If you are using storyboard for the viewcontrollers then you have to write like this in your tabbarcontroller class.

class CustomTabbarController : UITabBarController {

    override func viewDidLoad() {

        super.viewDidLoad()

        let storyboard = UIStoryboard(name: "Main", bundle: nil)

        let firstViewController = FirstViewController()
        let navigationController = UINavigationController(rootViewController: firstViewController)
        navigationController.title = "First"
        navigationController.tabBarItem.image = UIImage.init(named: "map-icon-1")

       viewControllers = [navigationController]

        if let secondViewController = storyboard.instantiateViewController(withIdentifier: "SecondViewController") as? SecondViewController {

            let navgitaionController1 = UINavigationController(rootViewController: secondViewController)
            navgitaionController1.title = "Second"
            navgitaionController1.tabBarItem.image = UIImage.init(named: "second-icon-1")
            var array = self.viewControllers
            array?.append(navgitaionController1)
            self.viewControllers = array

        }

    }
}
