title: Xcode 10 seems to break com.apple.commcenter.coretelephony.xpc
body: <p>I have upgraded to <code>Xcode 10</code> on <code>High Sierra</code> and now the <a href="https://github.com/googleads/googleads-mobile-ios-examples/tree/master/Swift/admob/RewardedVideoExample" rel="noreferrer">Rewarded Ad example project</a> from AdMob complains that <code>com.apple.commcenter.coretelephony.xpc</code> is not working correctly.</p>
  
  <p>Is there a new entitlement that I have to enable? I am searching for hours without any clue.</p>
  
  <p><strong>UPDATE:</strong>
  This only happens from the simulator. On the device it works fine. They must have added a new restriction.</p>
