title: xcode5 iOS Simulator failed to install the application
body: <p>Recently i installed X-Code 5 on my new Mac-mini, and created a iOS project with "Single View Application" template.(I haven't added any code). when i run the application i got the error "<strong>iOS Simulator failed to install the application.</strong>" The deployment target and Base SDK are set to iOS 7. </p>
  
  <p>The simulator screen is blank as [in this stack overflow question][1]  </p>
  
  <p>also the following Simulator menu options are not working.</p>
