Swift 3.0 - how to hide status bar after calling UIImagePickerController?

Question

Happy New Year!

I want to hide status bar after calling UIImagePickerController on iOS 10.2. You know there are already several questions about it with some answers,

Answer 1

The status bar can be permanently hidden with the following extension to UIImagePickerController :

extension UIImagePickerController {
    open override var childViewControllerForStatusBarHidden: UIViewController? {
        return nil
    }

    open override var prefersStatusBarHidden: Bool {
        return true
    }
}

This is working for Swift 3, on iOS 10.
