Answer 1

This gets the length (in points) of the portion of a view controller's view that is overlaid by translucent or transparent UIKit bars.

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    let topSpace:CGFloat
    let bottomSpace:CGFloat
    if #available(iOS 11.0, *) {
        topSpace = self.view.safeAreaInsets.top
        bottomSpace = self.view.safeAreaInsets.bottom
    } else {
        topSpace = self.topLayoutGuide.length
        bottomSpace = self.bottomLayoutGuide.length
    }
}
