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

• From the xCode 6 pull down menus, Xcode > Open Developer Tool > iOS Simulator (if you get a pop up error just dismiss it)
• Once in the Simulator go to Hardware > Device > Manage Devices.
• Delete everything listed under simulator.
• Reboot your machine.

After that, navigate back to Manage Devices in the simulator and click the plus to add back your simulators. Then the iOS 8 simulators will show up.
