Setting title in view controller make title on tabbar appear

[molchanovskiy]

When I switch go from first tabbar controller to second title appears at the bottom.

override func viewDidLoad() {
    super.viewDidLoad()

    self.title = "Timers"

    self.navigationItem.leftBarButtonItem = UIBarButtonItem.init(image: UIImage.init(named: "close"), style: UIBarButtonItemStyle.plain, target: self, action: #selector(closeDidTap))
}
