New WebView in iOS 26 Pull To refresh support
The new WebView implementation in *OS 26 versions is a very valuable addition to the SwiftUI toolset. I was experimenting with it and was wondering how to implement a Pull To Refresh. While this was easily achievable with the "old" WKWebView I was not able to find an API to implement, for example, a page reload when the user uses a pull to refresh gesture. I tried to attach to a .refreshable(_:) modifier to the WebView but without success. Is there an official API for that or should maybe .refreshable(_:) already work and it's just a bug or is it simply not yet supported? Here is a minimal example I was trying but didn't succeed: struct ContentView: View { @State private var page = WebPage() var body: some View { NavigationStack { WebView(page) .refreshable { page.reload() } } } } Any help is much appreciated. Thank you!

[iOS 26 Beta] event.target.value is always empty — only from specific script domains
Hey everyone, After installing iOS 26 beta, I started noticing unexpected behavior in our input event handlers. Specifically, when users type into an field, event.target.value is always an empty string — but only when the JS file is loaded from a specific domain (e.g., t1.daumcdn.net). The exact same code works perfectly when hosted on other domains like t2.daumcdn.net or search1.daumcdn.net. 👉 I created a demo here: 🔗 https://codepen.io/bzasklcu-the-sans/pen/rNXogxL The scripts loaded from each domain are 100% identical (apart from the top-level selector). Before iOS 26 beta, this worked fine. I suspect this is related to ITP or some new cross-origin behavior in Safari, but I’d love to know if anyone else is running into this — or if someone knows a workaround. Thanks!

Crash in WKScriptMessageHandler — CFRelease / CoreFoundation on iOS with WKWebView
We are building a hybrid iOS app using Angular (web) rendered inside a WKWebView, hosted by a native Swift app. Communication between the Angular UI and native Swift code is done using WKScriptMessageHandler. The app mostly works without issues, but in rare edge cases, we’re seeing crashes on the main thread, and the crash is reported in Firebase Crashlytics. The root cause appears related to CFRelease and WKScriptMessageHandler. Here’s the relevant crash stack: Crashed: com.apple.main-thread 0 CoreFoundation 0xbfac CFRelease + 44 1 CoreFoundation 0xa734 __CFURLDeallocate + 128 2 CoreFoundation 0x730c _CFRelease + 292 3 libobjc.A.dylib 0x4e28 AutoreleasePoolPage::releaseUntil(objc_object**) + 204 4 libobjc.A.dylib 0x4cbc objc_autoreleasePoolPop + 260 5 WebKit 0x99f194 WebKit::WebUserContentControllerProxy::didPostMessage(WTF::ObjectIdentifierGeneric<WebKit::WebPageProxyIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WebKit::FrameInfoData&&, WTF::ObjectIdentifierGeneric<WebKit::ScriptMessageHandlerIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, std::__1::span<unsigned char const, 18446744073709551615ul>, WTF::CompletionHandler<void (std::__1::span<unsigned char const, 18446744073709551615ul>, WTF::String const&)>&&) + 680 6 WebKit 0x1b358 WebKit::WebUserContentControllerProxy::didReceiveMessage(IPC::Connection&, IPC::Decoder&) + 392 7 WebKit 0xe86b0 IPC::MessageReceiverMap::dispatchMessage(IPC::Connection&, IPC::Decoder&) + 272 8 WebKit 0x23c0c WebKit::WebProcessProxy::didReceiveMessage(IPC::Connection&, IPC::Decoder&) + 44 9 WebKit 0xe3f054 IPC::Connection::dispatchMessage(WTF::UniqueRef<IPC::Decoder>) + 252 10 WebKit 0x332d4 IPC::Connection::dispatchIncomingMessages() + 744 11 JavaScriptCore 0x58a7c WTF::RunLoop::performWork() + 204 12 JavaScriptCore 0x599a4 WTF::RunLoop::performWork(void*) + 36 13 CoreFoundation 0x56328 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 14 CoreFoundation 0x562bc __CFRunLoopDoSource0 + 176 15 CoreFoundation 0x53dc0 __CFRunLoopDoSources0 + 244 16 CoreFoundation 0x52fbc __CFRunLoopRun + 840 17 CoreFoundation 0x52830 CFRunLoopRunSpecific + 588 18 GraphicsServices 0x11c4 GSEventRunModal + 164 19 UIKitCore 0x3d2eb0 -[UIApplication _run] + 816 20 UIKitCore 0x4815b4 UIApplicationMain + 340 21 APP1 0xa2f80 main + 21 (AppDelegate.swift:21) 22 ??? 0x1c234eec8 (シンボルが不足しています) Steps: WebView: WKWebView Message passing: WKScriptMessageHandler → passing data from Angular → Swift WKWebView is long-lived and reused Native is using WKUserContentController.add(_:name:) to register handlers Crashes are intermittent (hard to reproduce), but often follow: Screen sleep/wake Push notification open Angular calling native immediately after resume Questions: Has anyone seen this specific crash pattern involving CFRelease and WKScriptMessageHandler? Are there known WebKit or CoreFoundation bugs related to WKScriptMessageHandler and retained URLs or message content? Thank you for your help!

Frontend Does Not Display Password Validation Error (e.g., “Password Cannot Contain Your Name”)
Description When creating an Apple ID via the web form, if the user’s chosen password contains their own name, the server correctly returns an error (e.g., "Password cannot contain your name") in the PUT request's JSON response. However, this error is not shown on the frontend, leaving users unaware of why the form silently fails or stalls. Steps to Reproduce Go to the Apple ID account creation page (https://appleid.apple.com/account). Enter valid account details where the password includes the user's first or last name (e.g., Johnacb2331!l for a user named John Doe). Complete all fields, including phone number verification and captcha. Submit the form and monitor the Network tab in your browser’s DevTools. Observe that the form appears to hang, loop, or silently fail. Open the PUT request to /account — the response JSON will contain the relevant validation error (e.g., “Password cannot contain your name”), but the user is not shown this. Expected Behavior The password validation error (e.g., containing the user’s name) should be immediately displayed in the UI next to the password field to inform the user and allow for correction. Actual Behavior No error is shown in the UI. The form appears to fail silently, leaving the user confused. The actual reason for failure is only visible through browser developer tools in the PUT response payload. Impact This can lead to: User frustration and confusion Increased support overhead Poor UX in a critical flow (account creation) Environment Browser: chrome 136.0.7103.114 Platform: Web (https://appleid.apple.com) Date observed: 31/5/25 Suggested Fix Ensure that password validation messages from backend responses surface in the frontend, especially for common user input issues like including names in passwords. No screenshots as I can not create a new account

iOS26 Safari rendering bug even on latest beta 3
I am testing stuff on a website, and it worked well on any mobile browser till iOS18. Now that I am testing iOS26, even with the latest BETA (3) everything works smoothly on any other mobile browser but Safari. Previously I had the bug, which now has been patched, for status-bar, which was flickering too, but popover and page issue seems still there. I have persistent popover and ajax navigation, and both are rendering with bugs and fouc while view/page changes. Example: If I have an element which must stay on its place and its width is 100vw: while page changes it blinks, shrinks, flicker and jumps on rendering, while it simply must stay as is.. Animations and page transitions work smoothly on Chrome mobile (latest iOS 26 beta 3) , while breaking on Safari. I did open a feedback FB18328720, but seems no one caring. Any idea guys? ** Video of the bug (which is huge!) : ** https://youtube.com/shorts/rY3oxUwDd7w?feature=share Cheers

WKWebView: Failed to acquire RBS assertion 'WebKit Media Playback'
Hi there! I'm new to App Development and I'm running into the following error when playing audio on a website loaded through a WKWebView: 0x112000cc0 - ProcessAssertion::acquireSync Failed to acquire RBS assertion 'WebKit Media Playback' for process with PID=70.197, error: Error Domain=RBSServiceErrorDomain Code=1 "(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)" UserInfo={NSLocalizedFailureReason=(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)} Looking through this forum, it seems more people have this issue, yet no one has found a solution (or posted it...). The solutions that I did find (Background Modes capability, webView.configuration.allowsInlineMediaPlayback = true), did nothing. To make sure the issue had nothing to do with my own code, I created an empty project to reproduce the issue. I'm not sure on the best way to share it, but it's a small file (forgive me, I have no clue what it does, actually chatGPT made it for me. My real application is a WebApp wrapped with Capacitor, so it handles all the Swift stuff) import SwiftUI import WebKit struct WebView: UIViewRepresentable { let urlString: String func makeUIView(context: Context) -> WKWebView { let webView = WKWebView() webView.configuration.allowsInlineMediaPlayback = true webView.configuration.allowsAirPlayForMediaPlayback = true webView.navigationDelegate = context.coordinator return webView } func updateUIView(_ uiView: WKWebView, context: Context) { if let url = URL(string: urlString) { let request = URLRequest(url: url) uiView.load(request) } } func makeCoordinator() -> Coordinator { Coordinator(self) } class Coordinator: NSObject, WKNavigationDelegate { var parent: WebView init(_ parent: WebView) { self.parent = parent } func webView(_ webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation!, withError error: Error) { print("Web page loading failed: \(error.localizedDescription)") } } } struct WebViewDemo: View { var body: some View { NavigationView { WebView(urlString: "https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_audio_all") .navigationBarTitle("Web View") } } } struct WebView_Previews: PreviewProvider { static var previews: some View { WebViewDemo() } } Nothing special, right? When I build the app and navigate to a website that has an tag (https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_audio_all). I still see the error when I play the audio. It plays nonetheless, but the error is there. I'm not at all interested in actually playing audio in the background/when the app is closed/suspended. I just want the error to go away! I've tried different iOS versions (14,15,16,17), but the problem persists. Anyone know what's happening?

Unable to send a message from website to Safari web extension
I've been unable to successfully get a webpage to send a message to a Safari web extension, no matter what I try doing. I've added the following to my manifest.json file, and it's running manifest v3 { "externally_connectable": { "matches": [ "*://mywebsite.com/*", "*://localhost:3000/*" ] } } My web page executes the following code snippet. I've tried this both while running my site locally (on localhost) and pushed to production. let safariExtensionId = "co.companyname.productname.Extension (ABCD1234)" browser.runtime.sendMessage(safariExtensionId, { greeting: "hello"}, function(response) { console.log("Received response from background page"); console.log(response.farewell); } ); In the Safari web extension's background.js file, I've added the following onMessageExternal listener: browser.runtime.onMessageExternal.addListener((message, sender, sendResponse) => { console.log("Received message from the sender."); console.log(message.greeting); sendResponse({ farewell: "Goodbye!" }); }); This is directly copied from the instructions in this WWDC video: https://developer.apple.com/documentation/safariservices/messaging-between-a-webpage-and-your-safari-web-extension It's also extremely difficult to debug what's happening since the extensions service working frequently does not appear in the Web Extension Background Content menu Is there something I'm doing wrong, or a bug I'm not aware of?

WebXR Consent Dialog
Based on the "Build immersive web experiences with WebXR"-Video for visionOS there is no way to disable the consent prompts for entering an immersive experience or consent hand-tracking. For the microphone it's possible to "greenlight" specific websites for mic input, which works great. I'd welcome it, if it were possible to add specific websites in the settings, in which those consent dialogs aren't shown each time. In my opinion, the user interaction through a button that launches the experience would be sufficient to not disorient.

Cancelling the "pick up annotation" animation
While implementing Apple Maps into our web application, I have a scenario where I want to be able to drag and move some of my custom annotations around. While that is working, when "picking up" the annotation before dragging it, there is an animation which I believe is to represent the human interaction of picking up a pin from a map, I would like to cancel that animation and thought that would be possible by calling preventDefault() in the emitted long-press event, which the documentation states that annotations should emit if they are draggable. The thing is that I don't get this event to emit when long pressing an annotation. So I believe that I have found a bug. It's in this paragraph in the documentation https://developer.apple.com/documentation/mapkitjs/handling-map-events#Respond-to-map-interaction-events A long press occurs on the map outside an annotation. A long press may be the beginning of a panning or pinching gesture on the map. You can prevent the gesture from starting by calling the preventDefault() method of the event. Annotations need to be draggable to dispatch long-press events. In anybody else experiencing this or do you see any clear fix for this? Maybe there is another way to cancel that "picking up the annotation for dragging" animation. I have seemed to try anything else.

In Safari's JavaScript geolocation, is altitude based on MSL or WGS84 ellipsoid?
Hello all, I'm trying to retrieve geolocation data on the web, but I'm having trouble with the altitude value, which seems to differ from what I get on Android. When using navigator.geolocation.getCurrentPosition in Safari, is the altitude value based on mean sea level, or is it ellipsoidal altitude based on the WGS84 ellipsoid? altitude (WebKit JS): https://developer.apple.com/documentation/webkitjs/coordinates/1631861-altitude altitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/altitude ellipsoidalAltitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/ellipsoidalaltitude If anyone has any insight into this topic I would greatly appreciate it!

iOS 26 crash – CALayer position contains NaN when selecting text / showing magnifier / selecting Image's Text in WKWebView
Environment • Device: any iPhone running iOS 26 Developer Beta 5 (23A5308g) • Xcode: 16.3 Short description The app crashes the moment the user tries to long-press to select text inside a WKWebView, double-tap an image with Text (magnifier appears) The exception is CALayer position contains NaN. frame = (nan,0;0,48) chorPoint=(inf, 0) and it is thrown in the UI process. Build & run any project that hosts a WKWebView. Inject the following CSS via script (this is what we do to suppress the native callout menu): WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:[WKWebViewConfiguration new]];

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?

Frontend Does Not Display Password Validation Error (e.g., “Password Cannot Contain Your Name”)
Description When creating an Apple ID via the web form, if the user’s chosen password contains their own name, the server correctly returns an error (e.g., "Password cannot contain your name") in the PUT request's JSON response. However, this error is not shown on the frontend, leaving users unaware of why the form silently fails or stalls. Steps to Reproduce Go to the Apple ID account creation page (https://appleid.apple.com/account). Enter valid account details where the password includes the user's first or last name (e.g., Johnacb2331!l for a user named John Doe). Complete all fields, including phone number verification and captcha. Submit the form and monitor the Network tab in your browser’s DevTools. Observe that the form appears to hang, loop, or silently fail. Open the PUT request to /account — the response JSON will contain the relevant validation error (e.g., “Password cannot contain your name”), but the user is not shown this. Expected Behavior The password validation error (e.g., containing the user’s name) should be immediately displayed in the UI next to the password field to inform the user and allow for correction. Actual Behavior No error is shown in the UI. The form appears to fail silently, leaving the user confused. The actual reason for failure is only visible through browser developer tools in the PUT response payload. Impact This can lead to: User frustration and confusion Increased support overhead Poor UX in a critical flow (account creation) Environment Browser: chrome 136.0.7103.114 Platform: Web (https://appleid.apple.com) Date observed: 31/5/25 Suggested Fix Ensure that password validation messages from backend responses surface in the frontend, especially for common user input issues like including names in passwords. No screenshots as I can not create a new account

iOS26 Safari rendering bug even on latest beta 3
I am testing stuff on a website, and it worked well on any mobile browser till iOS18. Now that I am testing iOS26, even with the latest BETA (3) everything works smoothly on any other mobile browser but Safari. Previously I had the bug, which now has been patched, for status-bar, which was flickering too, but popover and page issue seems still there. I have persistent popover and ajax navigation, and both are rendering with bugs and fouc while view/page changes. Example: If I have an element which must stay on its place and its width is 100vw: while page changes it blinks, shrinks, flicker and jumps on rendering, while it simply must stay as is.. Animations and page transitions work smoothly on Chrome mobile (latest iOS 26 beta 3) , while breaking on Safari. I did open a feedback FB18328720, but seems no one caring. Any idea guys? ** Video of the bug (which is huge!) : ** https://youtube.com/shorts/rY3oxUwDd7w?feature=share Cheers

WKWebView: Failed to acquire RBS assertion 'WebKit Media Playback'
Hi there! I'm new to App Development and I'm running into the following error when playing audio on a website loaded through a WKWebView: 0x112000cc0 - ProcessAssertion::acquireSync Failed to acquire RBS assertion 'WebKit Media Playback' for process with PID=70.197, error: Error Domain=RBSServiceErrorDomain Code=1 "(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)" UserInfo={NSLocalizedFailureReason=(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)} Looking through this forum, it seems more people have this issue, yet no one has found a solution (or posted it...). The solutions that I did find (Background Modes capability, webView.configuration.allowsInlineMediaPlayback = true), did nothing. To make sure the issue had nothing to do with my own code, I created an empty project to reproduce the issue. I'm not sure on the best way to share it, but it's a small file (forgive me, I have no clue what it does, actually chatGPT made it for me. My real application is a WebApp wrapped with Capacitor, so it handles all the Swift stuff) import SwiftUI import WebKit struct WebView: UIViewRepresentable { let urlString: String func makeUIView(context: Context) -> WKWebView { let webView = WKWebView() webView.configuration.allowsInlineMediaPlayback = true webView.configuration.allowsAirPlayForMediaPlayback = true webView.navigationDelegate = context.coordinator return webView } func updateUIView(_ uiView: WKWebView, context: Context) { if let url = URL(string: urlString) { let request = URLRequest(url: url) uiView.load(request) } } func makeCoordinator() -> Coordinator { Coordinator(self) } class Coordinator: NSObject, WKNavigationDelegate { var parent: WebView init(_ parent: WebView) { self.parent = parent } func webView(_ webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation!, withError error: Error) { print("Web page loading failed: \(error.localizedDescription)") } } } struct WebViewDemo: View { var body: some View { NavigationView { WebView(urlString: "https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_audio_all") .navigationBarTitle("Web View") } } } struct WebView_Previews: PreviewProvider { static var previews: some View { WebViewDemo() } } Nothing special, right? When I build the app and navigate to a website that has an tag (https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_audio_all). I still see the error when I play the audio. It plays nonetheless, but the error is there. I'm not at all interested in actually playing audio in the background/when the app is closed/suspended. I just want the error to go away! I've tried different iOS versions (14,15,16,17), but the problem persists. Anyone know what's happening?

Unable to send a message from website to Safari web extension
I've been unable to successfully get a webpage to send a message to a Safari web extension, no matter what I try doing. I've added the following to my manifest.json file, and it's running manifest v3 { "externally_connectable": { "matches": [ "*://mywebsite.com/*", "*://localhost:3000/*" ] } } My web page executes the following code snippet. I've tried this both while running my site locally (on localhost) and pushed to production. let safariExtensionId = "co.companyname.productname.Extension (ABCD1234)" browser.runtime.sendMessage(safariExtensionId, { greeting: "hello"}, function(response) { console.log("Received response from background page"); console.log(response.farewell); } ); In the Safari web extension's background.js file, I've added the following onMessageExternal listener: browser.runtime.onMessageExternal.addListener((message, sender, sendResponse) => { console.log("Received message from the sender."); console.log(message.greeting); sendResponse({ farewell: "Goodbye!" }); }); This is directly copied from the instructions in this WWDC video: https://developer.apple.com/documentation/safariservices/messaging-between-a-webpage-and-your-safari-web-extension It's also extremely difficult to debug what's happening since the extensions service working frequently does not appear in the Web Extension Background Content menu Is there something I'm doing wrong, or a bug I'm not aware of?

WebXR Consent Dialog
Based on the "Build immersive web experiences with WebXR"-Video for visionOS there is no way to disable the consent prompts for entering an immersive experience or consent hand-tracking. For the microphone it's possible to "greenlight" specific websites for mic input, which works great. I'd welcome it, if it were possible to add specific websites in the settings, in which those consent dialogs aren't shown each time. In my opinion, the user interaction through a button that launches the experience would be sufficient to not disorient.

Cancelling the "pick up annotation" animation
While implementing Apple Maps into our web application, I have a scenario where I want to be able to drag and move some of my custom annotations around. While that is working, when "picking up" the annotation before dragging it, there is an animation which I believe is to represent the human interaction of picking up a pin from a map, I would like to cancel that animation and thought that would be possible by calling preventDefault() in the emitted long-press event, which the documentation states that annotations should emit if they are draggable. The thing is that I don't get this event to emit when long pressing an annotation. So I believe that I have found a bug. It's in this paragraph in the documentation https://developer.apple.com/documentation/mapkitjs/handling-map-events#Respond-to-map-interaction-events A long press occurs on the map outside an annotation. A long press may be the beginning of a panning or pinching gesture on the map. You can prevent the gesture from starting by calling the preventDefault() method of the event. Annotations need to be draggable to dispatch long-press events. In anybody else experiencing this or do you see any clear fix for this? Maybe there is another way to cancel that "picking up the annotation for dragging" animation. I have seemed to try anything else.

In Safari's JavaScript geolocation, is altitude based on MSL or WGS84 ellipsoid?
Hello all, I'm trying to retrieve geolocation data on the web, but I'm having trouble with the altitude value, which seems to differ from what I get on Android. When using navigator.geolocation.getCurrentPosition in Safari, is the altitude value based on mean sea level, or is it ellipsoidal altitude based on the WGS84 ellipsoid? altitude (WebKit JS): https://developer.apple.com/documentation/webkitjs/coordinates/1631861-altitude altitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/altitude ellipsoidalAltitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/ellipsoidalaltitude If anyone has any insight into this topic I would greatly appreciate it!

iOS 26 crash – CALayer position contains NaN when selecting text / showing magnifier / selecting Image's Text in WKWebView
Environment • Device: any iPhone running iOS 26 Developer Beta 5 (23A5308g) • Xcode: 16.3 Short description The app crashes the moment the user tries to long-press to select text inside a WKWebView, double-tap an image with Text (magnifier appears) The exception is CALayer position contains NaN. frame = (nan,0;0,48) chorPoint=(inf, 0) and it is thrown in the UI process. Build & run any project that hosts a WKWebView. Inject the following CSS via script (this is what we do to suppress the native callout menu): WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:[WKWebViewConfiguration new]]; NSString *js = @"document.documentElement.style.webkitUserSelect='none';" "document.documentElement.style.webkitTouchCallout='none';"; [webView evaluateJavaScript:js completionHandler:nil]; [self.view addSubview:webView];
