I'm having problems with testing my app on real device. I have register all what I need to try my app on real device and when I tried to compalie it I got error telling me that i'm missing SwiftDataContainerSingletone.xcodeproj. The thing is I can compile and run in simulator but when I try on real device i get that error. some file appeared in my project.
