title: Xcode 9 no longer copies xcassets into bundle target
body: <p>I updated to Xcode 9 and now when I build my bundle target, it no longer contains the xcasset images resources.</p>
  
  <p><strong>Setup:</strong></p>
  
  <ol>
  <li><p>The xcasset is associated with the target

  <li><p>The xcasset is included in the "Copy Bundle Resources" of the bundle target's Build Phases.</p></li>
  </ol>

  <p><strong>Result</strong></p>
  
  <p>The images within the xcassets are not present with the bundle product.

  <p>On a different machine with Xcode 8 I can build the same bundle target and the images within the TestCatalog are present.</p>
  
  <p>Note: the TestImage.png (that exists outside of any xcassets) is included as expected on Xcode 9.  This leads me to think that the issue is related to how xcassets are included.</p>
  
  <p>Thanks for any help.</p>
