Previously working projects fail
I have a small example project that ran on both the simulator and a connected iPhone but now it and all other projects are failing with the same error. I am using Xcode 16.0 on MacOS Sonoma 14.6.1., iPhone 11 with iOS 18. Thank you in advance. The error is: Failed to resolve host network app id to config: bundleID: com.apple.WebKit.Networking instance ID: Optional([_EXExtensionInstanceIdentifier: 1163B5D2-09D3-4704-9564-61099502138B]) WebContent process (0x114018680) took 1.375772 seconds to launch GPU process (0x1140a0630) took 1.228457 seconds to launch Networking process (0x114034d00) took 1.426249 seconds to launch 0x105820a20 - [pageProxyID=7, webPageID=8, PID=34786] WebPageProxy::didFailProvisionalLoadForFrame: frameID=1, isMainFrame=1, domain=NSURLErrorDomain, code=-1200, isMainFrame=1, willInternallyHandleFailure=0 Message from debugger: killed Below is the code from one of the examples: import UIKit import WebKit class ViewController: UIViewController { let webView: WKWebView = { let prefs = WKWebpagePreferences() prefs.allowsContentJavaScript = true let configuration = WKWebViewConfiguration() configuration.defaultWebpagePreferences = prefs let webView = WKWebView(frame: .zero, configuration: configuration) return webView }() override func viewDidLoad() { super.viewDidLoad() view.addSubview(webView) guard let url = URL(string: "https://google.com") else { return } webView.load(URLRequest(url: url)) //evaluate JavaScript DispatchQueue.main.asyncAfter(deadline: .now()+5){ self.webView.evaluateJavaScript("document.body.innerHTML") { result, error in guard let html = result as?

Safari Extension state using declarative device management
So recently Intune add support for controlling safari web extension enablement using the new ddm configuration added in Macos 15, but unfortunately I can't make it work no matter what I try. On the destination machine I see the that a user declaration for safari extension has been created, but there is not details on which extension they applied and it seems faulty (See attachment) I have 2 questions: Has anyone managed to make it work? Is there a way to test this declaration like I can do with Mobile config by manually load it to the machine? Thank you.

Polylines do not stay on map
When I create a polyline and add it to the map, it will disappear if the map is moved. If I add a polygon or annotation, it remains on the map if the map is moved: const polyline = new mapkit.PolylineOverlay(path, { style: new mapkit.Style({ lineWidth: 5, strokeColor: '#007AFF', lineJoin: 'round', lineCap: 'round' }) }) map.addOverlay(polyline) // disappears if the map moves or zoom changes const polygon = new mapkit.PolygonOverlay(shapes, { style: new mapkit.Style({ fillRule: 'evenodd' }), enabled: false }) map.addOverlay(polygon) // remains on map when map moves or zoom changes Why is it inconsistent? How can I make the polyline stay until I explicitly remove it?

But keep me sign in function not works anymore after upgrade device to IOS 18. User need to enter credential every time after reopen the app. Is there any thing change in WKWebview in IOS 18?

SFSafariViewController not loading web pages on Xcode 16 Simulator with iOS 18
After updating Xcode to the latest version we observed that SFSafariViewController is not loading web pages on Xcode 16 Simulator with iOS 18, whenever it is presented the View Controller is empty (does not load any content) and the app freezes, but other screens that use WKWebView are working normally. Also, during tests on physical devices with iOS 18 it seems to work just fine, so it might be just a IDE version problem. Is anyone experiencing the same issue? If so, did anyone find a solution for it?

declarativeNetRequest.getMatchedRules() not working on iOS 18 Safari
declarativeNetRequest.getMatchedRules() gives us the below error: Error retrieving tabs or matched rules: – Error: Invalid call to declarativeNetRequest.getMatchedRules(). The 'activeTab' permission has not been granted by the user for the tab. We have added the "activeTab" permissions in the manifest (version 2). And in the device Safari extension settings we see that user has given permission as "allow".

IOS Safari support for WebTransport
We're developing a service that requires webtransport support in the browser. Currently, the only browser that doesn't provide support is the IOS version of Safari. Our current way forward for client use is to flag iphone and ipad as non compliant and recommend either desktop use or android. Is there any ballpark date as to when WebTransport will be included in IOS Safari (- webkit supports webtransport)?

FetchEvent.respondWith is terminated in 70 seconds in ServiceWorker
Hi, there. I am trying to use ServiceWorker on iPad to retry a request that has a communication error. However, I am having trouble with the process being terminated after 70 seconds. Occurs at least on iPadOS 17.6.1 and 16.3. The following is the service worker code to reproduce the problem: self.addEventListener('fetch', (event) => { if (event.request.url.includes('test.html')) { event.respondWith(longRunFetch()); } }); async function longRunFetch(request) { await new Promise(resolve => setTimeout(resolve, 75000)); return new Response('Fetch completed'); } When this code is executed on an iPad and a request is made to test.html, the service worker stops after about 70 seconds. When it stops, it falls back to the network request and the contents of test.html are displayed. The service worker thread appears to be killed and is unavailable until the browser is restarted. If timeout is set to 65000, 'Fetch completed' is displayed as expected. Why is the process terminated in 70 seconds? Is there any way to continue processing beyond 70 seconds?

WKWebView can not play audio with webrtc on iOS 18 and iPadOS 18
I am experiencing an issue with my app, which includes a WKWebView used for displaying and playing WebRTC content (audio and video). Everything works fine on macOS, but on iOS 18, while the video is displayed correctly, there is no sound. I am wondering if this could be related to privacy permissions on iOS. Could you please clarify if there are any specific privacy permissions I need to address? I would like to confirm: AVAudioSession.sharedInstance().setCategory requires any special configuration for WebRTC audio. Are there any particular settings needed for this? My setting codes are below: try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, policy: .longFormAudio) Do the JavaScript codes in the HTML file require any special handling to ensure WebRTC audio works properly on iOS? const audioRender = document.createElement('audio'); audioRender.id = 'xxxid'; audioRender.srcObject = streamSource; audioRender.autoplay = true; audioHolder.appendChild(audioRender); Does WKWebViewConfiguration need any specific parameter adjustments to ensure audio playback in WebRTC works as expected? let webViewConfiguration = WKWebViewConfiguration() let contentController = WKUserContentController() contentController.add(self, name: "***") webViewConfiguration.userContentController = contentController webViewConfiguration.allowsInlineMediaPlayback = true

TTS voices missing from web speech API in Safari since iOS 18
Web-apps which call speechSynthesis.getVoices() used to get a couple of good quality TTS voices which are still available in the iOS 18 simulator: com.apple.voice.compact.es-ES.Monica and com.apple.voice.compact.es-MX.Paulina Unfortunately on a real iPhone running iOS 18, these voices are not available, which is a regression since iOS 17 had them. The only Spanish voices start with the prefix com.apple.eloquence.es and are of worse quality.

WebAssembly wasm not able to load on Safari Web Extension
Hi, I am having issue with WebAssembly not able to load wasm file on Safari web extension. It is showing CompileError: Refused to create a WebAssembly object because 'unsafe-eval' or 'wasm-unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'wasm-unsafe-eval'". It was working fine 2 month ago, my original CPS is "script-src 'self' 'unsafe-eval'". But now it is not accepting 'unsafe-eval', I also tried 'wasm-unsafe-eval' did not work. Is there any changes on Safari browser regarding the CSP for WebAssenbly? Please let me know what CPS value will work. Here is the example code on how I load the WebAssembly wasm file. fetch('test_wasm_lib.wasm') .then(response => { if (!response.ok) throw new Error('Network response was not ok'); return response.arrayBuffer(); }) .then(bytes => WebAssembly.instantiate(bytes)) .then(results => { // Use your WebAssembly instance here console.log('load wasm success') }) .catch(error => { console.error('Error loading WASM:', error); });

ios 18.0 im stuck on lockscreen
Dear Apple Support Team, I hope this message finds you well. I am writing to express my frustration and seek assistance regarding an issue I am experiencing with my new iPhone 15 after updating to iOS 18.0. Since the update, my device has become unresponsive and is stuck on the lock screen. I have attempted multiple troubleshooting steps, including resetting and restoring my iPhone, but unfortunately, none of these actions have resolved the problem. Here are the specific steps I have taken: I performed a force restart of the device by following the appropriate button sequence. I attempted to restore the device using iTunes/Finder by putting it into recovery mode, but the issue persists. I have ensured that my device is charged and that I am using the original charging cable. Despite my efforts, my iPhone remains unresponsive, and I am unable to access any of its features. This situation is quite concerning, especially considering that I rely on my device for daily communication and tasks. I would greatly appreciate any guidance or solutions you could provide to help resolve this issue. If there are any further steps I should take or if I need to bring my device in for service, please let me know. Thank you for your attention to this matter. I look forward to your prompt response.
