'How to record video only in portrait in iOS but not in landscape?

I want to allow user to record a video only in portrait mode(orientation) and restrict the user to record in landscape. I'm using UIImagePickerController and I couldn't find any orientation options in it. could anyone help me out in this?

Write below code in AppDelegate:

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

    guard let mainController = navigationController else { return UIInterfaceOrientationMask.all }
    if ((mainController.visibleViewController as? CameraVC) != nil) == false {
        //This VC should support only Portrait Mode.
        return UIInterfaceOrientationMask.portrait
    } else {
        //Else support All Modes.
        return UIInterfaceOrientationMask.all
    }
}

And It will Restrict Your "CameraVC" to Rotate in landscape Mode.
