title: Unity iOS build does not create any files
body: <p>I have created an XCode project through Unity in order to build for iOS, and the build succeeds with a few warnings, but there is nothing in the build folder.  It takes a few minutes to build, so it seems like it's doing something, but nothing is there. </p>
  
  <p>When I deleted the empty placeholder build folders that come with the Unity-generated XCode project just to see if it creates anything, the build folder does not even get created.  I have tried changing the bundle identifiers in Unity and on my provisioning profiles to match each other, but it hasn't helped.</p>
  
  <p>I am building for Generic iOS Device as opposed to an actual Device connected to my Mac.  Is that part of the issue?</p>
