Xcode版本无法在ios模拟器上安装应用程序

Question

I just upgraded my mac os from mountion lion to mavericks version 10.9.3 . In mountion lion i used Xcode 5.1 with ios simulator 7.1, 7.0 , 6.0 and 6.1 . I had a back up this xcode 5.1,which i installed to new mavericks version. Now if i run the project using the ios simulator 7.1 ,it shows iOS Simulator failed to install the application. Does it have anything to do with Xcode versions installed for the os versions

Answer 1

Reset your simulator like this:

Force Quit the simulator in the Activity Monitor.

U can try also remove the simulator ( link ) and re-install it
