Hi there, I'm experiencing several crashes on JavaScriptCore pas_panic_on_out_of_memory_error, only on devices with tvOS 15.4 and 15.4.1. This happens with users using the app for several hours as well as 5 seconds after launching the app. Devices: AppleTV6,2 and AppleTV5,3 Thread 14 — JavaScriptCore pas_panic_on_out_of_memory_error (JavaScriptCore) JavaScriptCore bmalloc_try_iso_allocate_impl_impl_slow (JavaScriptCore) JavaScriptCore bmalloc_heap_config_specialized_local_allocator_try_allocate_small_segregated_slow (JavaScriptCore) JavaScriptCore bmalloc_allocate_impl_casual_case (JavaScriptCore) JavaScriptCore ***::String::String(char16_t const*, unsigned int) (JavaScriptCore) JavaScriptCore JSC::LiteralParser<char16_t>::parsePrimitiveValue(JSC::VM&) (JavaScriptCore) JavaScriptCore JSC::LiteralParser<char16_t>::parse(JSC::ParserState) (JavaScriptCore) JavaScriptCore JSC::jsonProtoFuncParse(JSC::JSGlobalObject*, JSC::CallFrame*) (JavaScriptCore) JavaScriptCore llint_entry (JavaScriptCore) JavaScriptCore llint_entry (JavaScriptCore) JavaScriptCore llint_entry (JavaScriptCore) JavaScriptCore llint_entry (JavaScriptCore) JavaScriptCore vmEntryToJavaScript (JavaScriptCore) JavaScriptCore JSC::Interpreter::executeCall(JSC::JSGlobalObject*, JSC::JSObject*, JSC::CallData const&, JSC::JSValue, JSC::ArgList const&) (JavaScriptCore) JavaScriptCore JSC::boundThisNoArgsFunctionCall(JSC::JSGlobalObject*, JSC::CallFrame*) (JavaScriptCore) JavaScriptCore vmEntryToNative (JavaScriptCore) JavaScriptCore JSC::Interpreter::executeCall(JSC::JSGlobalObject*, JSC::JSObject*, JSC::CallData const&, JSC::JSValue, JSC::ArgList const&) (JavaScriptCore) JavaScriptCore JSC::profiledCall(JSC::JSGlobalObject*, JSC::ProfilingReason, JSC::JSValue, JSC::CallData const&, JSC::JSValue, JSC::ArgList const&) (JavaScriptCore) JavaScriptCore JSObjectCallAsFunction (JavaScriptCore) JavaScriptCore -[JSValue invokeMethod:withArguments:] (JavaScriptCore) ITMLKit -[IKJSObject invokeMethod:withArguments:] (ITMLKit) ITMLKit -[IKJSEventListenerObject invokeMethod:withArguments:thenDispatchEvent:extraInfo:] (ITMLKit) ITMLKit __43-[IKJSXMLHTTPRequest setRequestReadyState:]_block_invoke (ITMLKit) ITMLKit -[IKAppContext _doEvaluate:] (ITMLKit) ITMLKit -[IKAppContext _evaluate:] (ITMLKit) ITMLKit __41-[IKAppContext evaluate:completionBlock:]_block_invoke (ITMLKit) ITMLKit -[IKAppContext _sourcePerform] (ITMLKit) ITMLKit -[IKConcurrentEvaluator lockSchedulingForEvaluation:] (ITMLKit) ITMLKit IKRunLoopSourcePerformCallBack (ITMLKit) CoreFoundation __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ (CoreFoundation) CoreFoundation __CFRunLoopDoSource0 (CoreFoundation) CoreFoundation __CFRunLoopDoSources0 (CoreFoundation) CoreFoundation __CFRunLoopRun (CoreFoundation) CoreFoundation CFRunLoopRunSpecific (CoreFoundation) ITMLKit -[IKAppContext _jsThreadMain] (ITMLKit) Foundation __NSThread__start__ (Foundation) libsyste...ad.dylib _pthread_start (libsystem_pthread.dylib) libsyste...ad.dylib thread_start (libsystem_pthread.dylib) This issue seems very similar to this existing thread, although not sure its related

I am a newby to JavaScript, suggested to me to use to automate the task of opening of a Web page, selecting three internal buttons in sequence to download the underlying chart data. I have created the App via Automator on macOS, to run the Script, successfully open the Web Page, but cannot find a way to select and click() on the buttons. Can someone please help me. Robert. This is the code suggested by Grok 3 Beta, but I see this error: Error: First parameter passed to Document Constructor must be an object. function run(input, parameters) { var Safari = Application('Safari'); Safari.activate(); // Open the AEMO data dashboard (Grok 3 Beta recomendation opens the web page correctly) Safari.Document().make(); Safari.windows[0].currentTab.url = 'https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem'; delay(10); // Wait for page to load // Click the Fuel Mix tab (target the active in the tabs) Safari.Document(0).doJavaScript("document.querySelector('.tabs .active').click()"); delay(5); // Wait for tab content to load // Select 48 hrs from the dropdown Safari.Document(0).doJavaScript("document.querySelector('#interval').value = '48H'; document.querySelector('#interval').dispatchEvent(new Event('change'))"); delay(5); // Wait for selection to take effect // Click the download button Safari.Document(0).doJavaScript("document.querySelector('.visualisation-icon-button').click()"); return input; }

In the safari or chrome app, when I want to change tabs, I can go into a grid view of the tabs. In this grid, each tab shows the content of the page. When I click on one of the tabs, the content of the page expands to fill the entire screen (and shrinks when I go back to grid). I'm creating my own browser and I'm trying to replicate this same functionality. I'm using WebKit on XCode 16.4, iOS 18. However, I'm unable to figure out how Chrome and Safari did this. First, I thought that I could take a snapshot of the page and then use that image as the thumbnail. However, very often the image is of the wrong size - likely due to the webview shrinking for the animation. Making the animation wait until the image is made available did help in making it more consistent. The above errors happen whenever I spam the new tab and then click the tab grid button. It only is misaligned on the very last new tab. Please help on this. // OpenedTab.swift Button(action: { tab.getThumbnail { tabManager.selectedTab = nil } }) { ZStack { Image(systemName: "square") .resizable() .frame(width: 25, height: 25) Text(tabManager.tabs.count.description) .font(.subheadline) } } // TabState.swift func getThumbnail(completionHandler: (() -> Void)? = nil) { webView.takeSnapshot(with: nil) { img, err in if let err = err { print("Snapshot err: \(err)") } else { self.thumbnail = img completionHandler?() } } } Also, something I'm noticing is that for some reason, the image is slightly bigger than the header of the tab card. It also happens in the progress view if the thumbnail isn't available. The images above show it too. I have no clue why this is happening and I would love advice on this too. struct TabCardView: View { @StateObject var manager = TabManager.shared @ObservedObject var tab: TabState var namespace: Namespace.ID @State var width: CGFloat = 0 var body: some View { GeometryReader { geo in VStack(spacing: 0) { HStack(spacing: 1) { Text(tab.title ?? tab.url.host() ?? "") .font(.caption2) .padding(.horizontal, 4) .padding(.vertical, 10) Button(action: { manager.close(tab: tab) }) { Image(systemName: "multiply") } } .frame(height: 40) .frame(width: geo.size.width) // .padding(.horizontal, 7) .background(.tertiary) .matchedGeometryEffect(id: tab.id.uuidString + "title", in: namespace) ZStack { if let thumbnail = tab.thumbnail { Image(uiImage: thumbnail) .resizable() .aspectRatio(contentMode: .fill) .frame(width: geo.size.width, height: 160, alignment: .top) .clipped() } else { Color.black.brightness(0.8) ProgressView() } } .frame(width: geo.size.width, height: 160) .matchedGeometryEffect(id: tab.id.uuidString + "container", in: namespace) } .frame(width: geo.size.width) } .frame(height: 200) .clipShape(RoundedRectangle(cornerRadius: 16)) .shadow(radius: 2) .padding(.all, 7) .overlay( RoundedRectangle(cornerRadius: 20) .stroke(.blue, lineWidth: manager.previousTab?.id == tab.id ? 5 : 0) ) .shadow(radius: 1) } }

The “Add to Home Screen” feature for bookmarks is not working in Safari on iOS 26.

Dear Apple Developer Support Team, I am writing regarding critical issues we are facing with Safari web push notifications in our application iLiveMyLife.io, which is severely impacting our ability to maintain reliable communication with our users. Issue Description: We are experiencing persistent problems with Safari push notification tokens expiring or becoming invalid without any notification to our server. This creates several critical issues: Users stop receiving notifications without any indication of failure Our notification delivery system has no way to detect token expiration The expiration appears to happen frequently (seemingly almost daily in some cases) There is no reliable mechanism to re-establish push communication without users manually revisiting the app Technical Impact: Our messaging functionality becomes completely unreliable We must resort to email or SMS as fallback mechanisms, which is not feasible for a real-time communication platform This makes building any reliable messaging application on Safari practically impossible The Broader Context: What makes this situation particularly challenging is that all potential alternative browser APIs that could help address this issue appear to be deliberately disabled or restricted in Safari: Background Service Workers don't function in the background on iOS Safari Background Sync API is not supported WebSockets cannot operate when the app is closed There's no way to programmatically check the validity of push tokens The combination of these limitations creates a situation where developers have no viable technical path to build reliable notification systems for PWAs on Safari. This appears to be a systematic restriction rather than individual API limitations. Requested Information: Is there a recommended approach to detect Safari push token expiration? Are there alternative notification mechanisms for PWA applications on Safari that offer more reliability? Is there documentation on the lifecycle of Safari push tokens that could help us implement proper handling? Are there plans to improve the Web Push API implementation in Safari to address these reliability issues? Could you clarify if these limitations are intentional design decisions or technical constraints that might be addressed in future updates? Business Impact: This issue fundamentally undermines our platform's core functionality. For a collaborative tool, reliable notifications are essential - users cannot collaborate effectively if they miss updates because their push tokens silently expired. The current state creates confusion among our users, who don't understand why they suddenly stop receiving notifications. Any guidance or assistance you could provide would be greatly appreciated. We're committed to providing an excellent experience on Safari, but the current push notification limitations make this extremely challenging. Thank you for your time and consideration. Best regards, Ilya

I have compiled some Java code to WebAssembly via TeaVM and wrapped it in a PWA. The resulting code runs nicely in Firefox and Chrome but throws an exception in Safari. CompileError: WebAssembly.Module doesn't parse at byte 1657: invalid extended GC op 24, in function at index 2251 Can anybody tell me what's wrong with that code? I mean it can't be so bad if Firefox and Chrome can parse and run it without problems. I am using the most recent versions of all browsers and the offending code can be found here: Run the demo via: https://mpmediasoft.de/demos/Emmentaler/Emmentaler-Demo-TeaVM-Wasm/index.html The offending wasm file is: https://mpmediasoft.de/demos/Emmentaler/Emmentaler-Demo-TeaVM-Wasm/tvw/ModelBridgeTeaVM.wasm With Safari the demo just shows some empty space instead of a complex polygon. You can see the error in the javascript console of Safari.

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

Chrome's Incognito mode can not open app from universal link on iOS. It's opened a web page instead of launching the app even the app already installed on the iOS device.

I have a UI application built with the Vue framework, using Vuetify for the UI components. There's a div with the class v-application--wrap, which is provided by Vuetify. This class internally includes the following style rule. .v-application--wrap { backface-visibility: hidden; display: flex; flex: 1 1 auto; flex-direction: column; max-width: 100%; min-height: 100vh; position: relative; } The pages were rendering correctly up to version 18.3, but after upgrading to version 18.4, we encountered layout issues related to height. Upon investigation, we discovered that the min-height property was no longer being interpreted or applied correctly. Replacing min-height with height resolved the issue, and the pages began loading as expected. Any insights into why this behavior is occurring would be greatly appreciated.

It seems that in iOS 18.5+ built with Xcode 16.4+, there has been a breaking change since 18.4 with 16.3 within WebKit and how the navigationAction.sourceFrame property is initialized when implementing the decidePolicy delegate method. The flow goes: Implement a WKNavigationActionDelegate with decidePolicy Call WKWebView.loadHTMLString("some-string", baseURL: nil) Upon loading the HTML content, read the value of navigationAction.sourceFrame within the decidePolicy method of the WKNavigationActionDelegate On iOS 18.4 (and below) with Xcode 16.3 (and below); navigationAction.sourceFrame is <uninitialized> On iOS 18.5+ with Xcode 16.4+: navigationAction.sourceFrame is already initialized and is equal to navigationAction.targetFrame It appears that this change was made between minor versions of Xcode and is unexpected behavior of a minor version. Not only was this not called out in the release notes for Xcode 16.4 and iOS 18.5, but it's technically also a breaking change to the WebKit API. Can we get insight on why this change was made and what Apple's policy is on breaking changes between minor versions of Xcode/iOS?

We are encountering a download issue in Safari 18.2 on macOS Sequoia 15.2 where file downloads initiated by our AngularJS application (such as Excel exports) are silently blocked. There are no errors in the browser console, and the download does not occur. Interestingly, after testing on Safari 18.3 with Sequoia 15.3, the downloads worked as expected. However, the problem reappeared on Safari 18.4 with Sequoia 15.4. We suspect that recent changes in Safari’s security or download handling may be preventing downloads triggered via asynchronous JavaScript (e.g., AJAX calls) that are not initiated directly by user interaction. We would appreciate any insights, suggestions, or possible workarounds from the community. Looking forward to your guidance on this matter.

Is the new Observations API for WebPage not available in Beta 1 as demoed in the WWDC video? I get this error even though Observation is imported.

I have "http://localhost:8080" showing the index page I've created but php is not handled though an extension is running. Haven't even tried mySQL yet but since there is no reference to it in https.conf the same problem will exist. Homebrew extension running also. https.conf: #PHP was deprecated in macOS 11 and removed from macOS 12 #LoadModule php7_module libexec/apache2/libphp7.so There are no php.so files on my machine and again no mention of mysql What should I enter in http.conf to activate these functionalities? Thanks. PS could you reference a tutorial on using Safari and Web inspector

Hello Apple App Review Team, We are using Privy to enable sign in with Farcaster in our app. Privy is a 3rd party authentication SDK, and it currently opens the authentication URL using the system browser. Unfortunately, this behavior is handled internally by Privy and we do not have access or control to override it in order to present the sign-in flow in-app using SFSafariViewController. We understand the importance of maintaining a seamless and secure user experience, and we fully support the use of SFSafariViewController or ASWebAuthenticationSession. However, since Privy does not expose an option to change this behavior at the moment, we are limited by their current implementation. We have reached out to the Privy team requesting a change or improvement that would allow us to use SFSafariViewController instead of the external browser. In the meantime, we would appreciate your guidance on how to proceed, or whether an exception could be granted due to this 3rd party SDK limitation. Thank you for your understanding and support.

When a DNR rule is set for a specific URL and the request receives a server-side redirect (e.g., 302) to a different URL that does not match the urlFilter, the rule still seems to apply to the redirected request. We are using macOS 15.4 and Safari 18.4. For example, consider two sequential calls: call1 and call2. call1 triggers a 302 redirect to call2. A DNR rule is created to add a "Cookie" header to call1 based on its URL. Unexpectedly, the same cookie is also added to call2, even though call2's URL does not match the rule's urlFilter. This results in the Set-Cookie response from call1 being ignored, and call2 receiving the manually set cookie instead—leading to incorrect behavior. This issue doesn't occur in Chrome or Firefox, where the rule is not applied to the redirected request if the URL no longer matches. We are looking for assistance in fixing these issues and having our Safari Extension function the same as it does in Firefox and Chrome.

Hi all, Question: Can Apple confirm that, on macOS 15 without MDM/supervision, there is no supported API, entitlement, auth right, or config file that can enable a Safari App Extension without some form of user interaction? Environment • OS / Safari: macOS 15.0.1 (Sequoia), Safari 18.x • Distribution: Signed, notarized, stapled PKG installs a host app that contains a Safari App Extension • Management: No MDM allowed (and thus no supervision) • Goal: Have the extension come up enabled immediately after install, without requiring the user to click the checkbox in Safari Settings ▸ Extensions What we already know / tried Normal install flow – After PKG install, the extension shows up disabled. User must check the box to enable. SFSafariApplication.showPreferencesForExtension(...) – We can deep‑link the user to our row, but they still need to click “Enable.” Accessibility/UI scripting – We can script the click if the user grants our helper Accessibility permission. That still involves user interaction. .mobileconfig with Safari Extensions Management (AlwaysOn) – From what I can tell, this requires a supervised device enrolled in MDM. Installing that profile manually on an unsupervised Mac does not enforce the “AlwaysOn” state. Auth rights / Developer mode – Looked at auth.db rights like com.apple.Safari.allow-unsigned-app-extensions, and the Develop menu “Allow Unsigned Extensions.” Neither appears to auto‑enable a signed extension, and we don’t want to use private/unsupported APIs anyway. Thanks in advance for any clarification.

Our team has implemented a video player using the HTML5 tag, but we have identified an issue with loading media files. While Safari on iOS 18.0 downloads each TS file listed in the m3u8 playlist correctly, on iOS 18.4 and 18.5, a single TS file is downloaded repeatedly. Our statistics indicate that approximately six requests are made per second for the same TS file. Is this intended behavior? If not, are there any known workaround or solutions? If this issue is due to the OS or browser, are there any plans to address it in iOS 18.6 or a future release? Could you advise on the proper channel to submit a bug report for this issue? Similar issues have been reported in the past with WKWebView. The previous thread is here: https://developer.apple.com/forums/thread/784134

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!

Hello, ive been dealing with this glitch all year that hasnt happened last year. When I watch a video on public safari and then it exit the video it immediately takes me to the private tab but when I go on the private tab to watch videos and exit out it takes me back to the website just like normal. Its a pretty annoying bug and I watch all my videos in the private tab because of it
