The application that I'm working on uses WebKit. I'm facing a strange behavior in the app with iOS 17, in which errors are being reported only for this OS version. It is a SIGABRT error, but there is no relevant information on it to work on.

So I have a WKWebView with a loaded page. This page is playing an embedded Youtube video. The playback state is WKMediaPlaybackStatePlaying. All good. Then I click a link on the page (navigation jumps to a new page) and the video is no longer playing. No video or audio. The navigationDelegate calls -webView:didFinishNavigation: And my navigationDelegate call -requestMediaPlaybackStateWithCompletionHandler: on the webview from within -webView:didFinishNavigation: And in the completion handler of -requestMediaPlaybackStateWithCompletionHandler: the playback state is WKMediaPlaybackStatePlaying but nothing is playing because we are on a new page.... I even tried calling -requestMediaPlaybackStateWithCompletionHandler: after a delay but that doesn't seem to make a difference (even gave it a delay as long as 5 seconds)

I have the following situation: I am trying to access a page that I can only access after we have logged in with the Microsoft 2FA auth. I always got the same error "415 Unsupported Media Type" in the Safari browser. After I had deactivated "Block POP" in the Safari settings and set "Hide my IP" to OFF, everything worked fine in the Safari browser. Now I am trying the same thing in my app in the WebView. I have already tried this code: import UIKit import SafariServices class HorizonViewController: UIViewController, SFSafariViewControllerDelegate { override func viewDidLoad() { super.viewDidLoad() showWebPage() } func showWebPage() { if let url = URL(string: "https://myurl") { let safariVC = SFSafariViewController(url: url) safariVC.delegate = self self.present(safariVC, animated: true, completion: nil) } } // Optional: SafariViewController Delegate Methoden func safariViewControllerDidFinish(_ controller: SFSafariViewController) { // Wird aufgerufen, wenn der Benutzer den SafariViewController schließt controller.dismiss(animated: true, completion: nil) } // Sie können hier weitere Delegate-Methoden hinzufügen, falls Sie sie benötigen. } an also this code: import UIKit import WebKit class HorizonViewController: UIViewController, WKNavigationDelegate, WKUIDelegate { var webView: WKWebView! override func loadView() { // Erstellen einer Web-Konfiguration let webConfiguration = WKWebViewConfiguration() // Deaktivieren des Cross-Site-Trackings webConfiguration.websiteDataStore = WKWebsiteDataStore.nonPersistent() // Erstellen der WebView mit der obigen Konfiguration webView = WKWebView(frame: .zero, configuration: webConfiguration) webView.navigationDelegate = self webView.uiDelegate = self view = webView } override func viewDidLoad() { super.viewDidLoad() if let url = URL(string: "https://glavid.golav.lu/") { var request = URLRequest(url: url) request.setValue("application/json", forHTTPHeaderField: "Accept") webView.load(request) } } // MARK: - WKNavigationDelegate // Optional: Hier können Sie die Navigation im WebView steuern // MARK: - WKUIDelegate func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? { if navigationAction.targetFrame == nil { webView.load(navigationAction.request) } return nil } } Unfortunately, I get the same error 415 after the 2FA.

My app has a webview, when the user clicks on an item that is a dropdown list "select&gt;" element, it crashes !!!!! This happened immediatly after upgrading any device to iOS17 Any fixes??

I have a WKWebView that sets the UIDelegate: self.webView.UIDelegate = self; The following methods are never called when I right click in the WKWebView to being up a context menu: -(void)webView:(WKWebView*)webView contextMenuForElement:(WKContextMenuElementInfo*)elementInfo willCommitWithAnimator:(id <UIContextMenuInteractionCommitAnimating>)animator -(void)webView:(WKWebView*)webView contextMenuConfigurationForElement:(WKContextMenuElementInfo*)elementInfo completionHandler:(void (^)(UIContextMenuConfiguration * _Nullable configuration))completionHandler - (void)webView:(WKWebView *)webView contextMenuDidEndForElement:(WKContextMenuElementInfo *)elementInfo; This is from a Mac Catalyst app (I'm on macOS 14.0 23A344)

I created an WKWebView, but it can not load "https://www.baidu.com" and also it keeps calling decidePolicyForNavigationAction function it works well for other website @interface ViewController() @property (nonatomic, strong) WKWebView* webview; @end @implementation ViewController (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. self.webview = [[WKWebView alloc] initWithFrame:NSMakeRect(0, 0, 500, 500)]; [self.view addSubview:self.webview]; self.webview.navigationDelegate = self; NSURL* url = [NSURL URLWithString:@"https://www.baidu.com"]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; [self.webview loadRequest:request]; // [self.webview reload]; } (void)setRepresentedObject:(id)representedObject { [super setRepresentedObject:representedObject]; // Update the view, if already loaded. } (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction preferences:(WKWebpagePreferences *)preferences decisionHandler:(void (^)(WKNavigationActionPolicy, WKWebpagePreferences *))decisionHandler{ decisionHandler(WKNavigationActionPolicyAllow, preferences); }

Hi Folks, Our WebRTC based application has seen an increase in failed sessions after the iOS 17 update. After some debugging we noticed that on iPhone for all failure sessions the number of keyFramesDecoded is > 0 while the number of framesDecoded == 0. According to the WebRTC standard this should not be possible: "This is a subset of framesDecoded. framesDecoded - keyFramesDecoded gives you the number of delta frames decoded.", so this seems to be a bug in the Safari WebRTC implementation on iOS17.

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.....

iPhone 14 Pro + iOS 17.0.2. Cookies are not getting added to Web Requests On the above device model, cookies stored in WKWebCookieStore are not automatically added to web view requests. This bug is happening only after upgrading the device to iOS 17.0.2 on my iPhone 14 pro. Other devices with same OS version are not having this issues. Anyone has faced this issue and possible solve for this?

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 have a hybrid iOS app that continually is crashing, I have posted a crash report for this issue before. It appears to be happening when it is trying to save data to storage, it is taking all the data and attempting to convert a large object to a JSON string with the built in javascript Stringify method. Is there anything that sticks out to anyone? Original app name is redacted. Crash_Report.txt

I have a Mac Catalyst app configured like so: The root view controller on the window is a tripe split UISplitViewController. The secondary view controller in the Split View controller is a view controller that uses WKWebView. Load a website in the WKWebview that has a video. Expand the video to “Full screen” (on Mac Catalyst this is only “Full window” because the window does not enter full screen like AppKit apps do). The NSToolbar overlaps the “Full screen video.” On a triple Split View controller only the portions of the toolbar in the secondary and supplementary columns show through (the video actually covers the toolbar area in the “primary” column). The expected results: -For the video to cover the entire window including the NSToolbar. Actual results: The NSToolbar draw on top of the video. -- Anyone know of a workaround? I filed FB13229032

I'm using WKWebView in a Mac Catalyst app (not sure if using Catalyst makes a difference but it seems WKWebView doesn't get the "full" Mac version AppKit apps do so maybe it does). When a website has a video playing and if I click the button that I guess is a Picture in Picture button next to the "close" button the web kit process gets an unrecognized selector sent to instance exception. -[WebAVPlayerLayer startRedirectingVideoToLayer:forMode: <-- Unrecognized selector. In debugging mode at least my app doesn't crash the video continues to play and the WKWebview is unresponsive to user interaction. I have to force quit my app. -- I'm on Sonoma 14.0

I had a Mac app in the App Store but I have had to remove it since it stopped working in Sonoma. It will not load content in the WKWebView giving this error in the console.

As the title says, a random crash is happening for iOS 17.0.2, when the user clicks on simple text field in wkwebview, while device locked in AAC mode, was not able to trace out the pattern, I am attaching the screenshot of the crash log from Xcode Organizer Screenshot:-

hi Support Apple, The issue is loading advertisement of YouTube. The WKWebview cannot load the advertisement but SFSafariViewControler can load it. Please help.

Using registerDefaults to set userAgent with key "UesrAgent" is not work in Xcode 15

I want to support "Sign in with Apple" for my macOS application. Currently, I'm using WKWebview to support this. I'm able to provide a sign in for the current mac user correctly. But some users try to login with another apple ID, which has FIDO certified keys added as 2FA. Now my WKWebView shows this : But nothing happens when they click on "Continue". I think I need to create some kind of interface in my application for this case, but no clear idea. I can't see much articles for this use case with security keys. Anybody has any idea ?

My APP is hybrid architecture, I transferred my test phone to a new phone, userdefault will be transferred, but the local storage of the front-end will not be transferred. Both(userdefault&amp;local storage) will be transferred when my colleagues transfer their personal phones. My test case Same model mobile phone Mobile phones with the same OS version Switch from a small OS version to a phone with a large OS version Switch from large OS version to mobile phone with small OS version The first three items are userdefault will be transferred, but local storage will not be transferred. The fourth item is that you will be asked to upgrade the OS version when transferring. Does anyone know any relevant information? Or are there any settings enabled?
