        someNavigationController.modalPresentationStyle = .custom

        someNavigationController.transitioningDelegate = someNavigationController.topViewController as? MyViewController

        present(someNavigationController, animated: true, completion: nil)

    }

}

extension MyViewController {

    fileprivate var isMaximized: Bool {

        if let controller = navigationController?.presentationController as? PartialModalPresentationController {

            return controller.maximized

        }

        

        return false

    }

    @objc func toggleMaximizeButtonPressed(_ sender: AnyObject) {

        guard let controller = navigationController?.presentationController as? PartialModalPresentationController else {

            return

        }

        

        if isMaximized {

            controller.unmaximizeViewController()

        } else {

            controller.maximizeViewController()

        }

extension MyViewController: UIViewControllerTransitioningDelegate {

    func presentationController(forPresented presented: UIViewController, presenting: UIViewController?, source: UIViewController) -> UIPresentationController? {

        let ctrl = PartialModalPresentationController(presentedViewController: presented, presenting: presenting)

        ctrl.presentationDelegate = self

        ctrl.maximized = true

        return ctrl
