Simulator keeps crashing in Xcode 4.4

Question

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.

Answer 1

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.

Answer 2

我通过安装xcode 4.5和ios sdk 6解决了。现在一切正常。

Answer 3

I Had the same problem i just did following steps and it works fine

1) Reset your iPhone simulator

2) Clean Build your code

3) Restart your computer

Its works for me.

Answer 4

重新启动模拟器.....有时一些应用程序保留在内存中....否则重新安装它...一些数据可能已损坏... :)
