When I try to run the Xcode simulator I get the error 'Stop “(null)”?'


Getting this as well with Xcode 7.

I've been following these simple steps to avoid seeing the error:

  1. Build your app.
  2. Run your app.

Annoying, and not a solution, but I think this is a bug within Xcode 7.


Completely quitting Xcode 7 and reloading resolved the simulator is already running it for me.


I got this error too, and building and then running the app (cmd+b ; cmd+r) solved the problem.
