How to hide the status bar with its content on iOS 10 with Swift 3?

Question

I have read this questions, but not only this ones, without finding a solution to my problem:

• Question 1
• Question 2
• Question 3
• Question 4
• Question 5
• Question 6

What it actually happens to me is that I achieve to hide the content of the status bar, but no the status bar itself:

    override var prefersStatusBarHidden: Bool {

        return true

    }

It keeps appearing on the top of the screen, traslucid, with no content at all.

Answer 1

To hide the status bar programmatically in Swift 3:

UIApplication.shared.keyWindow?.windowLevel = UIWindowLevelStatusBar

To bring it back:

UIApplication.shared.keyWindow?.windowLevel = UIWindowLevelNormal 

If you want you can learn more about UIWindowLevel in Apple's docs.
