title: Saving an iCloud Drive security scoped URL on iOS (UIDocumentPickerViewController)
body: <p>I'm trying to save the security scoped URL returned from iCloud document picker (UIDocumentPickerViewController)</p>
  
  <p>The documentation states:</p>
  
  <blockquote>
    <p>If the URL is not a ubiquitous URL, save a bookmark to the file using
    the
    bookmarkDataWithOptions:includingResourceValuesForKeys:relativeToURL:error:
    method and passing in the NSURLBookmarkCreationWithSecurityScope
    option. Calling this method creates a bookmark containing a
    security-scoped URL that you can use to open the file without further
    user intervention.</p>
  </blockquote>
  
  <p>However, the compiler says that NSURLBookmarkCreationWithSecurityScope is not supported on iOS.</p>
  
  <p>Anyone know what's going on here....?</p>
