Not sure if you submitted the feedback, but the workaround for the moment is in the release notes. #Preview can’t reference symbols in Swift type extensions when they are defined in the same module as the Preview (110671628) Workaround: Revert to using PreviewProvider, or copy the implementation of the extension directly in to the #Preview itself or make it a global symbol

I believe this may be related to the issue defined in the release notes. #Preview can’t reference symbols in Swift type extensions when they are defined in the same module as the Preview (110671628) Workaround: Revert to using PreviewProvider, or copy the implementation of the extension directly in to the #Preview itself or make it a global symbol

This may be related to the issue in the release notes. After deleting an item, SwiftUI may attempt to reference the deleted content during the animation causing a crash. (109838173) Workaround: Explicitly save after a delete.

Thanks! That worked. I suspected I was overlooking something obvious, and it was that I forgot the context in Previews.
