i have tried to install a simple App with 3 Buttons on my Apple Smartwatch 4 44m watchOS 5.3. The Smartphone is the Iphone 8 IOS 12.4.
On the simulator all is working fine, but on the real device following Error occurs at installing the WatchApp.

Maybe its because i cant choose watchOS 5.3 as destination build. I can only choose IOS 12.2 and watchOS 5.2. I dont know, ived tried lower versions, same error. On the simulator i can build the 5.2 watchOS on the 5.3 simulator.
You guys have some Ideas?
Thanks for help
