Swift/XCode 6.4: add back button to navigation controller in navigation bar

Question

In my app I have this storyboard:

and I would like to add a back button from the second table view back to the first. So I inserted a Navigation controller in order to have a navigation bar in the second table view ad I have created a segue with its identifier from the second table view to the first. But then how can I add a back button? I have tried to drag a button from the library into the navigation controller but it won't let me do it...I had already done this but in this moment I can't remember how. Please can you help me?

Solution 1

In above image you shared you are making your tableview controller as root view controller.You have to kept your navigation controller on root. As you can see in attached image and you don't have to make back button manually as navigation controller has its own default back button.

Solution 2

This example is right how to make storyboard.Try it

self.navigationController?.navigationBar.hidden = false 

In setting of UINavigationController set up like on screenshot
