Answer 1

In your UIViewController:

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    UIApplication.shared.isStatusBarHidden = true
}

 override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    //It will show the status bar again after dismiss
    UIApplication.shared.isStatusBarHidden = false
}

override var prefersStatusBarHidden: Bool {
    return true
}
