title: How to list Shared Photo Stream Albums with PhotoKit
body: <p>I can obtain a list of Photo Albums created on the device with <code>PHFetchResult *results = [PHCollectionList fetchTopLevelUserCollectionsWithOptions:nil];</code></p>
  
  <p>I imagine there must be a similar way to obtain Shared Photo Streams Albums (or as I think they may be called now "iCloud Photo Sharing Albums"), but for the life of me...can't figure it out. Has anyone solved this problem?</p>
