title: Simulator is not available error (Xcode 6.1)
body: <p>I am about to upload the latest version of my app to the App Store, however up until this point I haven't done a whole lot of testing on iOS 7.</p>
  
  <p>When I go to use the simulator, I am getting the error:</p>
  
  <blockquote>
    <p>iPhone 4S is not available: Please select a different device and try again.</p>
  </blockquote>
  
  <p>My deployment target is set correctly to 7.0.</p>
  
  <p>Has anyone experienced this error? Any solutions?</p>
