Swift 4:

Created an extension for UIViewController that can pop UIViewControllers in NavigationController stack depending in supplied number of times

extension UIViewController {

    func pop(numberOfTimes: Int) {
        guard let navigationController = navigationController else {
            return
        }
        let viewControllers = navigationController.viewControllers
        let index = numberOfTimes + 1
        if viewControllers.count >= index {
            navigationController.popToViewController(viewControllers[viewControllers.count - index], animated: true)
        }
    }
}
