title: Xcode version unable to install the application on ios simulator
body: <p>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</p>
