iOS - How to force Portrait mode when currently in Landscape mode

In our app, there is one ViewController should only be available in Portrait mode, hence we've used the usual way of making sure that only this mode works:

-(UIInterfaceOrientationMask)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationPortraitUpsideDown;
}

But if the user is in landscape mode before, and then switches to this specific ViewController, it does not rotate to Portrait mode automatically. Hence, we were looking for a way to force Portrait mode and found this:

[[UIDevice currentDevice] setValue:
 [NSNumber numberWithInteger: UIInterfaceOrientationPortrait]
                            forKey:@"orientation"];

It works fine, but since it's not an official way of doing things, we might get rejected now or in the future.

Is there a way to achieve the same result but with non-private APIs?

EDIT: I am specifically asking how to avoid using the solution posted in this question (How do I programmatically set device orientation in iOS7?), so how can it even possibly be a duplicate?

This help me.

In Your ViewController


override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return .landscapeLeft // or .landscapeRight or As per your requirement 
}

override var shouldAutorotate: Bool {
    return true
}

In DidLoad method



let appDelegate = UIApplication.shared.delegate as! AppDelegate
        appDelegate.myOrientation = .landscape // or .landscapeRight or As per your requirement

In App Delegates

 var myOrientation: UIInterfaceOrientationMask = .portrait

  func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
            return myOrientation
        }

shouldautorotate method should return NO for that view controller. If this doesn't work then use post notifications to manage orientation.
