Hi all, I deployed a static site and two of my imgs are not appearing on some iPhones. It's not showing up on my iPhone 15 Pro but it's appearing on an iPhoneSE and androids. When I long click them, they actually show up in preview and can even open the images in a different tab, so they're just transparent. Does anyone have any idea why this is happening?

Hello, my radio streaming app worked well in iOS 17.2 and earlier but from iOS 17.4 streaming no longer works, what has changed? What do I have to do in my app? import UIKit import WebKit class ViewController: UIViewController, WKNavigationDelegate { @IBOutlet weak var mWebView: WKWebView! private let url: URL = URL(string: "https://mi web")! override func viewDidLoad() { super.viewDidLoad() let configuration = WKWebViewConfiguration() // Configurar preferencias de la página web let preferences = WKPreferences() preferences.javaScriptEnabled = true configuration.preferences = preferences mWebView.navigationDelegate = self mWebView.load(URLRequest(url: url)) } }

Dear Apple Community, I am writing to seek assistance with a challenge I've encountered regarding the playback of WebM video format in Safari. Despite various attempts and troubleshooting, I've been unable to successfully play WebM videos in Safari using the HTML5 video tag with provided Blob URLs. The videos, which are recorded in WebM format using browsers such as Chrome, fail to play in Safari, causing inconvenience for users who rely on this browser for their browsing needs. I understand that Safari may have certain limitations and compatibility issues with certain multimedia formats, but as WebM gains popularity as a widely used format for web-based videos, its support in Safari would greatly enhance the browsing experience for many users. I'm reaching out to inquire if there are any known solutions, workarounds, or plans to address this issue. Specifically, I've attempted to utilize the HTML5 video tag with Blob URLs to play WebM videos in Safari, but to no avail. If there are alternative methods or techniques that I may have overlooked, I would greatly appreciate any guidance or assistance in enabling playback of WebM videos in Safari. Ensuring cross-browser compatibility and seamless playback of multimedia content is crucial for providing a consistent and enjoyable user experience across different platforms and environments. Any insights or recommendations from the Apple community would be immensely helpful in resolving this issue. Thank you for your attention to this matter, and I look forward to your response. Sincerely, Umair Khan

My videos have stopped loading on canvas after the iOS 17.4 update. I tried partially loading the videos instead of loading them entirely and it works on safari but not on chrome. Any ideas on how I can fix this issue? What is the recommended way of loading videos on canvas for browsers on iOS?

How exactly am I supposed to implement the following delegate method of WKWebView? func webView(_ webView: WKWebView, showLockdownModeFirstUseMessage message: String, completionHandler: @escaping (WKDialogResult) -> Void) The problem: the delegate method is defined to be available since iOS 13. But "WKDialogResult" in the completion handler is declared to be available since iOS 16. So this is already very odd and probably a bug in the API declaration. When I make the delegate method available since iOS 16 (via @available (iOS 16.0,*)) then Xcode gives me an error stating that this method must be provides for iOS 14 and later. But when it is made available since iOS 14 (or 13), then I get the error that WKDialogResult is only available since iOS 16. So this looks like a big messy bug in the API declaration, or did I miss something here? It would not the first bug in the API declaration of the WKWebView where the availability is wrong (for example the property "upgradeKnownHostsToHTTPS" is declared to available since iOS 14.5, but in reality it is only available since iOS 16 and would crash when used under iOS 14.5)

I have created a new build for my Safari web extension and distrbuted it to test flight. Test Flight says I am using the correct version - but when I go to the Setting > Extensions in Safari and enable it - it still has the old version number. App Store showing the correct version is in testing Test Flight confirming said version number Safari with the incorrect version Any idea what I am doing wrong?

Is there any reference/documentation/discussion about the motivation for including the WKWebView loadSimulatedRequest() method? Is it intended to be used for testing? Page load performance enhancement? I'm wondering if there is a way to leverage its usage in our webview dependent app.

Safari is allowing users to create multiple passkeys despite setting the excludeCredentials in PublicKeyCredentialCreationOptions (https://developer.mozilla.org/en-US/docs/Web/API/CredentialsContainer/create#excludecredentials). I also included appidExclude(https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API/WebAuthn_extensions#appidexclude) but it was still allowing me to create multiple passkeys on the same iCloud account. This does not happen in other browsers. Can anyone point me to any documentation regarding this? Much appreciated https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API/WebAuthn_extensions#appidexclude https://developer.mozilla.org/en-US/docs/Web/API/CredentialsContainer/create#excludecredentials

Hi all, An app that until yesterday would take 1 second to render a list in the WKWebView is now taking over 3 minutes to load. No changes have been made to the app or the content that it is showing. I have tested on a device running 17.3, and performance has been acceptable, and then updated to the latest security fix (17.4.1) and now 3 minutes. Having read the release notes https://support.apple.com/en-us/HT214097 I cant see what would have affected either the processing of javascript or the rendering of content within the web view. My team is currently running all our apps that use a hosted WKWebView within it to ensure that they aren't affected, but this one app is now unusable and safety concern for the users (Airline Safety). Has anyone else experienced this or has a workaround - Sorry there are no logs (I have been scanning the device logs and nothing new is appearing - almost as if the operation is just dead locked).

Hi! I've faced with a problem while using input navigation arrows. When I focus the last field and then click on the down arrow - it takes me to the first field in the beginning of the screen

I'm trying to develop a Safari app extension and want to enable a persistent background page for it. I could find examples of how to enable it for Web extensions using manifest.json, but for App Extension it seems that I need to use Info.plist and I couldn't find any documentation on it. How can I use the background page?

Hello, I am currently developing an Angular application. In the application, there are labels containing "Name" above some input fields. If these inputs contain a "Name" label; (I should mention here that this problem is observed not only in the label tag, but also in the span and p tags) I think it suggests the names of the people in the contacts in the input field. If you open up that link in Safari, you can try that behavior. https://stackblitz.com/edit/stackblitz-starters-lvykt2?file=index.html

Good evening, I am having problems with my WebRTC application when an iPhone or Macbook is connected. This only happens when an iPhone or Macbook is connected, as tests with Windows or Android devices have shown no issues. As can be seen in the screenshot below, it appears that the datachannel is not initialised correctly. In fact, the webcam and microphone do not work even if permissions are given by the user, and messages and the remote webcam are not sent/shown. If I open chrome console on Windows, this is the error I get in the console Could you please help me investigate this problem. If you want, you can have full access to my application at https://www.fourmeet.it. I attach the functions that seem to be responsible for the problems: const configuration = { iceServers: [...turnServers, { urls: 'stun:stun.1und1.de:3478'}], iceTransportPolicy: 'relay' }; peerConection = new RTCPeerConnection(configuration); dataChannel = peerConection.createDataChannel("chat"); peerConection.ondatachannel = (event) => { const dataChannel = event.channel; dataChannel.onopen = () => { console.log("peer connection is ready to receive data channel messages"); }; dataChannel.onmessage = (event) => { console.log("message came from data channel"); const message = JSON.parse(event.data); ui.appendMessage(message); }; }; peerConection.onicecandidate = (event) => { console.log("geeting ice candidates from stun server"); if (event.candidate) { // send our ice candidates to other peer wss.sendDataUsingWebRTCSignaling({ connectedUserSocketId: connectedUserDetails.socketId, type: constants.webRTCSignaling.ICE_CANDIDATE, candidate: event.candidate, }); } }; peerConection.onconnectionstatechange = (event) => { if (peerConection.connectionState === "connected") { console.log("succesfully connected with other peer"); } }; const stringifiedMessage = JSON.stringify(message); if (dataChannel && dataChannel.readyState === 'open') { dataChannel.send(stringifiedMessage); } else { console.log('canale non aperto'); } };

Hi, I am creating a native application for the Vision Pro. I am looking to integrate a window with WebXR content that can open an immersive space. I am able to do this from Safari and using a SFSafariViewController, however, I would like to use WKWebView inside my native application to do something similar (as this does not open an additional Safari window before allowing WebXR content). It seems in this current version, the WKWebView does not support WebXR? Is this true or is there any additional preferences that I need to add to enable this in this component.
