I've out from the nothing, two days ago my production computer started giving me issues with Xcode being the only one opened. BigSur 11.2.1, Xcode 12.4. Cleaned and reinstalled Xcode, still the same. I'm working with a simulator but even if it is closed also hangs. help asap.
Xcode 12.4 (Not Responding)
Same problem for me
@Fabio97, What's your machine? like a new M1 or old an MacBook?
@Fabio97, did you tried to unlink your iPhone? Go to window -> Devices and Simulators and just make that clear.
Running Xcode build 12D4e on macOS Big Sur 11.2.3 on 16" MacBook Pro Intel. Started to hang simply by scrolling through text. Rebooted machine. Still a problem. Has become unusable.
