CoreSimulator is attempting to unload a stale CoreSimulatorService job.

After build when AppCode attempts to launch the iOS simulator I encounter this error.  It even occurs on the latest 3.4 EAP.   I've tried uninstalling and reinstalling all the simulators but that didn't help.

Looks like you recently renamed Xcode.app to XCode.app (or vice versa), and that confuses the simulator service. Please try renaming it back or rebooting.

Ok so the name of the bundle was Xcode.app, I renamed it to XCode.app and rebooted.  Got the same error.  I then renamed it back to Xcode.app and rebooted and everything is working now.   Thanks!
