IOS 8 Simulator unable to boot

Question

When I try to run my app with Xcode 6 Beta 4 on the Simulator iOS 8.0 I always get this error:

Unable to boot the iOS Simulator

Answer 1

I found that removing and re-adding the simulator in Xcode 6 fixes the issue.

1. After opening xcode 6 open iOS simulator
2. Open hardware manage devices
3. Remove all the simulators and re-add them
