title: "Signed resources have been added, removed, or modified" when running iOS app on device
body: <p>I have an app with an extension. Install and run works fine in the simulator, but after running my app from Xcode to the device once, on subsequent runs I get the following lines in the device log:</p>
  
  <p><code>Feb 22 16:10:02 Sams-iPad streaming_zip_conduit[7544] &lt;Warning&gt;: __dispatch_source_read_socket_block_invoke:203: Failed to install application at file:///var/mobile/Media/PublicStaging/Pinner.app_sparse.ipa/ : Error Domain=LaunchServicesError Code=0 "The operation couldn’t be completed.

  <p>Here's my code signing setup for the app:

  <p>And for the extension:

  <p>After cleaning the build folder, the app will then install again. This happens on two separate devices (iPad, iPhone).</p>
  
  <p>I am using CocoaPods - I've tried removing them and setting up the project again, no luck there.</p>
