Answer 1

You need to check if your view controller is included in a container (i.e. UINavigationController). If that is the case, the full procedure is this:

1) Set the View controller-based status bar appearance value in info.plist file to YES

2) In your child controller add this code:

override var prefersStatusBarHidden: Bool{
        return true
   }

3) Add this extension:

// gives control of the status bar appearance to the top controller
extension UINavigationController {
    override open var childViewControllerForStatusBarHidden: UIViewController? {
        return self.topViewController
    }
}

You already have point 1 and 2. Same logic applies to UITabBarController
