title: Instruments > device grayed out
body: <p>I'm running an app on my iOS device but, in Instruments, that device is greyed out. </p>
  
  <p>This also means I can't attach the process (<a href="https://stackoverflow.com/questions/6348403/cant-launch-ios-app-with-instruments-on-device">Cant launch iOS app with Instruments on device</a>). Is it anything to do with my earlier question: <a href="https://stackoverflow.com/questions/28913537/instruments-profile-revoke-and-request">Instruments &gt; Profile - Revoke and request</a>  </p>
  
  <p>Xcode: 6.1.1
  iOS: 7.1.2</p>
  
  <p>Any idea why?</p>
