Yeah I am seeing this too.

Thanks!!

I found it here: https://developer.apple.com/documentation/swiftui/building-a-document-based-app-using-swiftdata/

Do you need to do something in your apps to support Stage Manager?

It seems my error is only occurring with the SwiftUI view has an @FocusState variable.

I had that error for a while and removing the cache helped but then I got a new error: MessageSendFailure: Message send failure for update ================================== |  RemoteHumanReadableError: The operation couldn’t be completed. XPC error received on message reply handler |   |  BSServiceConnectionErrorDomain (3): |  ==NSLocalizedFailureReason: XPC error received on message reply handler |  ==BSErrorCodeDescription: OperationFailed

okay I will grab the GM -- thanks.

I got a crash alert this time: Process: Xcode [640] Path: /Applications/Xcode.app/Contents/MacOS/Xcode Identifier: Xcode Version: 12.0 (17219) Build Info: IDEFrameworks-17219000000000000~2 (12A7209) App Item ID: 497799835 App External ID: 837639917 Code Type: X86-64 (Native) Parent Process: ???

I had that for a few minutes and suddenly it started working. I think CharacterSelectionIntent.swift is generated by Xcode based on the Intents definition file but it takes sometime to generate, especially on a slower mac.

I am seeing this error on a device as well.

My widget appears in the simulator but if I try to add it with the widgets list, it doesn’t appear in that list.

I'm interested in this as well.
