At the end of the video, you added to PopAnimator, inside UIView.animate:

if !self.presenting {
    let viewController = transitionContext.viewController(forKey: .to) as! ViewController
    viewController.selectedImage!.isHidden = false
}

However, when practicing before your video, I simply added a single line to the ViewController and this had the same result

func animationController(
    forDismissed dismissed: UIViewController
    ) -> UIViewControllerAnimatedTransitioning? {
    transition.presenting = false
   ->  selectedImage?.isHidden = false
    return transition
}

Any reason, longer term mine idea might hit issues or conflicts?
