swift ios cant change navigation bar title

Question

I have a modal VC and I have dragged in a navigation bar using storyboard:

But now I can only change the title in storyboard and not in code. I need to be able to change it in code since the title will be dynamic.

I have tried both of these:

self.title = "some title"

navigationBar.topItem.title = "some title"

But none of them work and I dont get any warning/error either

@HaydenHolligan I want the title to display the category picked in the previously VC — user2636197, Aug 10 '16 at 20:03

If your NavigationBar is connected to your ViewController per Outlet, this works fine:

class ViewController: UIViewController {

    @IBOutlet weak var navigationbar: UINavigationBar!

    override func viewDidLoad() {
        super.viewDidLoad()

        navigationbar.topItem!.title = "Dynamic"
    }

}

I can use just navigationItem.title="test" without any Outlets – djdance Nov 08 '17 at 13:45
