title: Can't ionic cordova run ios
body: <p>I've been trying to resolve an issue deploying my app to an ios device for several months to no avail.  I can deploy to Android with no issues but not and iOS device.</p>
  <p>One thing I noticed is when I created a new app I can deploy to iOS until I implement facebook authentication.    At any rate, here is the below error message when I try to deploy to an iOS device by plugging the phone into my MAC and running '<code>ionic cordova run ios</code>'.</p>
