Could not find library with name ”/usr/lib/swift/libswiftWebKit.dylib“
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?

PDF in WebView
Dear all, Is it possible to replace the default PDF background colour the 50% grey to any other colour while using the new WebView? Using the standard .background method on WebView does not appear to have any effect: WebView(pdfWebpage) .background(Color.blue) // no effect on the background of the PDF Thanks!

Issue with Copy Functionality in WKWebView Using Mac Catalyst
Hello, I am developing a Mac application via Mac Catalyst and encountering an issue with WKWebView. Specifically, I'm loading a webpage (e.g., https://translate.google.com) in WKWebView, but when I press the copy button on the page, the content doesn't actually copy to the clipboard. I've attempted modifying the UserAgent without any success. Here is the relevant part of my code: override func viewDidLoad() { super.viewDidLoad() let config = WKWebViewConfiguration() config.preferences = WKPreferences() config.defaultWebpagePreferences.preferredContentMode = .desktop let webView = WKWebView(frame: .zero, configuration: config) webView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(webView) webView.scrollView.showsVerticalScrollIndicator = false webView.backgroundColor = UIColor.white webView.scrollView.backgroundColor = UIColor.white webView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true webView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true webView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true webView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true if let url = URL(string: "https://translate.google.com") { let req = URLRequest(url: url) webView.load(req) } }

WKNavigationDelegate methods not getting called even though
Hi everyone, We work on a macOS plugin which then gets loaded into another application. I'm trying to load a webpage in that application through our plugin using a WKWebView & I set my class as the navigationDelegate for the same. I do not receive any callbacks for the WKNavigationDelegate methods. I have debugged & made sure that the navigationDelegate is actually set to my class. Here is a sample code of what I'm doing : [[NSApplication sharedApplication] runModalForWindow:self.mWindowController.window]; - (void)windowDidLoad { [super windowDidLoad]; [self.window makeKeyAndOrderFront:self]; [self.window orderFrontRegardless]; if (self.mLoadingView == nil) { self.mLoadingView = [[LoadingView alloc] initWithFrame:[[self.window contentView] frame]]; } [[self.window contentView] addSubview:self.mLoadingView]; [self.mLoadingView showLoadingView]; [self.window setLevel:NSMainMenuWindowLevel]; [self loadWebPage]; } -(void)loadWebPage { [self.mWKWebView setUIDelegate:self]; [self.mWKWebView setNavigationDelegate:self]; [self.mWKWebView stopLoading]; NSURL *lURL = [self samplePageURL]; WKNavigation *lNavigation = [self.mWKWebView loadRequest:[NSURLRequest requestWithURL:lURL]]; } - (void)webView:(WKWebView *)pWKWebView didFinishNavigation:(WKNavigation *)pNavigation { [self removeLoadingview]; [self.mWKWebView evaluateJavaScript:@"document.body.setAttribute('oncontextmenu', 'event.preventDefault();');" completionHandler:nil]; } I do not get any calls in the webView:didFinishNavigation: & I also tried other methods like webView:didStartProvisionalNavigation, webView:didFailProvisionalNavigation:withError: etc but did not receive any call in those either. Instead of runModalForWindow: if I use showWindow: on the mWindowController the webpage somehow loads but I still don't get any callbacks & so the loadingview subview is also present. The WKWebView is placed in a storyboard, and I have an IBOutlet connected to it in my class. Has anyone faced a similar issue or can point me to something I might be missing? All help is appreciated. Thanks in advance.

iOS/iPadOS 18+: Camera Video Recorded via Browser Appears Flipped or Upside Down
I'm encountering an issue with front camera video recordings via browser (Safari/Chrome) on devices running iOS/iPadOS 18 and above: On iPad, the recorded video appears upside down. On iPhone, the recorded video is rotated 90 degrees. The rear camera functions correctly without orientation issues. This problem seems specific to browser-based recordings, as the native Camera app records videos with the correct orientation. Has anyone else experienced this behavior? Is there a known workaround or fix? The preview while recording is fine, the recorded video is oriented incorrectly.

Assistance with Capturing WebView Snapshot in Broadcast Upload Extension Without Adding to View Hierarchy
Hello, I am currently developing a game streaming application using ReplayKit and Broadcast Upload Extension. I would like to ask for your assistance regarding capturing snapshots of a WKWebView in the upload extension without adding it to a visible view hierarchy. From my understanding, calling takeSnapshot(with:) on a WKWebView that is not added to the view hierarchy generally works for simple web pages. However, when it comes to more complex web content — such as animations or WebGL — the snapshot returns a blank or static image. I believe this is because rendering such content requires access to the GPU, which is not fully available when the web view is off-screen. That said, I’ve observed that certain apps are able to capture live animated web content inside their broadcast upload extensions, even when the main app is terminated. This suggests that the snapshot is not being generated by the main app or from a remote server — especially since the network activity confirms the content is served locally (via localhost or local IP). Given this, I believe there must be a way to achieve GPU-accelerated rendering for WKWebView directly within the upload extension context, without attaching it to the app's UI. I would greatly appreciate any guidance, APIs, or recommended techniques that could help me achieve this behavior correctly and within system limitations. Thank you in advance for your support. I look forward to your advice. Warm regards,

iOS 26 - WebKit in SwiftUI - Handle Downloads
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

Reader Mode for new WebView & WebPage APIs
I am curious if the new WebView and WebPage APIs have a way to programmatically set if the web page should be shown in Reader Mode like you could with SFSafariViewController. I did not see a way to do this, but I'm curious if I may be missing something.
