WKWebView based Browser Yubikey&WebAuthn Support
TLDR: I’m searching for a possibility to allow the usage of passkeys and hardware keys for any website in a wkwebview INFO: The browser is macOS ONLY Hi, I couldn’t really find documentation or forums posts on how to implement Webauthn for signin or hardware security keys for a second factor. Or rather where those events are triggered to be handled. In Safari you have that popover, that lets you either authenticate through Passwords or with a security key. When I visit webauthn.io for testing and click either register or authenticate I get Told not to present authorization sheet: Error Domain=com.apple.AuthenticationServicesCore.AuthorizationError Code=1 "(null)" ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "(null)" If I add func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping @MainActor (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) and func webView(_ webView: WKWebView, authenticationChallenge challenge: URLAuthenticationChallenge, shouldAllowDeprecatedTLS decisionHandler: @escaping @MainActor (Bool) -> Void) it doesn’t seem to change anything. I found something about the ASWebAuthenticationSessionWebBrowserSupported entitlement, but by my understanding this is used so a browser can get opened upon some other app calling a ASWebAuthenticationSession. Has anyone some guidance for me? I feel like webauthn and yubikey support are important security measures for our users. https://codeberg.org/miakoring/Amethyst/src/branch/main/Amethyst/Shared/ViewComponents/WebKit/WebViewModel.swift is the code for my webviewmodel. Delegates are in the Delecate folder https://codeberg.org/miakoring/Amethyst/src/branch/main/Amethyst/Shared/ViewComponents/WebKit

When will CSS animation-timeline hit Safari?
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!

Add Authorization header to WKWebView.
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?

Issue: Webview does not respond when the biometric component is presented
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.

WKWebView/Sandbox Intermittent Local File Access Denial in macOS Sandbox Environment
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 <3694CA1E-481B-4E06-975D-E3A56AD56C0F>.<1>, _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&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. STEPS TO REPRODUCE Open App Then loads the local file in /WKWebViewLocalDemo.app/Contents/Resources/test.html PS, We also submit a DTS & Feedback DTS:Case-ID: 11876957 Feedback-ID: FB16493282 sysdiagnose is in the Feedback-ID: FB16493282 is uploaded

Share session from ASWebAuthenticationSession with WKWebView
Hello everyone, In my application, i have implemented authentication using ASWebauthenticationSession. However, when redirecting the user to a WKWebView, no cookies are shared, causing the session to be lost and requiring the user to log in again. Is there a way to share cookies between the two? If not, what would be the best approach to set up authentication that ensures SSO when switching to a WebView ? Thank you very much for your help !

iOS 18.3.x no longer accepts self singed certificates
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.}

WebKit Null pointer WebPageProxy::updateActivityState on iOS 17
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.

Fitbit Google login Issue in WKWebView
I’m developing an app that has a Fitbit login page embedded in a WKWebView. On the Fitbit login page, there is a Google login button. When I try to log in to Fitbit via Google, some devices redirect back to the Fitbit login page even after entering the correct Google credentials. However, it works on the second attempt. I tested the same URL in the default browser, and it works fine when the page is loaded in the browser instead of inside the WebView. I tried the following workarounds but was unable to fix the issue: 1. Enabled JavaScript in WebView. 2. Tried cookie synchronization between WKWebsiteDataStore and HTTPCookieStorage.

WKWebView IOSurface leak?
While investigating an apparent IOSurface leak in my app, which makes heavy use of WKWebViews, I found that if I simply create an empty web view and start changing page zoom by pinching, I can see the number of IOSurfaces steadily increasing. Programmatically changing the zoom also has this effect. The controller below gets to 3.58GB of persistent IOSurface objects in about 20 seconds. This behavior continues indefinitely. Is this a leak? I don't think this is just related to zooming, tapping and scrolling also seem to leak IOSurfaces. The problem I was investigating occurs without any of this, just dynamically modifying a web page containing svgs, but I wonder if this is somehow related, as the allocation stack traces are all the same. I'm running on iOS 18.1.1 on an iPad Pro 12.9in 4th gen. class LeakTestController: UIViewController { private(set) var webView: WKWebView! init() { super.init(nibName: nil, bundle: nil) } required init?(coder: NSCoder) { nil } override func viewDidLoad() { let config = WKWebViewConfiguration() webView = WKWebView(frame: .zero, configuration: config) view.addSubview(webView) webView.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ view.topAnchor.constraint(equalTo: webView.topAnchor), view.bottomAnchor.constraint(equalTo: webView.bottomAnchor), view.leadingAnchor.constraint(equalTo: webView.leadingAnchor), view.trailingAnchor.constraint(equalTo: webView.trailingAnchor) ]) webView.loadHTMLString("hi", baseURL: nil) startZooming() } func startZooming() { Task.init { while true { try await Task.sleep(nanoseconds: 1000000) webView.pageZoom = 0.5 try await Task.sleep(nanoseconds: 1000000) webView.pageZoom = 1 } } } } The stack trace for the allocations is: IOSurfaceClientLookupFromMachPort -[IOSurface initWithMachPort:] WebCore::IOSurface::createFromSendRight(WTF::MachSendRight const&&) decltype(auto)

Local network permission provided but App still has no access (Mac Catalyst)
Context: I work on Home Assistant App, a smart home platform which connects locally to their smart home server. The Apps essentially needs the local network permission and every single user gives the permission, but some in macOS 15.3 are reporting that even though the permission is given, the app still reports it is not, and logs also confirm that. Since there is no way to reset local network permission on macOS I am kind of on a dead end here. How can the user get out of this situation? I also read https://developer.apple.com/forums/thread/763753?answerId=824036022&replyId=824036022 and the TN3179 but still no solutions for my case.

Modifying the native selection menu ios
I am working on a React Native application where I want to modify the native text selection menu (the menu that appears when you long-press on text). Specifically, I want to add a custom option alongside the default ones like Copy, Look Up, Translate, Search Web, and Share. Is there a way to modify the native text selection menu inside a WebView on iOS? How can I add a custom menu option to the default text selection menu while keeping all the default options intact?

App crashes when the app is moved to background
After the app is put in background for sometime and the app crashes, Some cases have the webView involvement before putting the app in to background for quite sometime and pulled into foreground.

CallDirectoryExtention - How to remove a phone number entry that has already been added if a specific value is retrieved.
The App has the ability to use WebKit and display web pages and the ability to add phone numbers to CallDirectory at specific timing. In this App, when the App is launched or when the Add Contact button on the web page is pressed, CallDirectoryExtention is reloaded from the host app (WebKit-viewController), the phone number is retrieved from the server, and the entry is updated. I would like to add a process to remove the already added phone number entry when a specific value is retrieved from the application server. The specific process we wish to implement is as follows. Step 1: Use URLsession to retrieve values from the application server. (ViewController) Step 2: If the value is a specific value, call a Function that deletes the CallDirectoryExtention entry. (ViewController) Step 3: Delete all entries for the registered phone numbers.
 However, I am aware that I have to use reloadExtension() to call the CallDirectoryExtention process from ViewController on Step2. if I do so, CallDirectoryHandler.beginRequest() will be processed, and I am wondering if it is not possible to execute only the Function that deletes the entry. Is there a way to run only the Function that deletes the CallDirectoryExtention entry from the host app(viewController)?

XMLHttpRequest cannot load https://demo2.artios.cz/app37g/v105/php/endpoint.php due to access control checks
Hi, we are experiencing a strange issue with our Web App. Our web app runs entirely on the same domain , and we are making several AJAX requests to the same server. The Error occurs only on Iphones, the app works completely fine on androids and computers. Most of the requests work fine, but suddenly, one specific request always fails with the following error: XMLHttpRequest cannot load https://demo2.artios.cz/app37g/v105/php/endpoint.php due to access control checks What we have checked so far: ✅ CORS headers seem correct. Also we operate entirely on the same domain, client and server. ✅ The same request works fine in computer and android devices. ✅ The issue occurs only on iPhone (tested on Chrome and Safari). ✅ Some requests to the same endpoint pass, but suddenly, this specific request always fails. ✅ There is no OPTIONS preflight request logged in the network tab, but we use only simple requests. ✅ We are making a POST request with multipart/form-data. What is Your advice, or where I can find more info about this error? We do not think the CORS is the problem. We have tried to inspect with WebInspector but with no relevant answers. Thank You very much!

Content blockers: ignore-previous-rules not working?
In my content blocker I have a bunch of rules that block some content in Safari, but I want my users to be able to whiltelist a website so the blocker rules don't apply on that site. I have something like this: { "action": { "type":"css-display-none", "selector":"a[href*='Bobbins']" }, "trigger": { "url-filter":".*" } }, { "trigger": { "url-filter": ".*", "if-domain": ["*mydomain.com"] }, "action": { "type": "ignore-previous-rules" } } I think that should block any a link where the href includes Bobbins but not if the site is mydomain.com. However, that simply doesn't work. It doesn't matter what I put in the array of domains to whitelist, it just doesn't apply it. In every case, the a link is blocked. How do you actually whitelist a website in a Safari content blocker?

WKWebView: Select Text and scroll beyond what's visible
Prime Objective I am trying to have a scroll view with a fixed header, a fixed footer, and a WKWebView in between. Using JavaScript, the height of the webView is determined and set to be large enough to hold the entire content. The Problem When selecting text on the webView, the view does not scroll when the edges are reached (this works if the webView is shown without being embedded in a Scroll view, or if it is the last element) What did I try? I tried reading the scroll view, or adding a gesture recognizer, but all of that does not work because the selection is essentially a system task Sourcecode Sourcecode to demonstrate the issue can be found on GitHub

Allowing workaround for FamilyActivityPicker crash
As discussed and acknowledged here, there is a known bug with the FamilyActivityPicker. When a user expands a category that contains enough tokens to exceed the 50mb memory limit, the FamilyActivityPicker crashes. This happens quite frequently for heavy Safari users. An apple engineer mentioned on this thread that WebDomains shown in the picker are present based on the last 30 days of usage data as surfaced by WebKit. Is there any way a user can clear these WebDomains? Either programatically through our app or any other process we can guide them to as a workaround while this issue is getting fixed?

ServiceWorker Support in iOS WKWebView
Is ServiceWorker supported on WKWebView? As per Mozilla Developer Network(MDN Web) docs[1] its not supported, but our research shows that ServiceWorker becomes available for a domain in WKWebView 1) if the domain is allowlisted in app-bound domains[2] or 2) if app is registered as default browser(this can not be considered for our app as its not a browser). How to enable ServiceWorker on WKWebView? Is adding domain as app-bound domain the right/only way to enable ServiceWorker on WKWebView? We didn't find any official documentation about this. Can WebView get ServiceWorker support by default without enabling app bound domains since that is not an option for our app? Our app needs to support more than 10 domains. Powerful APIs such as JavaScript injection, cookie manipulation, event handlers are by default available to all domains/WebView instances even if App doesn't enable app-bound domains. Is it possible to do same for ServiceWorker? If ServiceWorker can not be supported by default then can Apple provide a feature by which ServiceWorker will be enabled in App for all the domains? Apple enforces maximum of 10 app-bound domains. Is it possible to remove this limit and provide a way to dynamically add to this list at the time of a request?
