XCode 4.4 iOS 5.1 Simulator problems

Question

i updated my mac book to mountain lion and Xcode to the 4.4 version. In the pre version I had no problems with closing the iOS simulator and Xcode stopped automatically the building process but now if I close the iOS simulator the build process in Xcode is still running and I have to force quit Xcode because it freezes.

Does anyone recognize this bug, or can you help me to solve this problem?

Answer 1

作为一种解决方法，我注意到运行（⌘+ R）和Bulding（⌘+ B）产品成功启动了新的模拟器实例，尽管旧实例仍然处于冻结状态。

Answer 2

I just reverted to doing something I used to do when this started happening to me back in XCode 3.1 or something.

Press the STOP button in XCODE before you close or background the app in iOS SIMULATOR.

Then close the iOS SIMULATOR.
