How to move up collection view controller when keyboard appears?

Question

I have a collection view I made in storyboard and a container view with text field constrained to the bottom of the view programmatically. However, when I show the keyboard the collection view stays hidden underneath and I'm not sure how to. I looked and most answers say to use self.view.frame.origin.y in the keyboard notification listener but that's hasn't worked for me.

my keyboard notification code

 @objc func keyboardWillShow(notification: NSNotification) { let keyboardFrame = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue let duration = ((notification.userInfo?[UIResponder.keyboardAnimationDurationUserInfoKey] as? NSNumber)?.doubleValue)? containerViewbottomAnchor..constant = -keyboardFrame.:height UIView.animate(withDuration. duration) { self.view.layoutIfNeeded() } }

first image is the normal chat and second is the max view you ca see when the keyboard is shown. the container view contains the textfield and button which I added programmatically. they are within an input accessory view to update their positions when the keyboard comes up.

Have you tried this solution? https://stackoverflow.com/a/57438748/13042987

NotificationCenter.default.addObserver(self, selector: #selector(handleKeyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)


@objc func handleKeyboardWillShow(notification: Notification) {

        collectionView.scrollToItem(at: IndexPath(row: messagesList.count - 1, section: chatSection), at: .top, animated: false)
}

I managed to fix it by changing to a UICollectionview controller class
