First add extension in view controller

extension UIView {
    var parentViewController: UIViewController? {
        var parentResponder: UIResponder? = self
        while parentResponder != nil {
            parentResponder = parentResponder!.next
            if let viewController = parentResponder as? UIViewController {
                return viewController
            }
        }
        return nil
    }
}

Now Use it Like this

let vc = self.parentViewController

or

if let parentVC = self.parentViewController {
    if let parentVC = parentVC as? someViewController {
        // parentVC is someViewController
    } else if let parentVC = parentVC as? anotherViewController {
        // parentVC is anotherViewController
    }
}
