You haven't provided a lot of information, so it's a bit hard to tell what you are asking.

You need to use push transitions from the navigation controller's root view controller to each subsequent view controller. If you do that you should have back buttons on all but the root view controller.

The call is 

pushViewController(_:animated)

And the function definition is 

func pushViewController(viewController: UIViewController,
           animated animated: Bool)

You can also use push segues, which invoke the push call above.
