Same Issue here.
Tried everything,
unparing, restarting, etc ...
Developer mode is On on both iPhone and Watch.
The watch asked me if i wanna give my Mac Mini Access to it, tapped yes.
Everything is setup as before but the watch does not appear under devices as paired device to my iPhone as well in xCode as run destination.
I'm developing on watch since 2 years ago and something is not working in Xcode 15 as before.
The strange thing is that the watch appears twice in console app but when i hit "Start Streaming" no logs appears.
