I have an iOS project that I copied from another project and used the rename method to rename it.
If I leave the project open and close Xcode the next time I open Xcode it opens this project, but it is read and no files show up.
If I close the project (without closing Xcode) and then just open the project again using the recently used or directly, everything is fine.
How do I fix this?
I have the same problem. I'm running xcode 9.x.
I'm having the same problem in Xcode 13.1 with my .xcodeproj file in the project navigator. It always shows up in red with no other files in the project navigator when I open Xcode. If I then close the project, and re-open it from the "File > Open Recent..." menu, it displays normally, with any other files.
