I have in Obj-C

@interface NoneBarsViewController : UIViewController

and in Swift

final class SettingsViewController: NoneBarsViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
}

there is a warning for viewDidLoad:

Method does not override any method from its superclass

Bridging-Header.h

#import "NoneBarsViewController.h"

Is there a way to see in Swift that NoneBarsViewController is a UIViewController?
