Implement the UITabBarControllerDelegate tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) method like this:
func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool { if let navigationController = viewController as? UINavigationController{ navigationController.popToRootViewController(animated: false) } return true }
