Session cookie issue in Apple's Webkit
Dears, We are facing some issue in ios 18.4.1. Recently some of our end users who updated their ios devices to 18.4.1 have experienced random 403 errors in runtime. as per our analysis, We identified that these errors are associated with "CSRF token mismatch". After successful login, the user's CSRF token is causing issue and it was changed in runtime, this causes the cookie mismatch, and the users is getting 403 errors, and the user session is getting invalid suddenly. let me know if anyone facing the same issue in ios 18.4.1 and let me know Is there any workaround for this issue. Thanks.

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.

Handling input type=date on iOS
I created a form field using: On Safari and Chrome desktop, it behaves as expected. Safari shows the current date in grey by default, and Chrome displays a format hint like dd.mm.yyyy, which is perfectly fine. On iOS, however, the field appears completely blank. I understand that the placeholder attribute is not part of the iOS date input behavior, which is technically fine. Still, it would be helpful if developers had the option to define a default display value. In the past, browsers prefilled date inputs, but many developers objected because they needed the field to be empty by default. I have searched extensively and tried several AI tools, and everywhere it says that this cannot be changed. Am I missing something, or is there any way to display a placeholder, the current date, or some kind of visual hint in iOS Safari? Right now, the empty field creates poor UX because users may overlook it. Since the field is required, this can easily lead to validation errors and additional friction. As a workaround, I used a CSS hack with input[type="date"]::before and a content attribute. I also added JavaScript to toggle a pseudo-placeholder value specifically for iOS. Is there a cleaner solution that avoids this workaround? Thanks in advance for your guidance.

TLS re-negotiation fails with ios18.4
I'm running apache with following configuration. /cc require TLS client certificate / not require TLS client certificate Starting with ios 18.4, accessing /cc after / fails with following error: AH02261: Re-negotiation handshake failed, referer: https://www.example.com/... SSL Library Error: error:1417C0C7:SSL routines:tls_process_client_certificate:peer did not return a certificate -- No CAs known to server for verification? It seems like ios 18.4 does not support TLS re-negotiation. (It worked with ios 18.3 and before) Is this an expected behavior or a bug?

iOS share extension cannot open app from Chrome
Our UI-less share extension (com.apple.services) appears in Safari and Chrome. We raise a popup "Open in (app)..." via the Action.js script document.location.href = urlScheme://... in Safari. However, in Chrome, while our extension executes, parses the URL item attachment from Chrome, it never triggers that popup or opens our app. How can a UI-less share extension open our app from Chrome? Is the accepted practice, despite guidelines, turning the com.apple.ui-services view controller invisible and auto-openURLing? Several apps on the store appear to do this, immediately popping their app without any confirmation dialog or UI in both Safari and Chrome. https://stackoverflow.com/a/79369242

HELP!Apple Pay Web application cannot pay due to the bottom rotation issue
I built a web application using the Apple Pay on the Web Interactive Demo with the Payment Request API, but encountered a few issues: The initiated web Apple Pay interface shows a spinning circle at the bottom and cannot proceed with payment(Bottom display:正在处理). What could be causing this? How to set up sandbox testing for payments? How to asynchronously and synchronously retrieve payment results (backend code to fetch payment results)? The demo only shows frontend code using await response.complete("success"); for retrieving payment results my demo URL: https://shop.wowseer.com/rsolomakhin/pr/applepay/

Folder-level image access permissions for browser-only web apps in iOS Safari
We are developing a mobile-first, browser-only web application that requires users to upload 20–200 images stored inside a single folder (for example, a merchant product directory). On iOS Safari: window.showDirectoryPicker() is not supported. is not supported. File System Access API is not available. Users must manually multi-select images from the Photos picker. This creates significant friction for bulk upload workflows. We are NOT requesting unrestricted file system access. We are asking whether a privacy-preserving, user-granted folder-scoped permission model is being considered for web applications. For example: User explicitly selects a folder. The web app receives scoped access only to that selected folder. Access is session-bound and revocable. No background or global storage access is required. Questions: Is folder-level access for web apps being considered for iOS Safari? Does installing a PWA provide any enhanced file access capability? Are there recommended best practices for handling bulk image uploads in browser-only iOS applications? Is there any roadmap alignment with the File System Access API standard? Our goal is to remain browser-only and maintain strict user privacy while improving usability for high-volume image workflows. Any clarification on intended platform direction would be appreciated.

The first four tab bars of Safari are hidden
There is no problem with the content display of each tab, but the tab bar is completely buggy. If you open 5 or more tabs and browse tabs after the 5, the first 4 tab bars will be completely blacked out, and you don't even know how many tabs you have. If you click on the place where the tab title probably exists, the tab is displayed as if the partial display of the tab bar has been restored. There is no problem with content display. But because it is unclear what tab is open, the browsing experience is at its lowest. If you switch to the tab after the 5th, the first 4 will return to the blackout state again. Of course, it is the latest software configuration at the moment. There is no shortage of memory at 24GB. I recently started developing a Safari extension with AppExtension, but is that due to it?

Analysis of issues on Safari with liquid glass
Hello, As previous reports have already shown, there seems to be a few issues on the latest version of Safari, mainly around: Modals taking up the full viewport Elements positioned at the bottom of the screen This also seems to affect the modals on apple.com/iphone. I've recently done an analysis of what can and can't be done in code to work with the new liquid glass UI and thought I'd share my findings here. The full write up, along with screenshots and the demos I used are available in this repository: https://github.com/stevenocchipinti/liquid-glass-spike A brief summary of the findings: The conditions for a fullscreen modal overlay element to cover the entire screen with a position: fixed; seems to be: The background must be semi-transparent Solid colours, linear-gradients, etc. don't work The container must be empty This also means the standard and ::backdrop don't seem to work. The conditions for a bottom sheet to cover the entire screen, including the area around the Safari toolbar seems to be: The element must be positioned within 3px from the bottom of the viewport The height must be within a certain threshold If I've missed anything, please let me know. It would be really nice to have some official documentation on these issues to explain to developers how to do this properly.

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?

Is Picture in Picture supported for WebRTC / WebView video on iOS (outside app)?
Hello, I am implementing video calling on iOS and need to support Picture in Picture (PiP) behavior similar to FaceTime or WhatsApp. What works Audio continues correctly in background CallKit UI works as expected Video works correctly while the app is in the foreground What I’m trying to achieve When the user presses the Home button or switches apps, I want to show a system Picture in Picture window (floating video outside the app). Current setup Video is rendered via WebRTC The video is displayed inside a WKWebView (HTML / JavaScript) PiP works only while the app is foregrounded When the app backgrounds, the video disappears (only audio remains) Questions Does iOS support system Picture in Picture for: WebRTC video WKWebView / HTML video 2 Is AVPictureInPictureController limited only to: AVPlayerLayer AVSampleBufferDisplayLayer 3 If PiP requires native rendering: Is it mandatory to render WebRTC frames natively using AVSampleBufferDisplayLayer? Is PiP explicitly unsupported for WebView / HTML video? 📌 Clarification Apps like FaceTime and WhatsApp are able to show PiP outside the app. I want to understand whether this behavior is achievable only with native video pipelines, or if WebView-based video is fundamentally restricted by iOS. Any official clarification or documentation reference would be appreciated. Thank you.

Inquiry Regarding Vertical Writing Mode Caret Issues in Safari on iOS
Dear Apple Developer Support, We are currently developing a system that requires the ability to edit Japanese vertical text within the Safari browser on iPhone. During our investigation, we encountered an issue that matches the following WebKit bug: 283620 – Caret Positioning Issues in Vertical Writing Mode We understand that this issue is being addressed in the following pull request: https://github.com/WebKit/WebKit/pull/39939 However, it appears that a complete fix has not yet been implemented. Given this situation, we would like to confirm the following: Is there any known workaround for this issue in iOS 17.5 or iOS 18.5 (the latest versions as of now)? If a workaround exists, could you please provide details? If not, could you share the expected timeline for a full resolution of this issue? Although this appears to be an open-source WebKit issue, we are reaching out to Apple because WebKit is tightly integrated with iOS and Safari, and ultimately delivered as part of the iPhone experience. Thank you very much for your support. Best regards, Takao Kurabayashi

The top of the body pages on my website is cut off on ios
Hello, When I view my website (lasaluade) on iphone or ipad the top of my page bodies are cut off (3-4 first lines). However, on PC, Mac or Android everything is OK (see screenshots). For the record, I built this site with Wordpress and Divi Builder, and I've the same result on Safari and Chrome. Not being a developer, I don't know where to look (I just think it's iOS-related). Have you already had this problem? Do you have any ideas? Thanks for your help!

Safari Flags My Rebuilt Site as Deceptive — Need Review / Whitelisting
Hi Apple Devs & WebKit Team, We operate https://excnum.com — a personal website currently under reconstruction. It's HTTPS-secure, hosted on a clean VPS, and now features a simple placeholder page with no active forms, scripts, or external redirects. However, Safari on both iOS and macOS is flagging it as a “deceptive website”, blocking all access. This warning appears even though: The site uses a valid SSL certificate via Cloudflare There are no redirects, tracking scripts, or dynamic code We serve a static landing page (“under maintenance”) with zero interaction No malware, phishing, or obfuscation exists — verified with multiple tools A review request has already been submitted at: https://websitereview.apple.com We believe the site may have been blacklisted previously under past ownership or prior configurations. It has since been completely restructured and cleared, but the Safari warning persists. This false flag is harming visibility and trust for an otherwise neutral website. Any advice on how to expedite re-evaluation or request a manual delisting from the deceptive site list would be much appreciated. Thank you! — Alex Admin, EXCNUM.COM

Analysis of issues on Safari with liquid glass
Hello, As previous reports have already shown, there seems to be a few issues on the latest version of Safari, mainly around: Modals taking up the full viewport Elements positioned at the bottom of the screen This also seems to affect the modals on apple.com/iphone. I've recently done an analysis of what can and can't be done in code to work with the new liquid glass UI and thought I'd share my findings here. The full write up, along with screenshots and the demos I used are available in this repository: https://github.com/stevenocchipinti/liquid-glass-spike A brief summary of the findings: The conditions for a fullscreen modal overlay element to cover the entire screen with a position: fixed; seems to be: The background must be semi-transparent Solid colours, linear-gradients, etc. don't work The container must be empty This also means the standard and ::backdrop don't seem to work. The conditions for a bottom sheet to cover the entire screen, including the area around the Safari toolbar seems to be: The element must be positioned within 3px from the bottom of the viewport The height must be within a certain threshold If I've missed anything, please let me know. It would be really nice to have some official documentation on these issues to explain to developers how to do this properly.

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?

Is Picture in Picture supported for WebRTC / WebView video on iOS (outside app)?
Hello, I am implementing video calling on iOS and need to support Picture in Picture (PiP) behavior similar to FaceTime or WhatsApp. What works Audio continues correctly in background CallKit UI works as expected Video works correctly while the app is in the foreground What I’m trying to achieve When the user presses the Home button or switches apps, I want to show a system Picture in Picture window (floating video outside the app). Current setup Video is rendered via WebRTC The video is displayed inside a WKWebView (HTML / JavaScript) PiP works only while the app is foregrounded When the app backgrounds, the video disappears (only audio remains) Questions Does iOS support system Picture in Picture for: WebRTC video WKWebView / HTML video 2 Is AVPictureInPictureController limited only to: AVPlayerLayer AVSampleBufferDisplayLayer 3 If PiP requires native rendering: Is it mandatory to render WebRTC frames natively using AVSampleBufferDisplayLayer? Is PiP explicitly unsupported for WebView / HTML video? 📌 Clarification Apps like FaceTime and WhatsApp are able to show PiP outside the app. I want to understand whether this behavior is achievable only with native video pipelines, or if WebView-based video is fundamentally restricted by iOS. Any official clarification or documentation reference would be appreciated. Thank you.

Inquiry Regarding Vertical Writing Mode Caret Issues in Safari on iOS
Dear Apple Developer Support, We are currently developing a system that requires the ability to edit Japanese vertical text within the Safari browser on iPhone. During our investigation, we encountered an issue that matches the following WebKit bug: 283620 – Caret Positioning Issues in Vertical Writing Mode We understand that this issue is being addressed in the following pull request: https://github.com/WebKit/WebKit/pull/39939 However, it appears that a complete fix has not yet been implemented. Given this situation, we would like to confirm the following: Is there any known workaround for this issue in iOS 17.5 or iOS 18.5 (the latest versions as of now)? If a workaround exists, could you please provide details? If not, could you share the expected timeline for a full resolution of this issue? Although this appears to be an open-source WebKit issue, we are reaching out to Apple because WebKit is tightly integrated with iOS and Safari, and ultimately delivered as part of the iPhone experience. Thank you very much for your support. Best regards, Takao Kurabayashi

The top of the body pages on my website is cut off on ios
Hello, When I view my website (lasaluade) on iphone or ipad the top of my page bodies are cut off (3-4 first lines). However, on PC, Mac or Android everything is OK (see screenshots). For the record, I built this site with Wordpress and Divi Builder, and I've the same result on Safari and Chrome. Not being a developer, I don't know where to look (I just think it's iOS-related). Have you already had this problem? Do you have any ideas? Thanks for your help!

Safari Flags My Rebuilt Site as Deceptive — Need Review / Whitelisting
Hi Apple Devs & WebKit Team, We operate https://excnum.com — a personal website currently under reconstruction. It's HTTPS-secure, hosted on a clean VPS, and now features a simple placeholder page with no active forms, scripts, or external redirects. However, Safari on both iOS and macOS is flagging it as a “deceptive website”, blocking all access. This warning appears even though: The site uses a valid SSL certificate via Cloudflare There are no redirects, tracking scripts, or dynamic code We serve a static landing page (“under maintenance”) with zero interaction No malware, phishing, or obfuscation exists — verified with multiple tools A review request has already been submitted at: https://websitereview.apple.com We believe the site may have been blacklisted previously under past ownership or prior configurations. It has since been completely restructured and cleared, but the Safari warning persists. This false flag is harming visibility and trust for an otherwise neutral website. Any advice on how to expedite re-evaluation or request a manual delisting from the deceptive site list would be much appreciated. Thank you! — Alex Admin, EXCNUM.COM
