We're seeing the same, no workarounds yet. Reported: FB13214392

Found a simple workaround with SwiftUI: Applying a clipShape appears to bring the layer under control. You'll also need to set the width as after applying the clipShape, it will still fill the width. SignInWithAppleButton( .continue, onRequest: { request in request.requestedScopes = [.email] }, onCompletion: { result in // Whatever... } ) .clipShape(RoundedRectangle(cornerRadius: 4, style: .continuous)) // Workaround here... .frame(width: 300) // ...and here

We're seeing the same issue too. Xcode 16.3 iOS 18.4

Sadly it's not just Xcode 26 beta 4. I think the issue is more with Tahoe Beta 4 than with Xcode? I have the same issue with beta 3 and Xcode 16.4. A workaround so far appears to be to use previews on device.
