Hello, I'm implementing Sign In With Apple in a SwiftUI application (iOS 14, SwiftUI 2). I'm importing the AuthenticationServices framework. The app build successfully, and can run on an iOS device or simulator. But I cannot preview the view in the Preview / Canvas (it would be easier to design the view). Cannot find 'SignInWithAppleButton' in scope Any idea why? Thanks Axel PS: Xcode 12 beta 6, macOS Big Sur beta 5

Hello, I have a SwiftUI application with a Core Data model. This model contains some entities, with properties. The canvas is working as expected, showing the preview. But whenever I add a new entity, event without any property, the canvas fail to show the preview (event a basic view with only a text view in it). The error message is the following: Cannot preview in this file - The operation couldn't be completed. Transaction failed. Process failed to launch. I tried to clean my cache, the derived data folder, reset the simulators, etc. When I click on Diagnostics, here is the message: Error Domain=FBProcessExit Code=4 "The process crashed." UserInfo={NSLocalizedFailureReason=The process crashed., BSErrorCodeDescription=crash, NSUnderlyingError=0x600002f29dd0 {Error Domain=signal Code=4 "SIGILL(4)" UserInfo={NSLocalizedFailureReason=SIGILL(4)}}} RemoteHumanReadableError: The operation couldn’t be completed.
