   I can't reproduce the problem using the example app. Are there any additional steps I should take?

   Sorry for the late response. I use a table view and I believe that the cell gets removed from stack but the cell was the superview of the image view. So the parent view cannot be found anymore and so the nil appears.

   I'm having the same problem with a collection view, where the imageview is nested within a container whose superview is always nil during this check and fails.

       func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
           let containerView = transitionContext.containerView
           let toView = transitionContext.view(forKey: UITransitionContextViewKey.to)!
           let fromParentView = fromImageView.superview!
   

   The linked PR fixes the probem. Any reason it hasn't been merged? Is the author gone?
