To detect if a specific TarBarItem has been selected I use this on my custom TabBarController:

    class MainTabBarController: UITabBarController, UITabBarControllerDelegate {

        override func viewDidLoad() {
            super.viewDidLoad()

            self.delegate = self

        }


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

        let selectedIndex = tabBarController.viewControllers?.firstIndex(of: viewController)!
        if selectedIndex == 0 {
            print("first tab bar was selected") 
        } else {
            //do whatever
        }
    }

}
