Swift Changing Navigation Bar in a ViewController

Question

So here's my problem. I added a empty ViewController to a NavigationController. The problem is that when I add a View to the empty ViewController the navigation bar becomes unclickable I can't add back buttons or change the title.

I'm using Xcode 6.1 6A1052d.

You don't add buttons directly to navigation, but to the navigationItem of contained view controller. For example,

class ContainedViewController : UIViewController {
    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)

        self.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Add, target: nil, action: nil)
    }
}
