Keep up with the keyboard

6:21 - Keyboard layout guide

7:56 - usesBottomSafeArea

9:40 - Keyboard dismiss padding

12:11 - Handle willShow or hideKeyboard notifications

func handleWillShowOrHideKeyboardNotification(notification: NSNotification) {
    // Retrieve the UIScreen object from the notification (Added iOS 16.1)
    guard let screen = notification.object as? UIScreen else { return }

    // Determine if the notification’s screen corresponds to your view’s screen
    guard(screen.isEqual(view.window?.screen)) else { return }

    // Get the ending screen position of the keyboard
    guard let keyboardFrameEnd = userInfo[endFrameKey] as? CGRect else { return }

    let fromCoordinateSpace: UICoordinateSpace = screen.coordinateSpace
    let toCoordinateSpace: UICoordinateSpace = view

    // Convert from the screen coordinate space to your local coordinate space
    let convertedKeyboardFrameEnd = fromCoordinateSpace.convert(keyboardFrameEnd, to: toCoordinateSpace)

    // Calculate offset for view adjustment
    var bottomOffset = view.safeAreaInsets.bottom
            
    // Get the intersection between the keyboard's frame and the view's bounds
    let viewIntersection = view.bounds.intersection(convertedKeyboardFrameEnd)
            
    // Check whether the keyboard intersects your view before adjusting your offset.
    if !viewIntersection.isEmpty {
        // Set the offset to the height of the intersection
        bottomOffset = viewIntersection.size.height
    }

    // Use the new offset to adjust your UI
    movingBottomConstraint.constant = bottomOffset
  
    // Adjust view layouts and animate using information in notification
  
    ...

14:38 - Inline predictions

    case `default` = 0
    case no = 1
    case yes = 2
}

let textView = UITextView(frame: frame)
textView.inlinePredictionType = .yes
