hi, I'm having an issue with Safari devlop menu "Web Extension Background Content" menu item being grayed out. I cant do any debugging right now and its becoming mission critical for us. Any help is appreciated. Thank you,

I'm currently experimenting to add 3d stereo images in HEIC format to my daily Mars Rover Images website https://areo.info/mars20 which can be opened on a Vision Pro. Only a few images are yet converted into that mode, those on the sol 1411 page. As I'm currently only working in the Vision Pro Simulator from Xcode, no real 3d effect if of course visible and I'm curious if anyone using the real hardware can confirm that the images are working. Especially the eye distance correction is important to know about as the Mars Rover camera has a much wider pupil distance than humans and while I entered that distance in the conversion tool, I'm not sure if it worked well. So feedback is welcome! For those who like to try to create stereo images themselves: I used https://developer.apple.com/documentation/ImageIO/writing-spatial-photos to create a HEIC file from two JPEGs.

As of IOS 18.3, there browser.tabs.create methods active property which is supposed to determine whether a tab get open in the active window or not is not working as it should. I have the active property set to false but the tab still gets opened and is active on the window. Tested on older ios versions 18.2 and below and it works as it should. please advise

After the official release of iOS 18.3, our app has collected numerous identical crash logs. These crashes occurred on different devices, but the common denominator is that they all, and only, happened on iOS 18.3. Based on the stack trace, the crash is happening internally within WebKit. The details are as follows: Crashed: com.apple.main-thread 0 WebCore 0x721f9c + 28 1 WebCore 0x15b6924 + 11356 2 WebCore 0x15b174c + 1008 3 WebCore 0x1776e4 + 292 4 WebCore 0x17753c WebCore::SerializedScriptValue::deserialize(OpaqueJSContext const*, OpaqueJSValue const**) + 100 5 WebKit 0x530b28 + 92 6 WebKit 0x5a0d2c + 176 7 WebKit 0x9e74b0 + 956 8 WebKit 0xe43d58 + 392 9 WebKit 0x886ac + 272 10 WebKit 0x88940 + 44 11 WebKit 0x87a74 + 252 12 WebKit 0x875ec + 576 13 JavaScriptCore 0x2f8a48 ***::RunLoop::performWork() + 204 14 JavaScriptCore 0x2f895c ***::RunLoop::performWork(void*) + 36 15 CoreFoundation 0x73f4c CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION + 28 16 CoreFoundation 0x73ee0 __CFRunLoopDoSource0 + 176 17 CoreFoundation 0x76b40 __CFRunLoopDoSources0 + 244 18 CoreFoundation 0x75d3c __CFRunLoopRun + 840 19 CoreFoundation 0xc8284 CFRunLoopRunSpecific + 588 20 GraphicsServices 0x14c0 GSEventRunModal + 164 21 UIKitCore 0x3ee674 -[UIApplication _run] + 816 22 UIKitCore 0x14e88 UIApplicationMain + 340 23 18Birdies 0x1b2d3c main + 14 (main.m:14) 24 ??? 0x1ac161de8 (Missing)

We are using WebKit in our app and recently started noticing a crash occurring on iOS 17 and earlier versions. The crash log shows the following error: Thread 0 Crashed: 0 WebKit 0x00000001a38593cc WebKit::WebPageProxy::updateActivityState(WTF::OptionSet<WebCore::ActivityState>) + 220 (WebPageProxy.cpp:2544) 1 WebKit 0x00000001a39cb1e0 WebKit::WebPageProxy::dispatchActivityStateChange() + 132 (WebPageProxy.cpp:2653) 2 WebKit 0x00000001a3f541f8 WTF::Detail::CallableWrapper<WebKit::WebPageProxy::scheduleActivityStateUpdate()::$_5::operator()() const::'lambda'(), void>::call() + 52 (Function.h:53) 3 JavaScriptCore 0x00000001a48317ec void WTF::dispatchWorkItem<WTF::(anonymous namespace)::DispatchWorkItem>(void*) + 60 (WorkQueueCocoa.cpp:48) 4 libdispatch.dylib 0x00000001964f5dd4 _dispatch_client_callout + 20 (object.m:576) 5 libdispatch.dylib 0x00000001965045a4 _dispatch_main_queue_drain + 988 (queue.c:7898) 6 libdispatch.dylib 0x00000001965041b8 _dispatch_main_queue_callback_4CF + 44 (queue.c:8058) 7 CoreFoundation 0x000000018e623710 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ + 16 (CFRunLoop.c:1780) 8 CoreFoundation 0x000000018e620914 __CFRunLoopRun + 1996 (CFRunLoop.c:3149) 9 CoreFoundation 0x000000018e61fcd8 CFRunLoopRunSpecific + 608 (CFRunLoop.c:3420) 10 GraphicsServices 0x00000001d34d01a8 GSEventRunModal + 164 (GSEvent.c:2196) 11 UIKitCore 0x0000000190c5890c -[UIApplication _run] + 888 (UIApplication.m:3713) 12 UIKitCore 0x0000000190d0c9d0 UIApplicationMain + 340 (UIApplication.m:5303) After investigating, we found that this crash was addressed in this https://github.com/WebKit/WebKit/pull/24778 WebKit PR. However, our app is still crashing for users on older iOS versions where this fix is not available. Is there a known workaround to prevent this crash on affected iOS versions? Any guidance would be greatly appreciated.

We have an app store app that hosts an internal webserver we use as a proxy and it works for a period until iOS 18.3.x decides our cert is no longer valid at which point our customer have reinstall the app. This has only become a problem on iOS18.3. We publish the self-signed with out app, and it is valid and accepted until it's not. We know the cert is valid and our implementation of the local proxy has not changed. If we install a cert on the device and trust it, then the app will start behaving normally again without reinstall. We have replicated this locally and the error we are seeing is: Error Domain=NSURLErrorDomain Code=-1200 "An SSL error has occurred and a secure connection to the server cannot be made." UserInfo={NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, _WKRecoveryAttempterErrorKey=<WKReloadFrameErrorRecoveryAttempter: 0x301111e40>, networkTaskDescription=LocalDataTask <541390E2-65FA-47AB-80B1-10209D6C761A>.<3>, _kCFStreamErrorDomainKey=3, NSErrorPeerCertificateChainKey=( "<cert(0x108e3b700) s: 127.0.0.1 i: 127.0.0.1>", "<cert(0x108e3b980) s: 127.0.0.1 i: 127.0.0.1>" ), NSErrorClientCertificateStateKey=0, NSErrorFailingURLKey=https://localhost:8082/Blablal/?device=ios&sftouch=1&pgport=8081&secure=1, NSErrorFailingURLStringKey=https://localhost:8082/blahblah/?device=ios&sftouch=1&pgport=8081&secure=1, NSUnderlyingError=0x301e1d680 {Error Domain=kCFErrorDomainCFNetwork Code=-1200 "(null)" UserInfo={_kCFStreamPropertySSLClientCertificateState=0, _kCFNetworkCFStreamSSLErrorOriginalValue=-9802, _kCFStreamErrorDomainKey=3, _kCFStreamErrorCodeKey=-9802}}, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <541390E2-65FA-47AB-80B1-10209D6C761A>.<3>" ), _kCFStreamErrorCodeKey=-9802, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <541390E2-65FA-47AB-80B1-10209D6C761A>.<3>, networkTaskMetricsPrivacyStance=NotEligible, NSURLErrorFailingURLPeerTrustErrorKey=<SecTrustRef: 0x302670a50>, NSLocalizedDescription=An SSL error has occurred and a secure connection to the server cannot be made.}

I am currently developing a Chrome, Firefox and Safari web extension, and I am facing a CSP issue on the content script on Safari. The extension I develop has a content script that injects an img tag in the DOM of web pages the user is visiting. That img tag fetches its content at a specific URL. On Chrome and on Firefox, the img tag content fetches the content at the URL with no issue on every web pages, including those that set the CSP header img-src. On Safari, I'm getting the following error on web sites that set the img-src CSP header: Refused to load https://axxlfrmnpq.cloudimg.io/www.macifavantages.fr/wp-content/uploads/2021/06/Garmin-logo.png?func=bound&w=225&h=113 because it does not appear in the img-src directive of the Content Security Policy. Here is the actual CSP img-src header content of the web page where, on Safari, the injected img tag does not load the content at https://axxlfrmnpq.cloudimg.io/www.macifavantages.fr/wp-content/uploads/2021/06/Garmin-logo.png?func=bound&w=225&h=113: Content-Security-Policy: img-src https://secure.adnxs.com https://www.facebook.com https://.garmin.cn 'self' data: .garmin.com .trustarc.com .truste.com https://static.garmincdn.com https://www.google.com https://www.google.co.uk https://prefmgr-cookie.truste-svc.net https://res.cloudinary.com https://res.garmin.com https://.criteo.com https://.doubleclick.net https://www.googleadservices.com https://px.adentifi.com https://rtb.adentifi.com https://.teads.tv https://www.googletagmanager.com https://bat.bing.com https://.yahoo.com https://sync.outbrain.com https://*.google-analytics.com https://stats.g.doubleclick.net https://static.hotjar.com https://script.hotjar.com .akamaihd.net https://.tealiumiq.com https://deploytealium.com https://pixel.mediaiqdigital.com; My question is, is the page CSP blocking the img tag injected in the web page by the extension's content script? If so, is this behavior documented somewhere, or is it a Safari bug? I saw there is a similar post on the forum, but I couldn't find if the issue is a bug or if it's the expected behavior on Safari: https://developer.apple.com/forums/thread/651542?login=true. Thank you very much for your help.

Sometimes the Safari App Extension i'm developing does not show up in my Safari Extensions unless i change mu bundle identifier to some unique name. Even if I delete all other apps i've built with the same (and different) bundle ID, the extension is still does not show up. The only solution for me is to always change the bundle ID. For example: Now it is "kopyl.tab-finder-10" If i change it to "kopyl.tab-finder-11", the extension does show up in the Safari extensions settings page again. Is there any other way to fix it?

Dear Apple Developer Experts, We're experiencing an intermittent issue with WKWebView in our macOS application where local HTML file access is occasionally denied by the sandbox, despite proper implementation and permissions. We seek your guidance in understanding and resolving this issue. Issue Description: The WKWebView occasionally fails to load local HTML files stored in the app's Contents/Resources directory Error occurs in WebKit Networking Process with sandbox denial Issue is intermittent and can be resolved by app restart or WebKit Networking Process restart Affects all local HTML files in the same directory once the issue occurs Technical Details: Error from Kernel Log: 2025-02-07 14:57:17.179821 +0800 kernel Sandbox: com.apple.WebKit.Networking(58661) deny(1) file-read-data /Applications/DingTalk.app/Contents/Resources/webcontent/contact-2024.html WKWebView Delegate Error (captured in WKNavigationDelegate method): (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation withError:(NSError *)error Error Details: Domain: NSPOSIXErrorDomain Code: 1 Description: "Operation not permitted" UserInfo: { networkTaskMetricsPrivacyStance: Unknown, _NSURLErrorFailingURLSessionTaskErrorKey: LocalDataTask &lt;3694CA1E-481B-4E06-975D-E3A56AD56C0F&gt;.&lt;1&gt;, _kCFStreamErrorDomainKey: 1, _kCFStreamErrorCodeKey: 1 } Key Observations: Error is captured in WKNavigationDelegate's didFailProvisionalNavigation method The issue affects all local HTML files in the same directory once it occurs Temporary workarounds we've discovered: Restarting the application completely resolves the issue Without restarting the application, terminating the "WebKit Networking Process" via Activity Monitor causes the process to automatically restart, and this resolves the issue and load works again Additional Information: We've collected complete system diagnostics (system_logs.logarchive) at the time of failure The issue appears similar to discussions in Apple Developer Forums (https://developer.apple.com/forums/thread/110072), though we're uncertain if it's the same root cause We've prepared a minimal demo project demonstrating: Our release version app can be downloaded from: https://dtapp-pub.dingtalk.com/dingtalk-desktop/mac_dmg/Release/M1-Beta/DingTalk_v7.6.45_43521682_universal.dmg?spm=0.0.0.0.UuwovG&amp;file=DingTalk_v7.6.45_43521682_universal.dmg for examining our app's codesign, sandbox, and entitlements configurations if needed Important Investigation Finding: We attempted to simulate the issue by using chmod 000 /path/to/test.html, but this produces a different error: CopyError Domain=NSURLErrorDomain Code=-1102 Description="You do not have permission to access the requested resource." UserInfo={ NSLocalizedDescription=You do not have permission to access the requested resource., NSErrorFailingURLStringKey=file:///Users/sunus/Library/Developer/Xcode/DerivedData/WKWebViewLocalDemo-eumardnlfbmwgnhkaadglsrrhzhs/Build/Products/Debug/WKWebViewLocalDemo.app/Contents/Resources/test.html, NSUnderlyingError=0x600003aedc50 {Error Domain=kCFErrorDomainCFNetwork Code=-1102 "(null)"} } This error is distinctly different from our original issue's "Operation not permitted" error, suggesting that the sandbox denial we're experiencing is not a simple file permission issue. Questions: Is this a known issue with the WebKit sandbox in recent macOS versions? Are there recommended best practices or workarounds to prevent this sandbox denial? Could this be related to the WebKit Networking Process's sandbox configuration? Are there additional diagnostics or logs we should collect to help investigate this issue? We appreciate your assistance in investigating this issue. Please let us know if you need any additional information or clarification.

If "Not Secure Connection Warnings" is enabled in the Settings > App > Safari, are no HTTP connections allowed? Setting NSAppTransportSecurity does not seem to apply either.

I am currently developing an app using WKWebView. In iOS 17, Apple introduced ProxyConfiguration, and I have two questions regarding its usage: Is there a way to use ProxyConfiguration to distinguish between HTTP and HTTPS traffic? I have reviewed the documentation but couldn’t find a clear method for this. As an alternative approach, I am attempting to determine the request scheme within WKWebView and switch proxyConfigurations just before loading the request. My current implementation sends requests to hoge_a by default and switches to hoge_b only for HTTP traffic. 　 if #available(iOS 17.0, *) { if URLString.contains("http:") { webView.configuration.websiteDataStore.proxyConfigurations = [hoge_b] } } webView.load(request) if #available(iOS 17.0, *) { if URLString.contains("http:") { webView.configuration.websiteDataStore.proxyConfigurations = [hoge_a] } } 　 2. Since I modify proxyConfigurations every time webView.load(request) is called, are there any potential issues or concerns with this approach? I would appreciate any insights you may have on either of these questions.

Hello! I've made a Safari extension that supports command "ReTab", and a couple of month ago, adding a customized macOS shortcut for Safari with menu title "ReTab" did trigger the extension. However, it's not working anymore and I'm not sure if it's from macOS/Safari update or because I changed manifest from v2 to v3 - could you help check if there's anything wrong with either the manifest.json or background.js? (the default Cmd+E still works) Thank you in advance! Xun manifest.json: { "manifest_version": 3, "default_locale": "en", "name": "ReTab", "description": "Go to the last active tab with Cmd+E!", "version": "1.4", "homepage_url": "https://LycheeIsle.com", "background": { "service_worker": "background.js" }, "action": { "default_icon": "images/toolbar-icon.svg" }, "permissions": [ "commands", "tabs", "storage" ], "commands": { "ReTab": { "suggested_key": { "default": "Command+E" }, "description": "Go to the last active tab" } }, "options_page": "options.html" } in background.js, I have this line which should listen to the command, and Cmd+E works but any customized shortcut for "ReTab" in Safari doesn't: browser.commands.onCommand.addListener(async (command) => { if (command === "ReTab" || command === "retab") { await retab() } });

Hi, We have a native application with a webview part. When we open the app, we load webview resources in a false foreground. The webview communicates with the native part to query local variables, among other things. We have noticed that for the past few weeks, when the biometric component is presented to enter the fingerprint or faceId, while the component is displayed, the webview does not respond. We do not see the calls made by the webview, nor can we respond to them. Even if you open the Safari debugger, the webview does not respond UNTIL you close the biometric component in the native part. This has created a big problem in our app, and we wanted to know if it is an issue you had on your radar. Thank you very much.

I'm not sure if this is even the right place to ask this, or voice this complaint if there's no fix. If not, please direct me where to go. I'm trying to switch all my development over to Safari, but the tab sidebar is driving me absolutely insane. Let's say I have a bunch of tab groups expanded, and I collapse the sidebar to focus on the webapp I am building. When I toggle to show the sidebar again, every single tab group is collapsed. Why is it 2 clicks to see the tabs in the sidebar? Even with zero tab groups, and just tabs in the workspace, if you collapse the sidebar it'll collapse the list of tabs. Is there some hidden setting for this? Who do we have to complain to?

How can i add Authorization header to a wkwebview. I checked https://developer.apple.com/documentation/foundation/nsurlrequest#1776617 which says Authorization header is a reserved http header and shouldn’t be set. I want to set it when requesting a url to the server which will be used for verification. How can i do that?

Hi all, Chrome has it already - animation-timeline aka scroll-animations. I can nowhere find any informations on what's the status in Safari/Webkit. Seems like they do not have it on the agenda at all? Does anyone know anything - I wanted to push a feature request for that - but also seem there is no feature request list anymore for webkit. See: https://www.w3.org/TR/scroll-animations/ Cheers and kind regards!

We are building a Safari web extension utilising native messaging, to send messages to the Swift native part of the app. We sometimes experience, that the beginRequest handler is executed multiple times, at the same time. We have a special part of the code in the handler, that must be run only once. Because it uses NS defaults storage, and also because it calls our servers. We have tried to use a serial dispatch queue, as well as other locking and mutex techniques, to no success. We suspect that the instances of the handler are isolated in a way, that these locks don’t work (maybe they don’t share memory?). But we are not sure. When looking at os_logs from the handlers, they all share the same PID. Has anyone experienced anything similar and can shed some light on what's going on?

Hi, now we could try WebGPU by manually enabling it in feature flags in no matter Safari or Safari technology preview on macOS. But, do we know when this WebGPU feature would be enabled by default or any plan to enable it by default in Safari? Thanks!

I'm posting a question here as I have encountered an issue while seeking help from engineers in the thread. thread773837 If the "Not Secure Connection Warnings" is enabled in Settings > App > Safari, are HTTP connections not allowed under any circumstances? I also posted a question about NSAllowsLocalNetworking not being applied, and I was informed that ATS (App Transport Security) is not related to SFSafariViewController. If that's the case, what feature causes the error "Safari cannot open the page. Error: Failed to navigate to an HTTP URL with HTTPS-only mode enabled"? I am currently working to resolve this issue.

I'm referring to the following: https://developer.apple.com/documentation/automaticassessmentconfiguration I can't find this information anywhere. I'm wondering if I can enable and disable this function in Safari or other browsers on my website.
