Environment
• Device: iOS 26 Developer Beta 5 (23A5308g) • Xcode: 16.3
Short description
The app crashes the moment the user tries to long-press to select text inside a WKWebView, double-tap an image with Text (magnifier appears)
The exception is CALayer position contains NaN. frame = (nan,0;0,48) chorPoint=(inf, 0) and it is thrown in the UI process.
Build & run any project that hosts a WKWebView. Inject the following CSS via script (this is what we do to suppress the native callout menu):
WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.bounds
configuration:[WKWebViewConfiguration new]];
NSString *js =
@"document.documentElement.style.webkitUserSelect='none';"
"document.documentElement.style.webkitTouchCallout='none';";
[webView evaluateJavaScript:js completionHandler:nil];
[self.view addSubview:webView];
