title: Copy written billion+ pixel image to Photos?
body: <p>My app is successfully writing multi-gigapixel images (many billions of pixels per image).</p>
  <p>Is there a way, without reading the image as a <code>UIImage</code>, to add or copy the saved image to Photos?</p>
  <p>It's difficult to search for the subject to find a solution that does not require <code>UIImageWriteToSavedPhotosAlbum</code>.</p>
  <p>The issue is that the saved image is too large to load as a <code>UIImage</code> so I can't use <code>UIImageWriteToSavedPhotosAlbum</code>.</p>
  <p>Edit: It appears that this can be done with <code>PhotoKit</code>. Can someone point me to an example of creating <code>PHAsset</code> from a saved image file? I'm currently searching.</p>
  <p>Edit 2: Hmm seems like it is only possible to modify an existing <code>PHAsset</code> (eg an item that already exists in Photos). Which I guess would be a dead end if that is the case.</p>
