I'm trying to buil a WatchKit App on my new Apple Watch 5 with WatchOS 6.1 from Xcode Beta 11.3 (same problem also with non-beta Xcode 11.2), but I can't install the app on the real device.
The simulator works just fine, but when I try to run it on the device it tells me that it can't install the app with this advanced details of the problem:

I tried both a stand alone WatchKit App and a Watch+Phone app. With the Watch+Phone app I can install it on my phone just fine, but then I still can't run the watchkit app target on my watch.
I'm using my personal AppleID account (not a paid one, not sure if that's needed to just test an app on my watch). In the signing and capabilities I checked "Automatically manage signing" and my AppleId as team.
I managed to work it out by unpairing and repairing my Apple Watch. Probably there was something wrong with the Trust setting on my watch and I wasn't able to make it re-appear the request.
