override func viewDidAppear(_ animated: Bool) {
       super.viewDidAppear(animated)
        // create new view
        let newView = UIImageView(image: UIImage(named: "banner"))
        newView.center = animationContainerView.center
        
        // add the enw view via transition
        UIView.transition(with: animationContainerView,
                          duration: 0.33,
                          options: [.curveEaseOut, .transitionFlipFromBottom],
                          animations: {
                            self.animationContainerView.addSubview(newView)
        }, completion: nil)

create a new view named newView in viewDidAppear, ‘newView’ is a local variable, why ‘newView’ is global variable when removing ?

//remove the view via transition

   UIView.transition(with: animationContainerView, duration: 0.33, 
        options: [.curveEaseOut, .transitionFlipFromBottom],  
        animations: {
            self.newView.removeFromSuperview()
    }, completion: nil)

@viho Both code snippets are from the theoretical part of the chapter. They are independent, so the local newView that you add in viewDidAppear(_:) doesn’t have anything to do with the global newView that you remove.

Please let me know if you have any other questions or issues about the whole thing. Thank you!
