I am on MacOS 10.15.7 with Xcode 12.4 and I am facing the same problem.
Seems to be related to debugging - unfortunately it also applies to the Simulator in my case.
This is pretty unacceptable for a 'professional tool' I have to say. I need to get work done (which involves debugging in my case!)
Do I need to upgrade to Big Sur? (which probably keeps me busy for another day).
Downgrade to 12.2? (Really?!!)
What is the quickest way out of it - given I need latest SwiftUI libraries on iOS?
(and I guess this is rhetorical question as nobody from Apple seems to care?)

This still seems to be a problem - also on iPad on 14.6 with TrackPad control (MagicKeyboard) and Catalyst on Mac OS 11.4. It works on the iPad Simulator though...
// Never use the cellular interface
let tcp_params = NWParameters.tcp
