Calling SFContentBlockerManager.reloadContentBlocker from related App extension intermittently fails
I have an app which has at least two extensions: A Content Blocker extension with a request handler that returns an appropriate NSExtensionItem as part of beginRequest. A different file URL is returned depending upon if the content blocking is on or off by a user setting A Safari Web Extension that includes a toolbar button and popover that enables users to enable or disable the ad blocking of the content blocker extension All three targets (App, Content Blocker appex and Web Extension appex) use an App Group default to read and set the on or off status of the content blocking. When the user changes the content blocking status, the app group default is updated and SFContentBlockerManager.reloadContentBlocker(...) is called. The Content Blocker extension reads the default and then returns the appropriate file URL. The issue is, I have noticed that whenever SFContentBlockerManager.reloadContentBlocker(...) is called from the app, Safari always applies the correct rules from the returned file URL. However sometimes when SFContentBlockerManager.reloadContentBlocker(...) is called from the Safari Web Extension using native messaging, Safari does NOT apply the correct rules from the returned file URL. Using logging I have confirmed that the Content Blocker extension always returns the appropriate file URL irrespective if called as a result of the app or the web extension. Despite this, Safari does not seem to always apply the returned file URL rules when it is called from the Safari Web Extension appex. In these cases, quitting Safari and relaunching it seems to make it apply the rules correctly (obviously this is applying it due to its launch state, not due to the Web extension appex asking it to do so at that point). All targets have access to the App Group location where the active content blocking file URL belongs and the inactive content blocking file URL is within the Safari content blocker target as a resource. I don't think this is a memory status issue as I cannot see the Content Blocker extension being killed when it returns complex rules --- the fact it always works when called via the app also seems to rule this possibility out. This brings up a number of questions: Is calling SFContentBlockerManager.reloadContentBlocker(...) from a different appex, of the same app target and app group supported? (it seems to work sometimes and did work in previous versions of the app). Is there an issue that the Content Blocker extension sometimes returns a file URL that perhaps the calling Web Extension appex may not have access to (even though Safari should via the Content Blocker extension)? Any other ideas of why this may not be working correctly? Has anyone else experienced this? It seems to happen on both iOS and macOS Safari using the same codebase.

Push Notifications Not Working in iOS App or Safari Browser Created via PWA Builder
Push Notification Issue in iOS PWA App We’ve been trying to implement push notifications in our iOS app, which is a wrapper around a Vite PWA built using PWA Builder. Here's a detailed overview of the issues we’re facing: Problem Summary We originally had a working Vite PWA and used Firebase Cloud Messaging (FCM) for push notifications. When converting this PWA to an iOS app using PWA Builder: The notification permission prompt did not behave as expected in Safari. Even after requesting permission via a user gesture (e.g., button press), FCM token was not received. On Safari (both Mac and Windows), permission sometimes works, but the token isn’t saved until Safari is closed and reopened. In the iOS PWA app, the FCM token never gets retrieved. We tried the same process on Chrome, and everything works flawlessly there. What We’ve Tried Wrapped the permission request and FCM token logic in a user gesture (e.g., button click), as recommended. Confirmed our manifest includes all necessary fields (see below). Tested across macOS, Windows, Safari (desktop), and the iOS app. Manifest.json { "name": "Periscopio", "short_name": "Periscopio", "start_url": "/", "display": "standalone", "background_color": "#f2f2f2", "lang": "en", "scope": "/", "description": "Facilitates the collection of primary data for market research purposes.", "icons": [ { "src": "/android-chrome-192x192.png", "sizes": "192x192", "type": "image/png", "purpose": "any" }, { "src": "/android-chrome-512x512.png", "sizes": "512x512", "type": "image/png", "purpose": "any" }, { "src": "/maskable_icon_x192.png", "sizes": "192x192", "type": "image/png", "purpose": "maskable" }, { "src": "/maskable_icon_x512.png", "sizes": "512x512", "type": "image/png", "purpose": "maskable" } ], "edge_side_panel": { "preferred_width": 400 }, "display_override": [ "window-controls-overlay", "standalone" ], "theme_color": "#08244c", "orientation": "portrait" } Core Logic (Plain TypeScript) 1. Request Notification Permission + FCM Token async function handleRequestPermission(): Promise<string | null> { try { console.log("Requesting notification permission..."); const permission = await Notification.requestPermission(); console.log("Notification permission result:", permission); if (permission === "denied") { console.error("Notification permission was denied."); return null; } const token = await requestFCMToken(); console.log("FCM Token:", token); if (token) { console.log("Notification setup successful."); return token; } else { console.error("Failed to retrieve FCM token."); return null; } } catch (error) { console.error("Error requesting FCM token:", error); return null; } } 2. FCM Token Logic async function requestFCMToken(): Promise<string | undefined> { try { let permission = Notification.permission; if (permission === "default") { console.log("Requesting notification permission..."); permission = await Notification.requestPermission(); } if (permission === "granted") { console.log("Notification permission granted."); const isSupportedBrowser = await isSupported(); if (!isSupportedBrowser) { console.error("This browser does not support FCM."); return; } const registration = await navigator.serviceWorker.register("/firebase-messaging-sw.js"); console.log("Service Worker registered:", registration); const token = await getToken(cloudMessaging, { vapidKey: "YOUR_PUBLIC_VAPID_KEY_HERE", serviceWorkerRegistration: registration, }); if (token) { console.log("FCM Token:", token); localStorage.setItem("fcmToken", token); return token; } else { console.warn("No registration token available. Request permission to generate one."); return; } } else if (permission === "denied") { console.warn("Permission to notify was denied."); return; } else { console.warn("Notification permission not granted."); return; } } catch (error) { console.error("Error getting FCM token:", error); return; } } Request for Help We’d really appreciate support from anyone who’s successfully implemented FCM push notifications in a Vite PWA wrapped as an iOS app using PWA Builder. Is there something we’re missing about how iOS Safari handles push permissions in PWA mode? Could there be an issue with the service worker or the manifest setup that causes the token not to register? Any Safari-specific quirks to be aware of? Thanks in advance!

Unexpected system confirmation dialog when opening a Universal Link
Subject: Unexpected system confirmation dialog when opening a Universal Link Description of the issue: We’re implementing a login flow using Native iOS apps, Universal Links, and OpenID Connect authentication. Our domain is correctly configured with the apple-app-site-association file, and Universal Links work as expected. However, under certain circumstances, the behavior differs on the same login page: The user connects to the OIDC provider in their mobile browser. Instead of automatically switching to the Native application, a popup asks the user to open the app. The behavior depends on how the login page is opened: When opened in a new browser tab, the Universal Link opens the app immediately without showing any system confirmation dialog. When the same tab is reused without a page refresh, iOS displays a system confirmation dialog asking the user to open the link in the app. This confirmation dialog doesn’t appear in the first scenario. This additional system dialog impacts the user experience, as we aim for a frictionless and seamless login flow with minimal confirmation steps. Question: Why does the app switch work automatically only the first time? Is this intentional iOS behavior? If so, what security requirement or system rule causes a confirmation dialog when reusing the same tab, but not when redirecting in a new tab or pressing a button on the reused tab? Is this expected design, or should we adjust our side to avoid this dialog? Environment details: Verified on two devices iOS versions: 18.7.2, 26.1 Thanks for your help.

WKNavigationDelegate methods not getting called even though
Hi everyone, We work on a macOS plugin which then gets loaded into another application. I'm trying to load a webpage in that application through our plugin using a WKWebView & I set my class as the navigationDelegate for the same. I do not receive any callbacks for the WKNavigationDelegate methods. I have debugged & made sure that the navigationDelegate is actually set to my class. Here is a sample code of what I'm doing : [[NSApplication sharedApplication] runModalForWindow:self.mWindowController.window]; - (void)windowDidLoad { [super windowDidLoad]; [self.window makeKeyAndOrderFront:self]; [self.window orderFrontRegardless]; if (self.mLoadingView == nil) { self.mLoadingView = [[LoadingView alloc] initWithFrame:[[self.window contentView] frame]]; } [[self.window contentView] addSubview:self.mLoadingView]; [self.mLoadingView showLoadingView]; [self.window setLevel:NSMainMenuWindowLevel]; [self loadWebPage]; } -(void)loadWebPage { [self.mWKWebView setUIDelegate:self]; [self.mWKWebView setNavigationDelegate:self]; [self.mWKWebView stopLoading]; NSURL *lURL = [self samplePageURL]; WKNavigation *lNavigation = [self.mWKWebView loadRequest:[NSURLRequest requestWithURL:lURL]]; } - (void)webView:(WKWebView *)pWKWebView didFinishNavigation:(WKNavigation *)pNavigation { [self removeLoadingview]; [self.mWKWebView evaluateJavaScript:@"document.body.setAttribute('oncontextmenu', 'event.preventDefault();');" completionHandler:nil]; } I do not get any calls in the webView:didFinishNavigation: & I also tried other methods like webView:didStartProvisionalNavigation, webView:didFailProvisionalNavigation:withError: etc but did not receive any call in those either. Instead of runModalForWindow: if I use showWindow: on the mWindowController the webpage somehow loads but I still don't get any callbacks & so the loadingview subview is also present. The WKWebView is placed in a storyboard, and I have an IBOutlet connected to it in my class. Has anyone faced a similar issue or can point me to something I might be missing? All help is appreciated. Thanks in advance.

Public API to Open Safari Settings in iOS Browser
Dear Apple Developer Support, I’m developing a Chromium-based iOS browser and want to open the Safari settings page (Settings → Apps→ Safari) like Chrome’s “Import data from Safari” feature, where clicking “Go to settings” opens the Safari settings page. To reproduce this behavior in Chrome: 1.In Chrome, search “Import password from Safari.” 2.Restart Chrome. 3.Go to Chrome → Settings → Safari import → Import to Chrome → Go to settings. 4.You will see it opens Settings → Apps → Safari. Please see the attached file for steps to trigger this feature in Chrome. My attempt with App-Prefs:root=SAFARI only opens the Settings main page ,Is there a public API to open the Safari settings page directly? Look forward to your reply,many thanks

Apple Pay button not showing up in apple pay demo site.
MacOS: 12 ( Monterrey ) Safari: 17.6 Demo Site: https://applepaydemo.apple.com/ At the bottom where the Apple Pay button should appear, I see a warning something like "This browser doesn't support Apple Pay, please use safari" along with a link to requirements for apple pay. All the requirements are fulfilled, OS and Safari's version are above the minimum required. Link was opened in Safari. And the other thing is if I open the same site in Chrome, I can see the apple pay button and when I click on it a QR appears which is the expected behaviour. How to resolve this?

mediaDevices.getUserMedia ignores channelCount with echoCancellation off.
I understand that you want echoCancellation and noiseSuppression in most cases, but I would like to be able to turn off all the filter processes for this particular use case. When I set echoCancellation: false in navigator.mediaDevices.getUserMedia, Safari 26 on MacOS produces stereo recording even if I set channelCount: 1. When I set echoCancellation: true, it produces mono recording as expected. How can I get mono recording with echoCancellation: false and channelCount: 1? Thanks!

blockedByFilter = .specific(domains) does not work on Safari
Hi there, I have a popular open source app called Foqos. What I'm finding in iOS 26 (might even effect older versions) is that when using the webcontent api within Managed settings as the following: store.webContent.blockedByFilter = .specific(domains) It doesn't work on Safari, but does work on third party applications like chrome, firefox, etc. But when using the all and exception enum like the following store.webContent.blockedByFilter = .all(except: domains) This does work on Safari This is pretty inconsistent behavior of the API and should be fixed to match the documentation. Documentation does not mention anything about Safari limitations Again source code is open: https://github.com/awaseem/foqos You can run the app yourself and find the same issues. Is anyone else experiencing this?

Cookie Missing After App Upgrade During OAuth Consent Flow on iOS (Safari ITP?)
Scenario Overview: In our app, we open an in-app browser to complete a third-party consent flow. The sequence is: App → Website A (set cookie and redirect) → Google → Website A (check cookie) → App After upgrading the app, the first consent attempt fails because the cookie cannot be written, causing the check cookie step to fail. However, if we use the native Safari browser, this issue does not occur. Observed Behavior: Scenario Result Upgrade app → Consent ❌ Fail Upgrade app → Consent fail → Consent again immediately ✅ Pass Upgrade app → Consent fail → Upgrade again after 1–2h → Consent ✅ Pass Upgrade app → Consent fail → Upgrade again after 1d → Consent ❌ Fail Install a new app → Consent ✅ Pass Upgrade app → Consent, cancel flow → Consent again ✅ Pass Install new app → Wait for upgrade → Upgrade app → Consent ✅ Pass Install new app → Wait 1–2h → Upgrade app → Consent ✅ Pass Investigation: From Safari documentation, this seems related to Intelligent Tracking Prevention (ITP), which restricts cross-site cookie behavior during first-party interactions. However, I haven’t found a clear mitigation strategy yet. Question: Has anyone encountered similar issues with Safari ITP after app upgrades? Are there recommended approaches to ensure cookies persist across this redirect flow?

Authenticator app not reopening my PWA
I have a simple website, that I would like to make available as a progressive webapp, so I can somewhat customize what happens when people add the website to their homescreen (using the Share button) and maybe, in the future, use PWABuilder or something similar to publish it in some stores. My website needs authentication using OIDC, which after some redirects within the PWA opens an authenticator app on the phone. When the app returns from authenticating however, it opens a new browser tab instead of my PWA, so there is no context and the login fails. I am under the impression that this used to work, but I'm not sure. I'm also not sure what the problem is, I have no idea how, when the Authenticator app opens a URL (which is what I assume is happening under the hood), iOS or Safari or whatever would know which app to open (as the redirect URL is to the OIDC Idp, not the URL of my Web app). Any hints where I could look for a solution? Thanks!

Allow Safari and WKWebView to repaint during resize.
As the title suggests, given today’s overpowered device performance, shouldn’t Safari and WKWebView allow repainting during window resizing? Currently, all WKWebView-based apps pause page rendering during resize. When a user double-clicks the drag region, the sequence goes: pause rendering → enlarge or shrink the window → leave a blank area → repaint the page. The whole process feels inelegant—especially on devices that support ProMotion.

iOS26 WKWebView:Remote page becomes unresponsive after loading local file
Subject: iOS 26 WKWebView: Remote Pages Become Unresponsive After Loading Local HTML Files Description We're experiencing a critical issue with WKWebView in a React Native 0.64.3 application where remote web pages become completely unresponsive after loading local HTML files in iOS 26. It works well before iOS26. Environment: React Native 0.64.3 iOS 26.0 Xcode 26.0.1 Using custom WKWebView implementations in Native modules Problem Details App loads local HTML files using loadFileURL:allowingReadAccessToURL: Later, when loading remote pages via loadRequest:, the remote pages load successfully but become unresponsive to user interactions This occurs even when using different WKWebView instances The issue is reproducible 100% of the time once a local file has been loaded Restarting the app and loading remote pages directly works fine Code Example: // Loading local file (works fine) [self.webView loadFileURL:localFileURL allowingReadAccessToURL:accessURL]; // Later, loading remote page (loads but becomes unresponsive) NSURLRequest *request = [NSURLRequest requestWithURL:remoteURL]; [self.webView loadRequest:request]; What We've Tried: Using different WKWebView instances for local vs remote content Comprehensive cleanup in dealloc (removing all user scripts and message handlers) Loading blank HTML before switching to remote content Using shared WKProcessPool (understanding its limitations in iOS 15+) Ensuring proper decisionHandler management in navigation delegates Resetting WKWebView configuration settings Clearing cookies and cache between loads Using loadFileRequest:allowingReadAccessToURL: instead of loadFileURL: Key Observations: The remote page renders correctly and network requests complete No JavaScript errors in console The view hierarchy appears normal in Debug View Hierarchy Touch events seem to be delivered but not processed by the web content Questions: Has Apple introduced new security restrictions in iOS 26 that affect the transition from file:// URLs to http:// URLs? Are there specific WKWebView configuration changes required for React Native applications in iOS 26? Could this be related to the React Native bridge or JavaScript context persistence? Any insights or workarounds would be greatly appreciated, as this is blocking our iOS 26 compatibility.

LocalOverride Request regular expression broke dev tools
Hello, I'm using Safari 18.2 on Sonoma 14.6.1. I was using the Developer Tools to do a Local Request Override in the Source tab for a CSS file that had a changing query string. I thought I had a good regular expression to catch all variants, but apparently it was too generic and possibly wrong, and made both Source and Network tabs no longer work in my Safari. The regular expression I entered for the Local Request Override was: //build/style.css(?.*)?$ Now my dev tools is broken to the extent that the Source and Network tabs no longer work. The slide-out panel on Source that shows Breakpoints, LocalOverrides, etc no longer shows. The toggle for it does, but does nothing now. UI in general looks a little wack on both tabs. So, since I can't turn off the Local Request Override, I've been trying to locate where Safari may have stored it to manually delete it. Not having a lot of luck on that front. It seems to me that Safari was unable to escape my regular expression correctly and it then causes additional issue. Just a guess though. Any advice or help in getting Safari Source & Network working again / manual removal of the LocalOverride would be greatly appreciated. I'm fluent in OSX and Linux, but grep was not much help surfacing anything that worked. Thanks in Advance, possibly a Safari bug as well.

Issue with opening browser on Apple Watch SE 2 – black screen
Hello, I am experiencing an issue when trying to open the browser on my Apple Watch SE 2 running the latest version, watchOS 11.6. When I attempt to visit any website, the browser opens and displays the URL at the top as if it is loading, but the screen remains black and no content is displayed. The internet connection is available, and all other apps on the watch work normally. This issue occurs only with the browser. I would appreciate any guidance or solution to resolve this problem. Thank you for your assistance.

WKWebView: Fullscreen API User Gesture Bypass
Howdy, WKWebView feature request: allow Fullscreen API without User Gestures similar to ElectronJS' userGesture: true flag that allows devs to bypass user gesture restriction for Fullscreen API and similar executeJavaScript(code[, userGesture]) https://www.electronjs.org/docs/latest/api/web-contents#contentsexecutejavascriptcode-usergesture afaik this is allowed because of a fairly recent update to Chromium that also allows users to give Fullscreen API permissions per domain https://chromeos.dev/en/posts/using-the-fullscreen-api-without-gestures Would be greatly useful for a use case in my cross-platform app, so I can avoid rewriting all platforms to use Chromium Thanks

Public API to Open Safari Settings in iOS Browser
Dear Apple Developer Support, I’m developing a Chromium-based iOS browser and want to open the Safari settings page (Settings → Apps→ Safari) like Chrome’s “Import data from Safari” feature, where clicking “Go to settings” opens the Safari settings page. To reproduce this behavior in Chrome: 1.In Chrome, search “Import password from Safari.” 2.Restart Chrome. 3.Go to Chrome → Settings → Safari import → Import to Chrome → Go to settings. 4.You will see it opens Settings → Apps → Safari. Please see the attached file for steps to trigger this feature in Chrome. My attempt with App-Prefs:root=SAFARI only opens the Settings main page ,Is there a public API to open the Safari settings page directly? Look forward to your reply,many thanks

Apple Pay button not showing up in apple pay demo site.
MacOS: 12 ( Monterrey ) Safari: 17.6 Demo Site: https://applepaydemo.apple.com/ At the bottom where the Apple Pay button should appear, I see a warning something like "This browser doesn't support Apple Pay, please use safari" along with a link to requirements for apple pay. All the requirements are fulfilled, OS and Safari's version are above the minimum required. Link was opened in Safari. And the other thing is if I open the same site in Chrome, I can see the apple pay button and when I click on it a QR appears which is the expected behaviour. How to resolve this?

mediaDevices.getUserMedia ignores channelCount with echoCancellation off.
I understand that you want echoCancellation and noiseSuppression in most cases, but I would like to be able to turn off all the filter processes for this particular use case. When I set echoCancellation: false in navigator.mediaDevices.getUserMedia, Safari 26 on MacOS produces stereo recording even if I set channelCount: 1. When I set echoCancellation: true, it produces mono recording as expected. How can I get mono recording with echoCancellation: false and channelCount: 1? Thanks!

Why do we need request.setvalue for a post request
When practicing a post request today I forgot to use the setvalue method. Why is this method important and needed for a post request? Don't we just encode the data to JSON and put that as the httpbody and make the request

blockedByFilter = .specific(domains) does not work on Safari
Hi there, I have a popular open source app called Foqos. What I'm finding in iOS 26 (might even effect older versions) is that when using the webcontent api within Managed settings as the following: store.webContent.blockedByFilter = .specific(domains) It doesn't work on Safari, but does work on third party applications like chrome, firefox, etc. But when using the all and exception enum like the following store.webContent.blockedByFilter = .all(except: domains) This does work on Safari This is pretty inconsistent behavior of the API and should be fixed to match the documentation. Documentation does not mention anything about Safari limitations Again source code is open: https://github.com/awaseem/foqos You can run the app yourself and find the same issues. Is anyone else experiencing this?

Cookie Missing After App Upgrade During OAuth Consent Flow on iOS (Safari ITP?)
Scenario Overview: In our app, we open an in-app browser to complete a third-party consent flow. The sequence is: App → Website A (set cookie and redirect) → Google → Website A (check cookie) → App After upgrading the app, the first consent attempt fails because the cookie cannot be written, causing the check cookie step to fail. However, if we use the native Safari browser, this issue does not occur. Observed Behavior: Scenario Result Upgrade app → Consent ❌ Fail Upgrade app → Consent fail → Consent again immediately ✅ Pass Upgrade app → Consent fail → Upgrade again after 1–2h → Consent ✅ Pass Upgrade app → Consent fail → Upgrade again after 1d → Consent ❌ Fail Install a new app → Consent ✅ Pass Upgrade app → Consent, cancel flow → Consent again ✅ Pass Install new app → Wait for upgrade → Upgrade app → Consent ✅ Pass Install new app → Wait 1–2h → Upgrade app → Consent ✅ Pass Investigation: From Safari documentation, this seems related to Intelligent Tracking Prevention (ITP), which restricts cross-site cookie behavior during first-party interactions. However, I haven’t found a clear mitigation strategy yet. Question: Has anyone encountered similar issues with Safari ITP after app upgrades? Are there recommended approaches to ensure cookies persist across this redirect flow?

Authenticator app not reopening my PWA
I have a simple website, that I would like to make available as a progressive webapp, so I can somewhat customize what happens when people add the website to their homescreen (using the Share button) and maybe, in the future, use PWABuilder or something similar to publish it in some stores. My website needs authentication using OIDC, which after some redirects within the PWA opens an authenticator app on the phone. When the app returns from authenticating however, it opens a new browser tab instead of my PWA, so there is no context and the login fails. I am under the impression that this used to work, but I'm not sure. I'm also not sure what the problem is, I have no idea how, when the Authenticator app opens a URL (which is what I assume is happening under the hood), iOS or Safari or whatever would know which app to open (as the redirect URL is to the OIDC Idp, not the URL of my Web app). Any hints where I could look for a solution? Thanks!

Allow Safari and WKWebView to repaint during resize.
As the title suggests, given today’s overpowered device performance, shouldn’t Safari and WKWebView allow repainting during window resizing? Currently, all WKWebView-based apps pause page rendering during resize. When a user double-clicks the drag region, the sequence goes: pause rendering → enlarge or shrink the window → leave a blank area → repaint the page. The whole process feels inelegant—especially on devices that support ProMotion.

iOS26 WKWebView:Remote page becomes unresponsive after loading local file
Subject: iOS 26 WKWebView: Remote Pages Become Unresponsive After Loading Local HTML Files Description We're experiencing a critical issue with WKWebView in a React Native 0.64.3 application where remote web pages become completely unresponsive after loading local HTML files in iOS 26. It works well before iOS26. Environment: React Native 0.64.3 iOS 26.0 Xcode 26.0.1 Using custom WKWebView implementations in Native modules Problem Details App loads local HTML files using loadFileURL:allowingReadAccessToURL: Later, when loading remote pages via loadRequest:, the remote pages load successfully but become unresponsive to user interactions This occurs even when using different WKWebView instances The issue is reproducible 100% of the time once a local file has been loaded Restarting the app and loading remote pages directly works fine Code Example: // Loading local file (works fine) [self.webView loadFileURL:localFileURL allowingReadAccessToURL:accessURL]; // Later, loading remote page (loads but becomes unresponsive) NSURLRequest *request = [NSURLRequest requestWithURL:remoteURL]; [self.webView loadRequest:request]; What We've Tried: Using different WKWebView instances for local vs remote content Comprehensive cleanup in dealloc (removing all user scripts and message handlers) Loading blank HTML before switching to remote content Using shared WKProcessPool (understanding its limitations in iOS 15+) Ensuring proper decisionHandler management in navigation delegates Resetting WKWebView configuration settings Clearing cookies and cache between loads Using loadFileRequest:allowingReadAccessToURL: instead of loadFileURL: Key Observations: The remote page renders correctly and network requests complete No JavaScript errors in console The view hierarchy appears normal in Debug View Hierarchy Touch events seem to be delivered but not processed by the web content Questions: Has Apple introduced new security restrictions in iOS 26 that affect the transition from file:// URLs to http:// URLs? Are there specific WKWebView configuration changes required for React Native applications in iOS 26? Could this be related to the React Native bridge or JavaScript context persistence? Any insights or workarounds would be greatly appreciated, as this is blocking our iOS 26 compatibility.

LocalOverride Request regular expression broke dev tools
Hello, I'm using Safari 18.2 on Sonoma 14.6.1. I was using the Developer Tools to do a Local Request Override in the Source tab for a CSS file that had a changing query string. I thought I had a good regular expression to catch all variants, but apparently it was too generic and possibly wrong, and made both Source and Network tabs no longer work in my Safari. The regular expression I entered for the Local Request Override was: //build/style.css(?.*)?$ Now my dev tools is broken to the extent that the Source and Network tabs no longer work. The slide-out panel on Source that shows Breakpoints, LocalOverrides, etc no longer shows. The toggle for it does, but does nothing now. UI in general looks a little wack on both tabs. So, since I can't turn off the Local Request Override, I've been trying to locate where Safari may have stored it to manually delete it. Not having a lot of luck on that front. It seems to me that Safari was unable to escape my regular expression correctly and it then causes additional issue. Just a guess though. Any advice or help in getting Safari Source & Network working again / manual removal of the LocalOverride would be greatly appreciated. I'm fluent in OSX and Linux, but grep was not much help surfacing anything that worked. Thanks in Advance, possibly a Safari bug as well.

Issue with opening browser on Apple Watch SE 2 – black screen
Hello, I am experiencing an issue when trying to open the browser on my Apple Watch SE 2 running the latest version, watchOS 11.6. When I attempt to visit any website, the browser opens and displays the URL at the top as if it is loading, but the screen remains black and no content is displayed. The internet connection is available, and all other apps on the watch work normally. This issue occurs only with the browser. I would appreciate any guidance or solution to resolve this problem. Thank you for your assistance.

WKWebView: Fullscreen API User Gesture Bypass
Howdy, WKWebView feature request: allow Fullscreen API without User Gestures similar to ElectronJS' userGesture: true flag that allows devs to bypass user gesture restriction for Fullscreen API and similar executeJavaScript(code[, userGesture]) https://www.electronjs.org/docs/latest/api/web-contents#contentsexecutejavascriptcode-usergesture afaik this is allowed because of a fairly recent update to Chromium that also allows users to give Fullscreen API permissions per domain https://chromeos.dev/en/posts/using-the-fullscreen-api-without-gestures Would be greatly useful for a use case in my cross-platform app, so I can avoid rewriting all platforms to use Chromium Thanks
