On a MBP with Catalina.
When using Xcode 12 (any release), and open a SwiftUI app (absolutely basic one, just a say hello), I get the usual list of simulators.
If I open the same app with any Xcode below 12 (e.g 11.6, 11.5), I do not see any simulator in the list.
Any other app (SwiftUI or pure Swift) has no problem.
I tried to add simulators, could not get it done.
What could be corrupted in the SwiftUI app ?
