title: Document saved on iCloud Drive seems not to be downloaded on iOS
body: <p>I'll let the user save backup of his data using iCloud drive. That works good. But if I switch to another iCloud Drive enabled device, I can't read the file.</p>
  
  <p>I can see the backup file within the iCloud Drive App, but it's not downloaded, (it shows the "download from icloud symbol).</p>
  
  <p>Is it possible to force the download of all files available within the directory if the user wants to restore a backup?</p>
  
  <p>Using Swift 2 on iOS 8/9.</p>
