I think you cannot push Navigation Controller inside another uinavigation controller but alternativaly you can present another nav controller. Hope it works for you. I have created simple demo like this.

class ViewController: UIViewController {
    @IBOutlet weak var btnCustom: UIButton!
    override func viewDidLoad() {
        super.viewDidLoad()
    // Do any additional setup after loading the view.
    }
    @IBAction func btnForward(_ sender: Any) {
        /*Uncomment the code if you want to present programatically*/
        /*if let navi2 = self.storyboard?.instantiateViewController(withIdentifier: "nav2"){
            self.present(navi2, animated: true) {
            }
        }*/
    }

}

class ViewController2: UIViewController {
    @IBOutlet weak var btnCustom: UIButton!
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    @IBAction func btnBack(_ sender: Any) {
        if let parentNav = self.navigationController {
            parentNav.dismiss(animated: true) {

            }
        }
    }}
