Barbutton with text
navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Add", style: .plain, target: self, action: #selector(addTapped))
BarButton with your own image
navigationItem.rightBarButtonItem = UIBarButtonItem(image: UIImage(named:"add"), style: .plain, target: self, action: #selector(addTapped))
BarButton with system image
