Attempting to Change the UIStatusBar Tint Color

Question

I am trying to change the UIStatusBar tint color in a specific UIViewController.

Here is my code:

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)

    self.setNeedsStatusBarAppearanceUpdate()

}

Nothing is happening.

On a UINavigationController, preferredStatusBarStyle is not called because its topViewController is preferred to self. So, to get preferredStatusBarStyle called on an UINavigationController, you need to change its childViewControllerForStatusBarStyle.

To do it for one UINavigationController:

class MyRootNavigationController: UINavigationController {
    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
    override var childViewControllerForStatusBarStyle: UIViewController? {
        return nil
    }
}
