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

For those of you who change to landscape mode, you gotta make sure to use viewSafeAreaInsetsDidChange after the rotation to get the most updated values:

private var safeAreaInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)

override func viewSafeAreaInsetsDidChange() {
        if #available(iOS 11.0, *) {
            safeAreaInsets = UIApplication.shared.keyWindow!.safeAreaInsets
        }
}
