Xcode beta 6 iOS 8: Simulator not working

Question

I cannot launch the simulator successfully. Once I launch the IOS Simulator this error appears:

\"Unable to boot the IOS Simulator.\"

Answer 1

1. Open Xcode 6 beta
2. Goto Window > Devices
3. Click on the little + sign at the bottom
4. Add (if missing) all the devices that you want, or delete and recreate if not working.
5. If anyone of the simulator is not working then you can delete it and then re-create it again in this menu.
