I also filed a feedback report. Though, now answer yet (FB9037331). There are numerous questions with the same error but still none of them with a helpful answer. I completely reinstalled macOS, Xcode and so on. Tested on two different macbooks, two different devices, and signed with two different accounts. No chance. Even tried with Project Files provided by Apple (SwiftUI tutorial). - https://developer.apple.com/tutorials/swiftui/building-lists-and-navigation Nothing, absolutely nothing helped

I filed a feedback with diagnostics and sufficient descriptions on it some while ago (Mar 9, 2021 at 11:08 PM – FB9037331). Still no answer. It is extremely frustrating and a timely answer would be really helpful now!

I reported a bug to apple with the following feedback ID: FB9037331.

Having the same problem with Xcode 12.4 (12D4e) and iPad Pro 4th Gen. iOS 14.3 with all my projects including the files provided by a Apple SwiftUI Tutorial (https://developer.apple.com/tutorials/swiftui/handling-user-input). I would appreciate help a lot

Still experiencing the same problem with Xcode 12.4 with macOS Big Sur v11.2.1 and iPad Pro iOS 14.3. An update on this would be really nice!
