问题
When ever I run my app in Xcode 4.4 the simulator fails to open, "iOS Simulator quit unexpectedly." It runs on perfectly on the device though.

I solved by installing xcode 4.5 and ios sdk 6. Now all work fine.
回答2:
You may have had a bad build on the Simulator, which is now messing things up.
- Clean your code
(Product > Clean in XCode) - Reset your simulator settings
(iOS Simulator menu > Reset Content and Settings)
That should do it.

Reboot the simulator ..... sometimes some apps remain in the memory.... Otherwise reinstall it ... some data could be corrupt... :)

I had the same issue on Lion. After upgrade to Mountain Lion I haven't such issue.
