I have added an extension like this:

extension UINavigationController { 
    @IBInspectable var hideLeftItem: Bool {
        get { return self.hideLeftItem }
        set {
              self.navigationItem.leftBarButtonItem = nil
            }
        }
}

But it doesn't work when I set it in the identity inspector. I have tried to set it in the identity inspector both in the navigation controller and the navigation bar as well as the navigation item itself (but then extending the item instead). If I just set the code straight in viewDidLoad it works, but I don't want that. What am I missing?

@VitaliiShvetsov, that answer was 5 years ago, it is supposed to work with extensions these days. – holex Aug 25 '20 at 09:09
Where am I supposed to set it? In the navigation controller? – Joakim Sjöstedt Aug 25 '20 at 09:34
Is your goal to hide the "Back" button, without needing to add code in each view controller? – DonMag Aug 25 '20 at 12:40
