Are you only receiving this error for this particular project? If it's only this project, try changing the bundle ID and running again. – etayluz Aug 31 '16 at 05:33

Sounds like you need to delete derived data. Go to Window->Project->Select Your Project->Press Delete button (to delete derived data).
Now run simulator and hopefully that error should disappear.

Gotcha. Did you try to reset the contents and settings of the simulator? Try to 1. Clean build (SHIFT-CMD-K) 2. Reset contents and settings of simulator 3. Delete Derived Data 4. Build and run – etayluz Aug 31 '16 at 05:30
