In a UIKit chat screen, the input bar has to sit right on top of the keyboard and follow it as it rises. How would you connect keyboard height changes to Auto Layout constraints?
From iOS 15, constrain the input bar's bottom to view.keyboardLayoutGuide.topAnchor, and the system updates the constraint and matches the animation when the keyboard appears, disappears, or changes height, so no notification code is needed.
