if let iuRightNavigationButton = self.navigationItem.rightBarButtonItem
{
iuRightNavigationButton.enable = false
}

It basically checks for the rightBarbutton item,if there is one then it disables.You need not declare any iboutlet to do this

There are two ways of do it:

  1. As you have created the button using Interface Builder, then you can declare an @IBOutlet for it using the drag-and/drop utility of Xcode and disable/hide the button in the navigation bar in the following way:

    // hide the button
self.rightButton.hidden = true

// disable the button
self.rightButton.enabled = false

// change its title
self.rightButton.setTitle("NEW TITLE", forState: .Normal)

    Where the @IBOutlet is like this:

    @IBOutlet weak var rightButton: UIButton!

  2. In case you don't want to declare any @IBOutlet you can set the self.navigationItem.rightBarButtonItem to nil in any place you want int this way:

    // remove the button
self.navigationItem.rightBarButtonItem = nil

// disable the button
self.navigationItem.rightBarButtonItem?.enabled = false

    And the above code disable any previous button you have set.

I hope this help you.

try to create outlet in your view controller: @IBOutlet weak var doneButton : UIBarButtonItem! link the barbuttonItem to your doneButton variable in the storyboard.

assigned the value false when to disable it. At view did load:

doneButton.enabled = false
