title: xcodebuild install doesn't seem to work for iOS device
body: <p>I need to install my app to a device from a command line (for CI purposes). To that end i am using <code>xcodebuild install -scheme MyScheme -project Maps.xcodeproj CODE_SIGN_IDENTITY="iPhone Developer: me"  -destination 'platform=iOS,id=xxxxxxxx'</code></p>
  
  <p>When I run the command with the necessary keys (the scheme and the signing identity), the command completes successfully and reports "<code>** INSTALL SUCCEEDED **</code>", however, the app doesn't appear on the device. </p>
  
  <p>I have seen the third party apps that claim to install your apps on devices, however, since they use private features, I am reluctant to use them.</p>
