Also facing the same issue when trying to run on iOS 14 using Xcode Version 13.2.1 (13C100) @available(iOS 15.0, *) @FocusState private var focusInstitution: Bool

Encountering same issue while testing iPad error handling. Unfortunately updating to 15.7 broke testing as well as iPad Pro model MM172CL/A "Airplane Mode" in settings no longer works since I need to use that feature in my tests as well.

xcode 15 Beta 6 iOS Simulators practically unresponsive. Tried on both iMac and MacBook Pro. Not viable to work with.

I have the same issue when using my intel based iMac and MacBook Pro. Haven't heard any confirmation but it might be intel based Macs that are affected.
