FBSOpenApplicationErrorDomain code =4 error

Question

When I\'m trying to run iOS application in Xcode 6 in iPhone 6 simulator, I\'m getting error Unable to run app in Simulator.

And error code is:

Answer 1

This problem probably started after we enabled background mode in our app.My solution :

1) Go to simulator
2) Hold cmd + shift
3) Tap 'H' key two times
4) Slide the application off to stop it running in the background.
5) Run again.

(Very tiring to have to repeat the above step each time I build and run)
