Apple's missing KeyboardLayoutGuide

• No Subclassing / Protocol inheritance / obscure overrides
• No more keyboard notification handling
• UIKit Friendly
• Takes safeArea into account
• Only animates if view is fully on screen

Simply constrain your views to the KeyboardLayoutGuide's top anchor the way you would do natively:

override func viewDidLoad() {
    super.viewDidLoad()

    // Pin your button to the keyboard
    button.bottomAnchor.constraint(equalTo: view.keyboardLayoutGuide.topAnchor).isActive = true
}

Bonus: if you're using Stevia, this gets even more concise \o/

button.Bottom == view.keyboardLayoutGuide.Top

If you add your view in Interface Builder, don't forget to enable the "Remove at build time" checkbox for the bottom constraint:

By default, KeyboardLayoutGuide will align your item with the bottom safe area. This is a behaviour that can be opt out with the usesSafeArea property.

// Opt out of safe area if needed.
view.keyboardLayoutGuide.usesSafeArea = false
