Hi Brian, Why Don't you use transition delegate here? What is the benefit of your way?

hi Brian when you hide the Today's navigationBar the title disappears how to have the title appeared like the appStore

Hey Brian, Absolutely brilliant tutorial so far! I dont think that its just me: Animations are much more easier than we all think they are! And this is thanks to your guidance! Just a question: Since we are going to require the "startingFrame" when removing the redView, why not pass it as a parameter in the handleRemoveRedView() method? What is the benefit of declaring it as a local variable? Thank you so much!

This topic is #1 reason I purchased this course

i added the gesture recognizer to my view but it isnt being called i even checked by adding a print statement in the function. can anyone help , i even tried adding the delegate and all that but still not being called ``` func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { let fullScreen = UIView() fullScreen.isUserInteractionEnabled = true fullScreen.backgroundColor = .red let tapGesture = UIGestureRecognizer(target: self, action: #selector(handleTap(gesture:))) tapGesture.delegate = self fullScreen.addGestureRecognizer(tapGesture) view.addSubview(fullScreen) guard let cell = collectionView.cellForItem(at: indexPath) else {return} guard let startingFrame = cell.superview?.convert(cell.frame, to: nil) else{return} fullScreen.frame = startingFrame UIView.animate(withDuration: 0.7, delay: 0, usingSpringWithDamping: 0.7, initialSpringVelocity: 0.7, options: .curveEaseOut, animations: { fullScreen.frame = self.view.frame }) { (done) in } } @objc func handleTap(gesture: UITapGestureRecognizer){ print("tapped") gesture.view?.removeFromSuperview() } ```

Came for this specific feature, got so much more.. fantastic project

Hey Brian, We add the redView when we click on the cell What is the difference between collectionView.addSubview(redView) vs view.addSubview(redView) ? I still don't understand when to use view vs collectionView when in a UICollectionViewController could you explain, thank you!
