It's the "in reasonable time". In most cases there is some actual error, but XCode apparently can't figure out what the error is within a certain time limit. But my question is not about the fact that there sometimes is an underlying problem in the code but that this specific issue seems to show up much more often now since upgraded to XCode 15.

Thanks for sharing! Your solution just concluded a multi hour long search and debug for me.

The new NavigationStack in SwiftUI for iOS 16 doesn't seem to have this issue anymore.

I have the same issue in Beta 1, Beta 2 and Beta 3. Also, the animation going from View 2 to View 3 is somewhat weird.
