Here is how you can proceed,

class VCA: UIViewController {
    @IBAction func onTapNextButton(_ sender: UIButton) {
        if let controller = self.storyboard?.instantiateViewController(withIdentifier: "VCB") as? VCB {
            self.present(controller, animated: true, completion: nil)
        }
    }
}

Since VCC is embedded in a UINavigationController , you need to present UINavigationController instead of VCC .

For this subclass UINavigationController and set it as class of UINavigationController in the storyboard .

class VCB: UIViewController {
    @IBAction func onTapNextButton(_ sender: UIButton) {
        if let controller = self.storyboard?.instantiateViewController(withIdentifier: "NavVC") {
            self.dismiss(animated: false, completion: nil)
            self.presentingViewController?.present(controller, animated: true, completion: nil)
        }
    }
}

class NavVC: UINavigationController {}

class VCC: UIViewController {
    @IBAction func onTapCloseButton(_ sender: UIButton) {
        self.navigationController?.dismiss(animated: true, completion: nil)
    }
}
