Is there any document or link is available or support for the same

Problems when connecting Bluetooth speakers on iOS devices. When trying to use the Web Speech Api -(Text-To-Speech) in safari immediately after connecting to a Bluetooth speaker, it playing the sound using the phone's speakers instead of the connected Bluetooth speaker's. Then, when I summon Siri and briefly use the voice function, the Web Speech API in the web browser uses the Bluetooth speaker, and it works. It seems that there may be some kind of limitation or issue when switching between Bluetooth devices and voice apis.

I built a web application that is designed to be run from my application bundle by using webView.loadFileURL(htmlFile, allowingReadAccessTo: projectFolder) on a WKWebView. Inside of the site's folder is a directory of svg images (from the ionicons project). At runtime the code tries to load one of those images using: req = fetch(url).then((rsp) => { if (rsp.ok) { return rsp.text().then((svgContent) => { if (svgContent && sanitize !== false) { svgContent = validateContent(svgContent); } (code from the ionicons project). The rsp.ok check simply examines the response to the fetch request to see if the status code is in the range 200-299. For the "file://" URL, however Safari on both MacOS and iOS returns 0 in the status. In spite of that 0, however the request has succeeded and the browser has the content of the file. If I modify the code to ignore rsp.ok the following call accessing rsp.text() succeeds. I'm not sure what the expectations are for a file:// URL passed through fetch. Is the 0 status code a bug in Webkit or Safari, or is it an expected result for a file:// URL and the code making the fetch request needs work?

I have the following lines of code in our app: @objc convenience init(webView: WKWebView, delegate: SomeDelegate, navigationDelegate: WKNavigationDelegate) { self.webView = webView self.webView.makeInspectable() self.webView.navigationDelegate = navigationDelegate self.webView.uiDelegate = self self.webView.configuration.suppressesIncrementalRendering = true self.webView.configuration.userContentController.add(weakSelf ?? self, name: "handlerOne") self.webView.configuration.userContentController.add(weakSelf ?? self, name: "handlerTwo") injectUserScripts() // Injects WKUserScripts into the webView.configuration.userContentController } My JS script looks as follows: (function() { addEventListener('mousedown', function() { window.webkit.messageHandlers.handlerOne.postMessage('WKUserScriptMouseDown'); }, true); })(); if (MyApp.getProperty("os") != null) { window.webkit.messageHandlers.handlerTwo.postMessage(url); } else { console.log(url); // non-mobile browser (for testing) } However I keep seeing an error in my Safari debugger: TypeError: undefined is not an object (evaluating 'window.webkit.messageHandlers.handlerOne') TypeError: undefined is not an object (evaluating 'window.webkit.messageHandlers.handlerTwo')

Hi guys, I'm a XR Developer, lately making a lot of web ar apps, I'm having an issue with iOS 17 at least on my iphone 14 Pro where the sound comes out of the call speaker, resulting very very low volume, sometimes I'm not sure how if I lock the phone and move it when I unlock it and go back to the webapp the sound it normal, loud and coming out of the media speakers. How I used to do this is my "start button" I unmute a play and pause it, and with this I used to be able to play later sounds of videos on the browser. Did something change with the last iOS 17 update? Is there a workaround for this? In the end what I want is be able to play sounds and videos on the web browser... This is a tag of a project that was working fine before the 17 update: And this is what I do on the start button: video.muted = false; video.play(); video.pause(); Help would be appreciated since I'm in the middle of deployment, thanks in advance

Javascript is being executed while using UI and WK WebView. However, since iOS 17.0.3, the WTFCrashWithInfoImpl issue has been posted in CrashReport, and it has been determined that Javascript is not supported in WebView for certain users. I wonder if there has been a fix in JavascriptCore.

window.getSelection().getRangeAt(0) is giving indexSizeError after selecting text from wkwebview in iOS 17. We are using evaluateJavascript functions for interactions. This was working fine in earlier versions. This problem is seen since the recent iOS 17 upgrade.

Hi, I'm using MediaRecorder for screen recording of canvas , along with audio. simplified code to implement screen recorder //intialise stream const canvas = document.querySelector('.main-canvas'); const stream = await navigator.mediaDevices.getUserMedia({ audio: true }); for (let track of canvas.captureStream().getTracks()) { stream.addTrack(track); } recorder = new MediaRecorder(stream); chunks = []; recorder.ondataavailable = ({ data }) => { if (data) chunks.push(data); }; recorder.start(); recorder.onstop = () => { const videoBlob = new Blob(chunks, { type: 'video/mp4' }); chunks = [] //stop mic access after use try{ for (let track of stream.getTracks()) { track?.stop(); } }catch(e){} return videoBlob; } so when i call recorder.stop() , the recorder.onstop method is not getting called sometimes randomly. And also in case when recorder.onstop is not called , recorder.ondataavailable is not called even a single time,So it returns empty Blob output. This only occurs in iOS 15 device's , it occurs randomly 40% of the times. Is there any workaround for this, or what is cause of this issue? Thanks in advance

In iOS16.4 the push notifications on progressive web apps are working but they didn’t have any sound while they appear. is this a bug or is there any way to enable the sound on push notifications on web apps ?

When use jsCore, The error reporting location is where JS communicates with Native, and the stack does not contain any valid information. Anyone konws what's the problem.....

Does webkit have a way to display a smart banner for a home screen web app similar to how a smart banner can be displayed for native apps? I recently noticed (10/23) that Twitter showed a smart banner encouraging Home Screen web app on my Mac running Sonoma. How is this done?

I randomly get this crash in my webview application when loading data. There is no pattern to it, it can happen in all areas where images are being loaded into vram. Here is the error: 2023-09-16 19:57:55.404378+0200 Bluelife[3284:194440] [Process x10d004350 - [PID=3445] WebProcessProxy: :didClose: (web process 0 crash) 2023-09-16 19:57:55.404500+0200 Bluelife3284:194440] [Process] 0x10d004350 - [PID=3445 WebProcessProxy::processDidTerminate0rFailedToLaunch: reason=Crash 2023-09-16 19:57:55.404579+0200 Bluelife[3284:194440] [ProcessSuspension] 0x10c01dfe - ProcessAssertion: Failed to acquire RBS Background assertion 'XPCConnectionTerminationWatchdog' for process because PID 0 is invalid 2023-09-16 19:57:55.410251+0200 Bluelife[3284:194440] [Process] 0x130856218 - [pageProxyID=14, webPageID=15, PID=3445] WebPageProxy: :processDidTerminate: (pid 3445), reason=Crash 2023-09-16 19:57:55.411392+0200 Bluelife[3284:211863] [ProcessSuspension] 0x10c01dfe - ProcessAssertion::acquireSync Failed to acquire RBS assertion 'XPCConnectionTerminationWatchdog' for process with PID=0, error: (null) 2023-09-16 19:57:55.424321+0200 Bluelife[3284:194440] [Loading] 0x130856218 - [pageProxID=14, webPageID=15, PID=3445] WebPageProxy::dispatchProcessDidTerminate: reason=Crash

When rendering 2 'div' components with 'display:flex' placed on top of each other, the preceding one sometimes comes up. The 'position:absolute' has been set and the second 'div' component is being generated after the first one. However, when inspecting the iOS webview in Safari, I enable-disable the 'display:flex' property, everything starts working again. This is possibly a bug in the layout engine. I tried the same process in iOS 16.4 and there are no issues at all.

Hello. I'm trying to stop my webview from asking for mic permission every time it runs, as I already handle it out in the application. This is the code I use, but it doesn't seem to run the code for the permission at all (tried printing and debugging, and it doesn't go into it at all). I am using visionOs if that makes a difference. Are there any alternative solutions to this? import SwiftUI import WebKit import AVFAudio struct WebView: UIViewRepresentable { let urlString: String func makeUIView(context: Context) -> WKWebView { let webView = WKWebView() webView.navigationDelegate = context.coordinator if let url = URL(string: urlString) { let request = URLRequest(url: url) webView.load(request) } return webView } func updateUIView(_ uiView: WKWebView, context: Context) {} func makeCoordinator() -> Coordinator { Coordinator() } class Coordinator: NSObject, WKUIDelegate, WKNavigationDelegate { // Handle media capture permissions func webView(_ webView: WKWebView, decideMediaCapturePermissionsFor origin: WKSecurityOrigin, initiatedBy frame: WKFrameInfo, type: WKMediaCaptureType) async -> WKPermissionDecision { return .grant } // Handle URL authentication challenges func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) { let username = "user" let password = "password" let credential = URLCredential(user: username, password: password, persistence: .forSession) completionHandler(.useCredential, credential) } } } struct AssistantView: View { @Environment(\.dismissWindow) private var dismissWindow var body: some View { WebView(urlString: "https://somelink.com/") .edgesIgnoringSafeArea(.all) .frame(width: 500, height: 800) } }

We have observed that safari / IOS WKWebView waits for ~250 renderable bytes before it starts to render HTML as received in the browser. This is different from the behaviour in chrome / Firefox where they start to render the content as soon as the first byte is available. We wanted to know if there’s a way to stop this behaviour, to bring parity across the two browsers. Also is there any official doc / announcement establishing this limit of ~250 characters which we’ve found experimentally. Details of our experiment: We created a simple HTTP Server In python that: Emits a stream of (100) characters Sleeps for 3 seconds Emits some more characters You can find the experiment code towards the end of the post The ideal behaviour (which we observed in chrome) is that the content should be rendered progressively. Implying that the 100 characters before the .sleep() should be rendered immediately. This should be followed by a gap of 3 seconds, and then the rest of the characters are displayed. You can see this behaviour where I reload the page: https://drive.google.com/file/d/1JD_ZbghX3OOz_CpSR2iGn_Se7_2HDRTw/view?usp=sharing The text "Before Sleep" followed by a line of 100 dashes is the content before .sleep() which appears immediately. The text “After Sleep” apears after a time of 3 seconds which is the desired behaviour. In safari however, all of the content appears at once after 3 seconds, instead of being rendered progressively as seen here when I reload the page : https://drive.google.com/file/d/1RiD7eFuwGYL5lGIcU1CF2gcpoSysHJ9C/view?usp=sharing However if we increase the number of characters emitted before the .sleep() to ~250 (256 to be exact) safari behaves similar to chrome and the content appears progressively. You can see this here on page reload : https://drive.google.com/file/d/1JlHFbZPdFuIiaAlkgYCWo61amBIysKL1/view?usp=sharing We found this value of ~250 experimentally via hit and trial. Not only rendering, we also found this delaying the execution of external .js (that is present in a separate .js file embedded via tag). To prove this, I added a simple console.log(performance.now()) at the top of the .js file (outside of any function). In safari with artificially inserted ~260 extra bytes this log was printed at ~1 - 1.5 secs. However without the extra bytes this log came at ~3 - 4 seconds. This gap corresponds to the time taken to make rest of the page ready. Note that embedded .js present in the HTML was not affected by this. Wondering if other’s have faced the same problem and if there's an official doc stating this limit / any workarounds. Python HTTP Server code that we executed for our experiment from http.server import BaseHTTPRequestHandler, HTTPServer import time import sys class handler(BaseHTTPRequestHandler): def do_GET(self): self.send_response(200) self.send_header('Content-type','text/html') self.end_headers() self.flush_headers() # Content before .sleep() message = f' <!DOCTYPE html> \ <html lang="en"> \ <head> \ <meta charset="UTF-8"> \ <title></title> \ </head> \ <body> \ ' self.wfile.write(bytes(message, "utf8")) self.wfile.flush() beforeSleep = 'Before Sleep' self.wfile.write(bytes(beforeSleep, "utf8")) self.wfile.flush() lineBreak = '<br/>' self.wfile.write(bytes(lineBreak, "utf8")) self.wfile.flush() blankChar = "-" fillerString = ""; for x in range(260): fillerString = fillerString + blankChar self.wfile.write(bytes(fillerString, "utf8")) # Sleep for 3 seconds time.sleep(3) self.wfile.write(bytes(lineBreak, "utf8")) self.wfile.flush() # Content after .sleep() which should be rendered progressively afterSleep = "After Sleep" self.wfile.write(bytes(afterSleep, "utf8")) self.wfile.flush() with HTTPServer(('', 8000), handler) as server: server.serve_forever()```

Introduction We load a saved web archive (NSData) into a WKWebView instance using following method: [self.webView loadData: archive MIMEType:@"application/x-webarchive" characterEncodingName:@"" baseURL:baseURL]; We also have some custom scripts injected safely into the web view using following snippet WKUserScript *userScript = [[WKUserScript alloc] initWithSource:<jsfilename> injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:onMainFrame]; [webview.configuration.userContentController addUserScript:userScript]; Things work fine till here. Observation When I get the call from Javascript Layer to the native iOS Layer via: -[CustomWebViewController userContentController:didReceiveScriptMessage:] the value message.frameInfo.request.URL.absoluteString is "about:blank" Question Is there any way to get the original baseURL back here? Alternatives Considered: Store the baseUrl in an instance variable and use it here but since we are using this url to determine if the request is coming from valid domains, having a url from this method will be most credible. We are looking a way to piggyback this info (baseURL domain) to our web archive at the time of loading it in webView and extract that from the -[CustomWebViewController userContentController:didReceiveScriptMessage:] method Any help will be much appreciated.

Hello I have a webrtc-based web app that is loaded inside a WKWebView. The web app gets loaded just fine in our iOS App running WKWebView on an iPad with iOS 15.1. We are using the exact same app, built for Mac Catalyst. However, on the Mac version, the web app gets loaded but the RTCPeerConnection object is undefined.. Meaning that our web app assumes that WebRTC is not available in that browser. Isn't the native app supposed to work the exact same on iOS and MacOS? Is the Mac version of WKWebView more limited than its iOS counterpart ? Is there any resource that states exactly what is supported in WKWebview in each platform? Thanks

Hi, I am trying out push notification for IOS 16.4 beta Simulator using Xcode 14.3 beta (14E5197f). Inside my JS code I have the following: Notification.requestPermission((permission) => { console.log(permission); }).catch((error) => { deviceNotSupported(); }); } Unfortunately "permission" always returns "denied". Please kindly assist

I ran a series of CPU-intensive tests, with code written in JavaScript on my iPad. I can execute the JavaScript code using either JavaScriptCore, or by using a WkWebView and making it load and execute the JavaScript. I found that JavaScriptCore is 12 to 15 times slower than WKWebView (18.3 s instead of 1.1 s). That seems huge. Is there any way to speed it up? Is there any reason why it's so slow? While we're at it, are there differences between the WebAssembly engine in JavaScriptCore and the one in WkWebView?
