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.

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

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.

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
