＆＃34; HomeTabBarViewController＆＃34;的冗余一致性协议＆＃39; UITabBarControllerDelegate＆＃39; iOS版

Question

首先，我是iOS编程的新手。我无法实施UITabBarControllerDelegate协议。我收到这个错误：

  

＆＃34; HomeTabBarViewController＆＃34;的冗余一致性协议   ＆＃39; UITabBarControllerDelegate＆＃39;

class HomeTabBarViewController: UITabBarController , UITabBarControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.delegate = self
    }

    func tabBarController(_ tabBarController: UITabBarController, didSelect viewController: UIViewController) {
        print("didSelect viewController")
    }

    override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
        print("didSelect item")
    }
}

如何解决此错误？
