I've been experiencing very random behavior when trying to launch my watchOS 1 app in the simulator. Sometimes it shows up, sometimes it doesn't even install and nothing happens, sometimes i got an activity indicator running forever. I reinstall, i "reset content and settings" the simulators, randomly, and most of the time i need to retry 10 combinations to get one success.
Now, since i'm using on Apple's IDE and Apple's SDK, running Apple's simulator on Apple's hardware, i'm thinking maybe there's AT LEAST one procedure to have the thing work 50% of the time ?
