around 15% of our sessions. (https://aninterestingwebsite.com/documentation/webkit/wknavigationdelegate/webviewwebcontentprocessdidterminate(_:)) What could be the reasons for it? Is there a way to know for sure? Is the 15% of sessions number something that other apps also experience, or should this be lower? Thanks!

header and footer positions shifted in Safari tab settings
Thank you for supporting me. My environment Device: iPhone 15 Pro OS: iOS 26.0 Public Beta (23A5336a) In iOS 26, three types of tabs were added to Safari. Depending on the option, the behavior of the fixed header and footer can be unstable. *Tab settings can be changed in the iOS Settings app under "Apps -> Safari" > "Tabs." The following behavior differs depending on the tab. Compact When scrolling down, the header and footer shift up by a few pixels. A margin is created between the footer and the URL input field. Bottom Behaves the same as "Compact." Top The header is completely hidden below the URL input field at the top of the screen, leaving a margin below the footer. Below is the sample code to check the operation. <!doctype html> <html lang="ja"> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width,initial-scale=1" /> <title>固定ヘッダー/フッター + モーダル</title> <style> :root { --header-h: 56px; --footer-h: 56px; } body { margin: 0; font-family: sans-serif; line-height: 1.6; background: #f9fafb; padding-top: var(--header-h); padding-bottom: var(--footer-h); } header .inner, footer .inner { width: 100%; max-width: var(--max-content-w); padding: 0 16px; display: flex; align-items: center; justify-content: space-between; } header, footer { position: fixed; left: 0; right: 0; display: flex; align-items: center; justify-content: center; z-index: 100; background: #fff; } header { top: 0; height: var(--header-h); border-bottom: 1px solid #ddd; } footer { bottom: 0; height: var(--footer-h); border-top: 1px solid #ddd; } main { padding: 16px; } .btn { padding: 8px 16px; border: 1px solid #2563eb; background: #2563eb; color: #fff; border-radius: 6px; cursor: pointer; } /* モーダル関連 */ .modal { position: fixed; inset: 0; display: none; z-index: 1000; } .modal.is-open { display: block; } .modal__backdrop { position: absolute; inset: 0; background: rgba(0,0,0,0.5); } .modal__panel { position: relative; max-width: 600px; margin: 10% auto; background: #fff; border-radius: 8px; padding: 20px; z-index: 1; } .modal__head { display: flex; justify-content: space-between; align-items: center; margin-bottom: 12px; } .modal__title { margin: 0; font-size: 18px; font-weight: bold; } .modal__close { background: none; border: none; font-size: 20px; cursor: pointer; } </style> </head> <body> <header> <div class="inner"> <h1>デモページ</h1> <button id="openModal" class="btn">モーダルを開く</button> </div> </header> <main class="container" id="main"> <h2>スクロール用の適当なコンテンツ1</h2> <p>ヘッダーとフッターは常に表示されます。モーダルボタンを押すと、画面いっぱいのダイアログが開きます。</p> <!-- ダミーカードを複数 --> <section class="grid"> <div class="card"><strong>カード1</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード2</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード3</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード4</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード5</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード6</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード7</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード8</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード9</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード10</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> </section> </main> <footer> <small>&copy; 2025 Demo</small> </footer> <!-- モーダル --> <div class="modal" id="modal"> <div class="modal__backdrop"></div> <div class="modal__panel"> <div class="modal__head"> <h2 class="modal__title">モーダル</h2> <button class="modal__close" id="closeModal">&times;</button> </div> <p>これは白いビューのモーダルです。背景は黒く半透明で覆われています。</p> </div> </div> <script> const modal = document.getElementById('modal'); const openBtn = document.getElementById('openModal'); const closeBtn = document.getElementById('closeModal'); const backdrop = modal.querySelector('.modal__backdrop'); openBtn.addEventListener('click', () => { modal.classList.add('is-open'); }); function closeModal() { modal.classList.remove('is-open'); } closeBtn.addEventListener('click', closeModal); backdrop.addEventListener('click', closeModal); window.addEventListener('keydown', (e) => { if (e.key === 'Escape' && modal.classList.contains('is-open')) { closeModal(); } }); </script> </body> </html>

Tab onDetached and Tab onAttached web extension events are no longer generated in macOS 15.4 / Safari 18.4
Hello - we have a Mac application that uses a browser extension and the web extension JS APIs to communicate with Safari. As of macOS 15.4 / Safari 18.4 the tab OnAttached and tab onDetached events are no longer received. After some testing we verified that the events were working properly as of macOS 15.3 / Safari 18.3 but appear to have been broken in macOS 15.4. Note a similar issue was reported previously for Safari 17.6 and was fixed in macOS 15.0 (FB14324177). We have made a TestFlight version of our app (Tabby) available to simplify debugging via https://testflight.apple.com/join/Va8Zdv9d. To reproduce the issue: Install the Tabby TestFlight build on macOS 15.4 or 15.4.1 Open Safari, go to Safari settings and select the Extensions tab Enable the Tabby extension and grant permissions to all windows all the time Open a Safari window with at least 3 tabs Note the open window and tabs displayed in Tabby In Safari, perform a tab detach by dragging a tab out of the window Expected behavior Within Safari the detached tab should now be in it’s own window, and via the onDetached event Tabby should update to show the tab in it’s own window AND removed from the original window. Observed Safari fails to send the onDetached event and Tabby will continue to display the detached tab in its original window in addition to the new window. You can also use the repro steps above to observe the onDetached event being received or not by Tabby in the Safari developer console. The same steps but re-attaching the tab to the original window can be used to observe the onAttached event being received or not. We’ve attached two screen recordings to the Feedback ID below, one showing the events working on macOS 15.3, and one showing the events failing to be received on macOS 15.4.1. Note it also fails on macOS 15.4. FEEDBACK ID: FB17367977

Apple Pay Web: Multiple active PPCs for one Merchant ID?
Hi,
 We’re implementing Apple Pay on the Web for a multi-tenant platform via a PSP. The PSP operates multiple HSM/clusters and gave us multiple CSRs, asking us to register all.
Our understanding: a Merchant ID can hold several PPCs over time, but only one is active at once. Questions Is there any supported way to keep more than one PPC active simultaneously for the same Merchant ID? If not, what does Apple recommend for web-only, multi-tenant setups: a single MID with PSP-side decryption & sub-merchant separation, or separate MIDs per brand/region? Any official guidance on PPC rotation and handling many domains for Apple Pay on the Web? links to official docs or prior Apple responses would be appreciated.

On iOS 18.0, when setting a cookie with SameSite=None; Secure, the attribute does not take effect and is automatically converted to SameSite=Lax.
On iPhone 16 running iOS 18.0(Xcode 16.2), cookies configured with SameSite=None; Secure fail to apply correctly—iOS forcibly converts the attribute to SameSite=Lax. As a result, cross-site requests from H5 pages within our app cannot carry the required cookies, causing failures. Can anyone help me on this? Thanks in advance.

WebView permission
Hi, I'm using a webview in Swift, where I load an html file locally. Basically I have an angular project built and loaded directly into my app bundle. The webview requires the use of the camera. I request permissions via and javascript, the pop-up appears, I accept the permissions and the app works correctly. Only that after a certain number of seconds, the permissions are requested again. It's as if the webview doesn't cache the accepted permissions. Is this normal behavior?

Can I use allowFileAccessFromFileURLs to access local html file in my Project and not get appStorereview
We are currently implementing the payment flow, and for handling payment details — including card entry and validation — we are utilizing a WKWebView. The webview securely loads the payment provider’s page, ensuring sensitive information such as card numbers are entered and validated directly within the web context. I’d like to clarify that this change has not yet been released to Production. As part of a feature enhancement to our existing payment flow, we are transitioning to a new payment vendor, SnapPay. While trying to load the SnapPay URL embedded within an iFrame in our iOS app, I observed the following error in the Xcode console. While this error may be generic, I wanted to highlight it: 825a18 - [pageProxyID=7, webPageID=8, PID=67346] WebPageProxy::didFailLoadForFrame: frameID=24, isMainFrame=0, domain=NSURLErrorDomain, code=-999 Upon investigating, we compared the headers from our existing payment URL and SnapPay's URL, and found that SnapPay includes the following Content-Security-Policy (CSP) header: Content-Security-Policy: frame-ancestors ... "Content-Security-Policy" value="default-src 'self'; script-src 'self' https://hcaptcha.com https://.hcaptcha.com https://code.jquery.com https://www.gstatic.com https://code.jquery.com/jquery-3.3.1.min.js https://test.lightbox.cardx.com/v1/lightbox.min.js https://www.ssa.gov/accessibility/andi/ https://c.evidon.com 'unsafe-inline' 'unsafe-eval'; style-src 'self' https://hcaptcha.com https://.hcaptcha.com https://fonts.googleapis.com/css https://stage.snappayglobal.com/Resource/ https://www.ssa.gov/accessibility/andi/andi.css 'unsafe-inline'; img-src 'self' data: https:; font-src 'self' *.googleapis.com *.gstatic.com ; connect-src 'self' https://demo1.cditechnology.com https:; form-action https://hcaptcha.com https: 'self' *.ipg-online.com secure.bluepay.com https://test.api.lightbox.cardx.com https://3ds-acs.test.modirum.com/ https://demo1.cditechnology.com/; frame-ancestors https://snappaydirect-perf.fiserv.com 'self' file: https: http; frame-src .snappayglobal.com 'self' https://hcaptcha.com https://.hcaptcha.com https: https://www.google.com .ipg-online.com secure.bluepay.com https://.cardconnect.com https://test.api.lightbox.cardx.com/ https://test.lightbox.cardx.com https://paywithcardx.com/payment/auth.cgi securepayments.cardpointe.com *.cardpointe.com https://3ds-acs.test.modirum.com/ https://www.yokohamatire.com http://uat1-txt.ad.portal.texas.gov https://uat1-txt.ad.portal.texas.gov " After multiple working sessions with the SnapPay team, we were able to confirm that when they disable CSP or remove the frame-ancestors directive, the iFrame loads successfully within our app. However, SnapPay cannot change on their CSP. To enable the iFrame to load in the iOS app, we added the following line of code: webView.configuration.preferences.setValue(true, forKey: "allowFileAccessFromFileURLs"). This resolved the issue with loading the iFrame. Note: the file being loaded is a local .html file,. Before submitting this update to the App Store, I’d like to confirm whether this usage of allowFileAccessFromFileURLs is acceptable for App Store review. I wanted to confirm that with this change is there a security concern for WKWebview?

HTML problem at Safari on iPadOS 18.2 or after version
We confirmed a problem at Safari on iPadOS 18.2 or after version. For confirmation, we made a HTML document (see below HTML1) what include ‘method="POST" target="_blank"’ and tested the form however server received GET method and there is no parameter, server did not receive “id” parameter. We confirmed that fact in captured packet and log file that on the server. HTML1: We also made another HTML document (see below HTML2) what include submit button, but the server received GET method as above. HTML2: And we also confirmed that it behaves differently depending on the network environment. If the form targets a name that does not exist (ex. target=” A12345”), behaves differently http or https. http: Safari opened new tag, but the server received GET method. Normally, Safari open new tag and the server receive POST method. https: Safari opened new tag, and the server received POST method. It is normally. If the form targets ‘_blank’, the server received GET method on http or https both. We think Safari change the method POST to GET and delete parameters. It is not conformed to the HTML specification if is that true. We confirmed it was not happened at Safari on iPadOS 17.4, and Windows PC (Edge, Chrome). The method what the server received is POST. We find same problem in Apple Support Community (see below URL). https://discussionsjapan.apple.com/thread/255987615 (Described in Japanese) Is it a bug in Safari on iPadOS 18.2 or after version? Do you have plan to fix? Or if fixed the bug, when do you release fixed version.

SafariDomains Per App VPN Profile Error on iOS 26.0
iOS 26 (from beta 1 to beta 2) We have a VPN app that installs a per-app VPN profile with SafariDomains to filter Safari network traffic. This setup works as expected on iOS versions lower than 26.0. See here more details on SafariDomains: https://aninterestingwebsite.com/business/documentation/Configuration-Profile-Reference.pdf On iOS 26, all SafariDomains configured to go through the per-app VPN result in the following error: "Safari can’t open the page. The error was: Unknown Error" Additional Details: Only SafariDomains encounter this error. Other managed apps traffic through the per-app VPN works correctly. Steps to Reproduce: Install the VPN app with a per-app VPN profile. Configure SafariDomains with any URL (e.g., example.com). Open Safari and navigate to the configured URL. Example Configuration: We tested with a simple example by adding only one URL to SafariDomains (example.com). Logs from the console were captured at the moment Safari opened and encountered the error. safari_google2.txt Has anyone else encountered this issue on iOS 26? Any insights or solutions would be greatly appreciated. Thank you!

Install Safari Extension fails with "Unable to download App" and "Operation not permitted" in log
We have a Safari extension that's been up on the App Store for about 18 months with no apparent issues. This week, however, while working on an update, we uninstalled the production version on our test machines and installed a developer version. When we had some issues, we tried to go back to the production version downloaded from the App Store, but we get an pop saying "Unable to download App." In the log, the most obviously relevant error is 'Operation not permitted'. This occurs on several machines and different logins on those machines in both norma and safe modes. However, on another machine that never had one installed, we could still install the app from the app store, so I suspect there is something left behind that needs to be removed, but I don't know what. FWIW, I see the download directory getting created under /Applications, but it is promptly removed when the failure popup appears. Any suggestions?

Safari Extension Error: “Non-persistent background content cannot listen to webRequest events.” after macOS 15.4 / Safari 18.4 Update We’re seeing the following error in the Safari Extensions tab after updating to macOS 15.4 and Safari 18.4: “Non-persistent background content cannot listen to webRequest events.” This error did not appear prior to the update, and we haven’t found any official documentation stating that webRequest API is no longer supported in Safari. In our extension (Manifest V3), we are using the webRequest.onHeadersReceived callback to intercept response headers and read updated cookies. While the functionality itself still works as expected. we’re able to access the response headers and this error is now shown in the Extension settings page. We are not seeing this issue in other browsers (Chrome, Firefox) using the same Manifest V3 setup. Is there any plan to deprecate webRequest support in Manifest V3 for Safari? We’d appreciate any clarification or guidance on how to handle this going forward.

Is my POST method correct
//Is my post method correct because google and claude are telling me I must use content type for the json and use .setvalue. I thought that my process was correct because I encode the data to turn into json and then make the request func createTask(_ task: Task) async throws -> Task { if let url = URL(string: "(baseURL)/todos"){ var request = URLRequest(url: url) request.httpMethod = "POST" let encoder = JSONEncoder() do{ let data = try encoder.encode(task) request.httpBody = data let (data, response) = try await URLSession.shared.data(for: request) return task //we want to make encoder and then turn the data into json and put it in body } catch{ throw JSONErrors.encodingFailed } } else{ throw URLError(.badURL) } }

Accessing Extension Resources from Content scripts
In a Safari Web Extension using Manifest V3, how can a content script access an HTML file that is bundled with the extension (e.g., to inject it as an iframe)? Safari's CSP seem to prevent the use of browser.runtime.getURL() in the MAIN world — is there a recommended way to load such resources securely?

High count of webview content process termination
Our iOS app uses React Native Webview (based on top of WKWebView) to display content. This webview stays in memory throughtout the app's lifecycle. We are observing a high number of webview content process terminations - around 15% of our sessions. (https://aninterestingwebsite.com/documentation/webkit/wknavigationdelegate/webviewwebcontentprocessdidterminate(_:)) What could be the reasons for it? Is there a way to know for sure? Is the 15% of sessions number something that other apps also experience, or should this be lower? Thanks!

header and footer positions shifted in Safari tab settings
Thank you for supporting me. My environment Device: iPhone 15 Pro OS: iOS 26.0 Public Beta (23A5336a) In iOS 26, three types of tabs were added to Safari. Depending on the option, the behavior of the fixed header and footer can be unstable. *Tab settings can be changed in the iOS Settings app under "Apps -> Safari" > "Tabs." The following behavior differs depending on the tab. Compact When scrolling down, the header and footer shift up by a few pixels. A margin is created between the footer and the URL input field. Bottom Behaves the same as "Compact." Top The header is completely hidden below the URL input field at the top of the screen, leaving a margin below the footer. Below is the sample code to check the operation. <!doctype html> <html lang="ja"> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width,initial-scale=1" /> <title>固定ヘッダー/フッター + モーダル</title> <style> :root { --header-h: 56px; --footer-h: 56px; } body { margin: 0; font-family: sans-serif; line-height: 1.6; background: #f9fafb; padding-top: var(--header-h); padding-bottom: var(--footer-h); } header .inner, footer .inner { width: 100%; max-width: var(--max-content-w); padding: 0 16px; display: flex; align-items: center; justify-content: space-between; } header, footer { position: fixed; left: 0; right: 0; display: flex; align-items: center; justify-content: center; z-index: 100; background: #fff; } header { top: 0; height: var(--header-h); border-bottom: 1px solid #ddd; } footer { bottom: 0; height: var(--footer-h); border-top: 1px solid #ddd; } main { padding: 16px; } .btn { padding: 8px 16px; border: 1px solid #2563eb; background: #2563eb; color: #fff; border-radius: 6px; cursor: pointer; } /* モーダル関連 */ .modal { position: fixed; inset: 0; display: none; z-index: 1000; } .modal.is-open { display: block; } .modal__backdrop { position: absolute; inset: 0; background: rgba(0,0,0,0.5); } .modal__panel { position: relative; max-width: 600px; margin: 10% auto; background: #fff; border-radius: 8px; padding: 20px; z-index: 1; } .modal__head { display: flex; justify-content: space-between; align-items: center; margin-bottom: 12px; } .modal__title { margin: 0; font-size: 18px; font-weight: bold; } .modal__close { background: none; border: none; font-size: 20px; cursor: pointer; } </style> </head> <body> <header> <div class="inner"> <h1>デモページ</h1> <button id="openModal" class="btn">モーダルを開く</button> </div> </header> <main class="container" id="main"> <h2>スクロール用の適当なコンテンツ1</h2> <p>ヘッダーとフッターは常に表示されます。モーダルボタンを押すと、画面いっぱいのダイアログが開きます。</p> <!-- ダミーカードを複数 --> <section class="grid"> <div class="card"><strong>カード1</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード2</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード3</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード4</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード5</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード6</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード7</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード8</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード9</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> <div class="card"><strong>カード10</strong><p>適当なテキスト。適当なテキスト。適当なテキスト。</p></div> </section> </main> <footer> <small>&copy; 2025 Demo</small> </footer> <!-- モーダル --> <div class="modal" id="modal"> <div class="modal__backdrop"></div> <div class="modal__panel"> <div class="modal__head"> <h2 class="modal__title">モーダル</h2> <button class="modal__close" id="closeModal">&times;</button> </div> <p>これは白いビューのモーダルです。背景は黒く半透明で覆われています。</p> </div> </div> <script> const modal = document.getElementById('modal'); const openBtn = document.getElementById('openModal'); const closeBtn = document.getElementById('closeModal'); const backdrop = modal.querySelector('.modal__backdrop'); openBtn.addEventListener('click', () => { modal.classList.add('is-open'); }); function closeModal() { modal.classList.remove('is-open'); } closeBtn.addEventListener('click', closeModal); backdrop.addEventListener('click', closeModal); window.addEventListener('keydown', (e) => { if (e.key === 'Escape' && modal.classList.contains('is-open')) { closeModal(); } }); </script> </body> </html>

Tab onDetached and Tab onAttached web extension events are no longer generated in macOS 15.4 / Safari 18.4
Hello - we have a Mac application that uses a browser extension and the web extension JS APIs to communicate with Safari. As of macOS 15.4 / Safari 18.4 the tab OnAttached and tab onDetached events are no longer received. After some testing we verified that the events were working properly as of macOS 15.3 / Safari 18.3 but appear to have been broken in macOS 15.4. Note a similar issue was reported previously for Safari 17.6 and was fixed in macOS 15.0 (FB14324177). We have made a TestFlight version of our app (Tabby) available to simplify debugging via https://testflight.apple.com/join/Va8Zdv9d. To reproduce the issue: Install the Tabby TestFlight build on macOS 15.4 or 15.4.1 Open Safari, go to Safari settings and select the Extensions tab Enable the Tabby extension and grant permissions to all windows all the time Open a Safari window with at least 3 tabs Note the open window and tabs displayed in Tabby In Safari, perform a tab detach by dragging a tab out of the window Expected behavior Within Safari the detached tab should now be in it’s own window, and via the onDetached event Tabby should update to show the tab in it’s own window AND removed from the original window. Observed Safari fails to send the onDetached event and Tabby will continue to display the detached tab in its original window in addition to the new window. You can also use the repro steps above to observe the onDetached event being received or not by Tabby in the Safari developer console. The same steps but re-attaching the tab to the original window can be used to observe the onAttached event being received or not. We’ve attached two screen recordings to the Feedback ID below, one showing the events working on macOS 15.3, and one showing the events failing to be received on macOS 15.4.1. Note it also fails on macOS 15.4. FEEDBACK ID: FB17367977

Apple Pay Web: Multiple active PPCs for one Merchant ID?
Hi,
 We’re implementing Apple Pay on the Web for a multi-tenant platform via a PSP. The PSP operates multiple HSM/clusters and gave us multiple CSRs, asking us to register all.
Our understanding: a Merchant ID can hold several PPCs over time, but only one is active at once. Questions Is there any supported way to keep more than one PPC active simultaneously for the same Merchant ID? If not, what does Apple recommend for web-only, multi-tenant setups: a single MID with PSP-side decryption & sub-merchant separation, or separate MIDs per brand/region? Any official guidance on PPC rotation and handling many domains for Apple Pay on the Web? links to official docs or prior Apple responses would be appreciated.

WKWebView in full screen shows black instead of webpage on macOS 26 beta
As you see in the image, when I fullscreen in WKWebView, it shows black instead of the webpage in full screen. It works fine in Sequoia. It has happened to me since beta 1, but I post it now, because we’re in beta 8 and it’s not fixed. What’s going on? Can somebody tell me if they have the same issue?

On iOS 18.0, when setting a cookie with SameSite=None; Secure, the attribute does not take effect and is automatically converted to SameSite=Lax.
On iPhone 16 running iOS 18.0(Xcode 16.2), cookies configured with SameSite=None; Secure fail to apply correctly—iOS forcibly converts the attribute to SameSite=Lax. As a result, cross-site requests from H5 pages within our app cannot carry the required cookies, causing failures. Can anyone help me on this? Thanks in advance.

WebView permission
Hi, I'm using a webview in Swift, where I load an html file locally. Basically I have an angular project built and loaded directly into my app bundle. The webview requires the use of the camera. I request permissions via and javascript, the pop-up appears, I accept the permissions and the app works correctly. Only that after a certain number of seconds, the permissions are requested again. It's as if the webview doesn't cache the accepted permissions. Is this normal behavior?

Can I use allowFileAccessFromFileURLs to access local html file in my Project and not get appStorereview
We are currently implementing the payment flow, and for handling payment details — including card entry and validation — we are utilizing a WKWebView. The webview securely loads the payment provider’s page, ensuring sensitive information such as card numbers are entered and validated directly within the web context. I’d like to clarify that this change has not yet been released to Production. As part of a feature enhancement to our existing payment flow, we are transitioning to a new payment vendor, SnapPay. While trying to load the SnapPay URL embedded within an iFrame in our iOS app, I observed the following error in the Xcode console. While this error may be generic, I wanted to highlight it: 825a18 - [pageProxyID=7, webPageID=8, PID=67346] WebPageProxy::didFailLoadForFrame: frameID=24, isMainFrame=0, domain=NSURLErrorDomain, code=-999 Upon investigating, we compared the headers from our existing payment URL and SnapPay's URL, and found that SnapPay includes the following Content-Security-Policy (CSP) header: Content-Security-Policy: frame-ancestors ... "Content-Security-Policy" value="default-src 'self'; script-src 'self' https://hcaptcha.com https://.hcaptcha.com https://code.jquery.com https://www.gstatic.com https://code.jquery.com/jquery-3.3.1.min.js https://test.lightbox.cardx.com/v1/lightbox.min.js https://www.ssa.gov/accessibility/andi/ https://c.evidon.com 'unsafe-inline' 'unsafe-eval'; style-src 'self' https://hcaptcha.com https://.hcaptcha.com https://fonts.googleapis.com/css https://stage.snappayglobal.com/Resource/ https://www.ssa.gov/accessibility/andi/andi.css 'unsafe-inline'; img-src 'self' data: https:; font-src 'self' *.googleapis.com *.gstatic.com ; connect-src 'self' https://demo1.cditechnology.com https:; form-action https://hcaptcha.com https: 'self' *.ipg-online.com secure.bluepay.com https://test.api.lightbox.cardx.com https://3ds-acs.test.modirum.com/ https://demo1.cditechnology.com/; frame-ancestors https://snappaydirect-perf.fiserv.com 'self' file: https: http; frame-src .snappayglobal.com 'self' https://hcaptcha.com https://.hcaptcha.com https: https://www.google.com .ipg-online.com secure.bluepay.com https://.cardconnect.com https://test.api.lightbox.cardx.com/ https://test.lightbox.cardx.com https://paywithcardx.com/payment/auth.cgi securepayments.cardpointe.com *.cardpointe.com https://3ds-acs.test.modirum.com/ https://www.yokohamatire.com http://uat1-txt.ad.portal.texas.gov https://uat1-txt.ad.portal.texas.gov " After multiple working sessions with the SnapPay team, we were able to confirm that when they disable CSP or remove the frame-ancestors directive, the iFrame loads successfully within our app. However, SnapPay cannot change on their CSP. To enable the iFrame to load in the iOS app, we added the following line of code: webView.configuration.preferences.setValue(true, forKey: "allowFileAccessFromFileURLs"). This resolved the issue with loading the iFrame. Note: the file being loaded is a local .html file,. Before submitting this update to the App Store, I’d like to confirm whether this usage of allowFileAccessFromFileURLs is acceptable for App Store review. I wanted to confirm that with this change is there a security concern for WKWebview?

HTML problem at Safari on iPadOS 18.2 or after version
We confirmed a problem at Safari on iPadOS 18.2 or after version. For confirmation, we made a HTML document (see below HTML1) what include ‘method="POST" target="_blank"’ and tested the form however server received GET method and there is no parameter, server did not receive “id” parameter. We confirmed that fact in captured packet and log file that on the server. HTML1: We also made another HTML document (see below HTML2) what include submit button, but the server received GET method as above. HTML2: And we also confirmed that it behaves differently depending on the network environment. If the form targets a name that does not exist (ex. target=” A12345”), behaves differently http or https. http: Safari opened new tag, but the server received GET method. Normally, Safari open new tag and the server receive POST method. https: Safari opened new tag, and the server received POST method. It is normally. If the form targets ‘_blank’, the server received GET method on http or https both. We think Safari change the method POST to GET and delete parameters. It is not conformed to the HTML specification if is that true. We confirmed it was not happened at Safari on iPadOS 17.4, and Windows PC (Edge, Chrome). The method what the server received is POST. We find same problem in Apple Support Community (see below URL). https://discussionsjapan.apple.com/thread/255987615 (Described in Japanese) Is it a bug in Safari on iPadOS 18.2 or after version? Do you have plan to fix? Or if fixed the bug, when do you release fixed version.

SafariDomains Per App VPN Profile Error on iOS 26.0
iOS 26 (from beta 1 to beta 2) We have a VPN app that installs a per-app VPN profile with SafariDomains to filter Safari network traffic. This setup works as expected on iOS versions lower than 26.0. See here more details on SafariDomains: https://aninterestingwebsite.com/business/documentation/Configuration-Profile-Reference.pdf On iOS 26, all SafariDomains configured to go through the per-app VPN result in the following error: "Safari can’t open the page. The error was: Unknown Error" Additional Details: Only SafariDomains encounter this error. Other managed apps traffic through the per-app VPN works correctly. Steps to Reproduce: Install the VPN app with a per-app VPN profile. Configure SafariDomains with any URL (e.g., example.com). Open Safari and navigate to the configured URL. Example Configuration: We tested with a simple example by adding only one URL to SafariDomains (example.com). Logs from the console were captured at the moment Safari opened and encountered the error. safari_google2.txt Has anyone else encountered this issue on iOS 26? Any insights or solutions would be greatly appreciated. Thank you!

Install Safari Extension fails with "Unable to download App" and "Operation not permitted" in log
We have a Safari extension that's been up on the App Store for about 18 months with no apparent issues. This week, however, while working on an update, we uninstalled the production version on our test machines and installed a developer version. When we had some issues, we tried to go back to the production version downloaded from the App Store, but we get an pop saying "Unable to download App." In the log, the most obviously relevant error is 'Operation not permitted'. This occurs on several machines and different logins on those machines in both norma and safe modes. However, on another machine that never had one installed, we could still install the app from the app store, so I suspect there is something left behind that needs to be removed, but I don't know what. FWIW, I see the download directory getting created under /Applications, but it is promptly removed when the failure popup appears. Any suggestions?

Safari Extension Error: “Non-persistent background content cannot listen to webRequest events.” after macOS 15.4 / Safari 18.4 Update
Safari Extension Error: “Non-persistent background content cannot listen to webRequest events.” after macOS 15.4 / Safari 18.4 Update We’re seeing the following error in the Safari Extensions tab after updating to macOS 15.4 and Safari 18.4: “Non-persistent background content cannot listen to webRequest events.” This error did not appear prior to the update, and we haven’t found any official documentation stating that webRequest API is no longer supported in Safari. In our extension (Manifest V3), we are using the webRequest.onHeadersReceived callback to intercept response headers and read updated cookies. While the functionality itself still works as expected. we’re able to access the response headers and this error is now shown in the Extension settings page. We are not seeing this issue in other browsers (Chrome, Firefox) using the same Manifest V3 setup. Is there any plan to deprecate webRequest support in Manifest V3 for Safari? We’d appreciate any clarification or guidance on how to handle this going forward.
