Status bar color: preferredStatusBarStyle doesn't work

Question

Solution I found in stackoverflow - it is override preferredStatusBarStyle in view controller but it does not work for me and I cant understand why. Status bar still black.

My prerequisites:

class ViewController: UIViewController {

@IBOutlet weak var containerView: ContainerView!
@IBOutlet weak var collectionView: UICollectionView!

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

override func viewDidLoad() {
    super.viewDidLoad()
}
}

First Make Sure These Settings

1. Project->Target->Deployment Info

2. In info.plist
