KeyboardAdjustable takes into account the two most common ways we adjust our view when the keyboard appears:

• When you have a ScrollView and you want to change its contentInset when the keyboard appears
• When you have a bottom constraint for a UIView and you want to change it’s value when the keyboard appears

With only one line of code you'll be able to handle these scenarios without having to implement the observers in your own UIViewController.

1. Import KeyboardAdjustable on your UIViewController file
2. Add the KeyboardAdjustable protocol to your UIViewController
3. Setup a KeyboardAdjustingStrategy on your viewDidLoad

Note: Make sure you're calling registerForKeyboardNotifications() on your viewDidLoad and unregisterForKeyboardNotification() on your viewDidDisappear.

class SingleConstraintViewController: UIViewController, KeyboardAdjustable {

    var keyboardAdjustingStrategy: KeyboardAdjustingStrategy?

    @IBOutlet weak var bottomConstraint: NSLayoutConstraint!
    
    override func viewDidLoad() {
        super.viewDidLoad()

        // Register for keyboard notifications
        registerForKeyboardNotifications()
        
        // Set your desired strategy to adjust the view when the keyboard appears
        self.keyboardAdjustingStrategy = .singleConstraint(
                                          constraint: bottomConstraint, 
                                          originalConstant: bottomConstraint.constant,
                                          spaceAboveKeyboard: 20)
    }

    override func viewDidDisappear(_ animated: Bool) {
        super.viewDidDisappear(animated)
        // Unregister for keyboard notifications
        unregisterForKeyboardNotification()
    }
}
