How to run Watch App in XCode

I created a watch app, following Apple's guide lines, but not sure how to run it in the simulator.

When I select the Watch App scheme and run it, the iPhone simulator appears, and I can see WatchKit extension running, dumbing some logs 

2014-11-19 13:28:56.991 WatchApp WatchKit Extension[61833:6371439] <WatchApp_WatchKit_Extension.InterfaceController: 0x7b652010> init
2014-11-19 13:28:56.992 WatchApp WatchKit Extension[61833:6371439] <WatchApp_WatchKit_Extension.InterfaceController: 0x7b652010> will activate

But nothing happens on the simulator's screen.

Solution

  • What you run your WatchKit extension, you need to go to Hardware > External Displays and select an Apple Watch (there are two sizes, either works).

    enter image description here

    After this, you can make changes to your code in Xcode and run it, and the changes will be reflected in the WatchKit simulator without you having to mess with enabling the simulator again.
