Can't install app to Watch after Catalina update

I had a working Watch up until the recent Catalina update, which broke Xcode as it didn't have support files for iPhone 11. I updated to Xcode 11.2 and now it compiles my app but when it tries to install to my Series 3 watch I get this error:

Has anyone else got a similar issue since the update?

My catalina update is still waiting for me to accept it, but I've run into the same issue just today.


It was working fine yesterday.

I've updated to Xcode 11.2.1 and still get this error. The Apple feedback assistant team think it's because my iPhone is not connected to my computer...

I have the same issue as you. Did you manage to get it working?


Edit:

Ok, I managed to get it working by connecting the iPhone to the Xcode via cable. Previously I tried to connect with iPhone and Apple Watch wirelessly. Seems to be working, but loading and connecting debugger to the watch is taking from 1minute upto 3-4 minutes :O
