title: image shared to Snapchat using UIActivityViewController gets zoomed and cropped
body: <p>I'm having problems with sharing images with UIActivityViewController to snapchat. Shared images are zoomed and cropped (it works fine with other apps: facebook, messenger, notes, twitter, viber, iCloud...).</p>
  
  <p>Here is my code:</p>
  
  <pre><code>let avc = UIActivityViewController(activityItems: [waterMarkedImage], applicationActivities: nil)
  
  avc.completionWithItemsHandler = { activity, success, items, error in
       self.setTimer()
  }
  self.present(avc, animated: true, completion: self.stopTimer)
  </code></pre>
  
  <p>The result - shared image is cropped: </p>
