Get safe area inset top and bottom heights

Question

On the new iPhone X, what would be the most proper way to get both top and bottom height for the unsafe areas?

Answer 1

In iOS 11 there is a method that tells when the safeArea has changed.

override func viewSafeAreaInsetsDidChange() {
    super.viewSafeAreaInsetsDidChange()
    let top = view.safeAreaInsets.top
    let bottom = view.safeAreaInsets.bottom
}
