webkitEnterFullScreen API is supported on iOS for video element, but not for a div element. Also as a fullscreen demo website shown, Safari on macOS supports div element but not on iOS. Is there any plan to add the support in iOS? If not is there any way to fullscreen a div element or make it run as fullscreen on Safari iOS?

I'm trying to embed a self-built copy of the WebKit frameworks to a macOS app. Most importantly I hope to get some features to work which Safari offers, but WKWebView in macOS doesn't (getDisplayMedia, Service Workers, WebInspector). Many years ago I was successful in using a self-built WebKit copy in this Mac app, but it seems the WebKit framework got more complex since them, I guess because of WKWebView's architecture. That time I had to open the projects for the main frameworks in Xcode, select the framework bundle in the target and change the "Installation Directory" setting to the path @executable_path/../Frameworks. After building WebKit using the build script, I could use otool -L to confirm the changed installation path, which then was displayed for example as @executable_path/../Frameworks/WebCore.framework/Versions/A/WebCore I tried the same with a current WebKit build: I copied the products for WebKit.framework, WebCore.framework, JavaScriptCore.framework, WebKitLegacy.framework, WebGPU.framework and WebInspectorUI.framework to my app and added it to the "Frameworks, Libraries and Embedded Content" section in the Project's Target/General tab and selected "Embed & Sign" for each framework. In "Build Phases" I made sure that WebCore.framework and WebGPU.framework are only in the "Copy Files" phase (Destination Frameworks) and not in "Link Binary with Libraries", as WebCore is linked through the WebKit umbrella framework and WebGPU gave another error (not sure about how to deal with that framework, as in the system it's in a PrivateFrameworks subfolder). In "Build Settings" I made sure that @executable_path/../Frameworks is entered for "Runpath Search Paths" (it was already probably because of Cocoapods, together with @loader_path/../Frameworks. When I build my app, the system's WebKit version is used. Only when I add the environment variable DYLD_FRAMEWORK_PATH with value @executable_path/../Frameworks in the run scheme, the embedded self-build WebKit frameworks are used. Because of currently necessary backward compatibility my app can use the legacy WebView or WKWebView. The legacy WebView works perfectly with the embedded WebKitLegacy.framework. But if I try to open any URL in WKWebView, no content is rendered and in the console output I can see: Safe Exam Browser[21391:145678] [Process] 0x10c67d760 - [PID=0] WebProcessProxy::didFinishLaunching: Invalid connection identifier (web process failed to launch) Safe Exam Browser[21391:145678] [Process] 0x10c67d760 - [PID=0] WebProcessProxy::processDidTerminateOrFailedToLaunch: reason=4 Safe Exam Browser[21391:145678] [ProcessSuspension] 0x10c005040 - [PID=0, throttler=0x10c67d8d8] ProcessThrottler::Activity::invalidate: Ending background activity / 'WebProcess initialization' Safe Exam Browser[21391:145678] [Process] 0x10c67d760 - [PID=0] WebProcessProxy::shutDown: Safe Exam Browser[21391:145678] [Process] 0x7fbe89064020 - [pageProxyID=40, webPageID=41, PID=0] WebPageProxy::processDidTerminate: (pid 0), reason 4 2022-02-14 12:53:01.764074+0100 Safe Exam Browser[21391:145678] [Process] 0x10c67d760 - [PID=0] WebProcessProxy::processTerminated: Safe Exam Browser[21391:145678] [Loading] 0x7fbe89064020 - [pageProxyID=40, webPageID=41, PID=0] WebPageProxy::dispatchProcessDidTerminate: reason=Crash Safe Exam Browser[21391:146842] [SEBOSXWKWebViewController webViewWebContentProcessDidTerminate:<Safe_Exam_Browser.SEBOSXWKWebView: 0x7fbe88f8b1c0>] I have the impression that the web process might fail to launch because I didn't embed all necessary parts of the self-built WebKit (the product folder contains a large number of XPC, dylib and .a files). Or some additional paths have to be adjusted before building WebKit, so that the embedded frameworks/libraries are used and not the system provided ones. I also looked at the bundle of the Safari Technology Preview and can see some similarities but also differences. I would be grateful if anybody could provide me with information how to embed a self-built copy of WebKit into a macOS app. Unfortunately I didn't find any Mac open source browser using an embedded copy of WebKit to get some inspiration from.

Hi Apple engineers! We are making an iOS browser and are planing to deliver a feature that allows enterprise customers to use a MAM key to set a PAC file for proxy. It's designed to support unmanaged device so the MDM based solutions like 'Global HTTP Proxy MDM payload' or 'Per-App VPN' simply don't work. After doing some research we found that with WKWebView, the only framework allowed on iOS for web browsing, there's no API for programmatically setting proxy. The closes API is the WKURLSchemeHandler, but it's for data management not network request interception, in other word it can not be used to handle HTTP/HTTPS request well. When we go from the web-view level to the app level, it seems there's no API to let an app set proxy for itself at an app-level, the closest API is Per-App VPN but as mentioned above, Per-App VPN is only available for managed device so we can't use that as well. Eventually we go to the system level, and try to use Network Extension, but there's still obstacles. It seems Network Extension doesn't directly provide a way to write system proxy. In order to archive that, we may have to use Packet Tunnel Provider in destination IP mode and create a local VPN server to loop back the network traffic and do the proxy stuff in that server. In other word, the custom VPN protocol is 'forward directly without encryption'. This approach looks viable as we see some of the network analysis tools use this approach, but still I'd like to ask is this against App Store Review Guidelines? If the above approach with Network Extension is not against App Store Review Guidelines, I have a further question that, what is the NEProxySettings of NETunnelNetworkSettings for? Is it the proxy which proxies the VPN traffic (in order to hide source IP from VPN provider) or it is the proxy to use after network traffic goes into the virtual private network? If none of the above is considered recommended, what is the recommended way to programmatically set proxy on WKWebView on an unmanaged device (regardless of where the proxy runs, web-view/app/system)?

I'm working on a regular website, in which I'm trying to debug using the (MacOS) Safari Development tools. Since updating my Simulator to iOS 16.4, console.log is no longer displayed in the Console. Even when executing it directly in the console (console.log('test');), it's not printed. Now, I've read that this is a feature for debugging in-app browser content (https://webkit.org/blog/13936/enabling-the-inspection-of-web-content-in-apps/) but can't find the regular web workaround here. TL;DR: No longer see console.log in iOS 16.4 Safari when debugging from my Mac. Thanks in advance for your suggestions!

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?

I'm working on a web browser App that's distributed via the App Store. This app renders web pages using WKWebView. Our users are requesting a way for us to allow them to play videos in Picture in Picture. After some investigation, we noticed that in order to allow PiP videos in our browser in the sandboxed environment, we need to add the com.apple.PIPAgent entitlement under the com.apple.security.temporary-exception.mach-lookup.global-name option. We tried to submit our app with this entitlement, but unfortunately, we were rejected: Guideline 2.4.50) - Performance We've determined that one or more temporary entitlement exceptions requested for this app are not appropriate and will not be granted: com.apple.security.temporary-exception.mach-lookup.global-name com.apple.P|PAgent We would like to have access to this entitlement so we can offer PiP to our users. We already created a radar about this as well: FB13814428 Additionally, we have another radar (FB13557716) regarding allowing the usage of a private flag _allowsPictureInPictureMediaPlayback, which would also be required to enable us to use PiP. Is there any way in which we can currently enable PiP? Would opening a TSI help here?

navigator.permissions.query -&gt; permissionStatus.onchange is Supposed to listen to the event of a change in permissions in the browser settings. This works for all browsers, but in Safari for iOS and MacOS this seems to be broken in the currently recent versions 17.x Example: navigator.permissions.query({ name: 'notifications' }).then((permissionStatus) =&gt; { permissions = permissionStatus.state; // this value gets set correctly permissionStatus.onchange = () =&gt; { // This will not get executed when permissions have been changed // within the safari settings app, or iOS Settings for PWA or Safari }; }); Can someone from Apple's Webkit Team please comment on this? Thank you. T.

Since iOS 18.1 launched as a beta, we've been getting reports from end users on iPhone 15 Pro and iPhone 15 Pro Max specifically. They're reporting that our WebView is unable to load our local HTML content. I'm curious if anyone else has had their app or users run into this issue? So far I've tried installing the most recent XCode Beta 16B5014f and installed an 18.1 emulator, but our app worked fine. It's also working fine on all my real devices, but we don't have a 15 Pro to test on. I'm curious if this is related to the processor on these devices and how they are intended to support Apple's new AI coming in 18.1.

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.

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?

I'm hoping that others may be able to assist with my first app submission. **Guideline 2.1 - Performance - App Completeness Issue Description** The app still exhibited one or more bugs that would negatively impact App Store users. Bug description: The app did not load its content. Review device details: Device type: iPad Air (5th generation) OS version: iPadOS 18.3.1 The app pulls in a website embedded to allow them to login to their accounts/place orders. I've tested it on multiple physical devices and using the simulator. It works fine and loads without any issues. The review team would not give me any other information or support to help get this app approved. Any help would be appreciated.

Hi, we were recently approved for the com.apple.developer.web-browser.public-key-credential entitlement and have added it to our app. It initially worked as expected for a couple of days, but then it stopped working. We're now seeing the same error as before adding the entitlement: 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)" Do you have any insights into what might be causing this issue? Thank you!

WKWebView based apps crash in today's Xcode 16.4 iOS 18.5 simulator with messages including: "Library not loaded: /usr/lib/swift/libswiftWebKit.dylib" and of the form "/Users/yyy/Library/Developer/Xcode/DerivedData/zzz/Build/Products/Debug-iphonesimulator/libswiftWebKit.dylib' (no such file)"

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.

Canvas Previews (targeting macOS) in both Xcode 16.4 & Xcode 26 fail to load, when the project imports a Swift package that imports and uses WebKit. I'm on macOS 15.5. Tried also to bring minimum targets of both the project and the package to 15.0. I see that there are some work-arounds for iOS simulator but nothing for the Mac. Anyone facing the same problem?

Hello there, back in the old WebKit API there was the WKDownloadDelegate to handle download actions in WebViews. I was wondering how to handle download actions within the new WebKit in SwiftUI. Is there anything to use already or are there workarounds to handle downloads? Greetings, Thorben

I'm using the new Swifty WebView in 26.0 beta (17A5241e). Previously, I would wrap WKWebView in a ViewRepresentable and place it in the detail area of a NavigationSplitView. The page content correctly shrunk when the sidebar was opened. Now, the page content takes up the full width of the NavigationSplitView and the sidebar hovers over the page content with a translucent effect. This is in spite of setting .navigationSplitViewStyle(.balanced). Code below. I believe this is a problem with the new WebView not respecting size hints from parent views in the hierarchy. This is because if I replace the WebView with a centered Text view, it shifts over correctly when the sidebar is opened. struct OccludingNavSplitView: View { var body: some View { NavigationSplitView { Text("Sidebar") } detail: { WebView(url: URL(string: "https://www.google.com")!) } .navigationSplitViewStyle(.balanced) } } #Preview("Occluding sidebar") { OccludingNavSplitView() }

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!

I’m a developer working on a Safari Web Extension that’s distributed via the App Store and also tested locally through Xcode. I’m running into an issue that’s affecting my ability to debug errors reported to my Sentry error logging instance from production. The Problem When an error is thrown in one of my extension scripts (e.g., background.js, popup.js, or content.js), the error is sent to Sentry but the captured JavaScript error stack trace replaces the file paths with the webkit-masked-url://hidden placeholder like this: ReferenceError: Cannot access uninitialized variable. at ? (webkit-masked-url://hidden/:14677:28) at ? (webkit-masked-url://hidden/:16307:3) This happens consistently across both App Store builds and local Xcode runs. It prevents me from seeing which script the error came from or resolving the actual source code lines using uploaded source maps in Sentry. My Setup Safari Version: 18.5 (Stable on macOS) Distribution: App Store and local Xcode development Extension Type: Safari Web Extension Error Reporting: Sentry (@sentry/browser SDK) Bundler: Webpack with inline-source-map What I’ve Confirmed I can see the actual source files in Safari’s Web Inspector under the Sources tab when the extension is running. My source maps are uploaded to Sentry correctly and are associated with the matching release. Errors from Safari are being captured by Sentry, but the file URLs are masked, so stack traces cannot be resolved against my original source. My Question Is this behavior (masking file URLs in stack traces with webkit-masked-url://hidden/) intentional for Safari Web Extensions? If so, is there any supported method or workaround to allow exception stack traces to reveal the original script path (e.g., popup.js, background.js) so tools like Sentry or even console logs can point to real locations? I fully understand the privacy/security rationale behind the masking, but as the extension developer, this is making it extremely difficult to debug runtime issues in production. I’d really appreciate any insight into: Whether this masking is expected and permanent behavior If there are any entitlements, debug settings, or Info.plist keys that can alter this behavior for development or for trusted/own extensions If Apple recommends a different way to log extension errors that includes script name or source references Thanks in advance for your help! I’m happy to share more technical details or try out suggestions.

Hi all, I have a React web app that we use as a Progressive Web App (PWA). We currently: Use PWA Builder to package it for Android and iOS Host the app on a secure HTTPS URL Use Firebase Cloud Messaging (FCM) for push notifications (working on Android) However, on iOS, we are unable to get push notifications to work. I understand that PWAs on iOS have limited push support (Safari only, and not through WebView). So I explored using Capacitor, but: Capacitor can load a server.url pointing to our hosted app (great for reuse), but push notifications don’t work If we build the web app locally (npm run build) and embed it in the native iOS shell via Capacitor, push works We would prefer not to fully merge our authentication and main app UIs if avoidable Questions: Is there any approved way to enable push notifications in an iOS .ipa built from a hosted web app (URL) using PWA Builder? If not, is embedding the web assets locally the only Apple-approved way to get push support? Are there any best practices or native plugin recommendations (e.g., APNs or FCM) for handling push notifications in iOS app? Thanks in advance for any guidance. 🙏 Let me know if more technical details would help.
