I've updated the app for watchOS 2 using the built in suggestion with Xcode 7 when you first build it. I've changed all the necessary code so there's no errors or warnings but I can't seem to run either the containing app or the watch app in the simulator; they never launch but they do copy over to the simulators.
Is there a new scheme I should be using? I'm using the previous scheme for the main watch app which now automatically lets you choose between running the iPhone 6 simulator with either the 38mm or 42mm watch simulator.
