When you are sure you've already set a UIBarButtonItem you can do:

self.navigationItem.leftBarButtonItem!.title = "myTitle"

To change e.g. the color you can do the following:

self.navigationItem.leftBarButtonItem!.tintColor = UIColor.redColor()

When you haven't set it in your storyboard you can do:

self.navigationItem.leftBarButtonItem = UIBarButtonItem()

For changing the font, do the following:

self.navigationItem.leftBarButtonItem!.setTitleTextAttributes([NSFontAttributeName: UIFont(name: "FONTNAME", size: 20)!], forState: .Normal)

Maybe I should mention that you mustn't use self.navigationController because when setting the navigationController's buttons they aren't displayed on the screen so as a result the buttons which are on the screen and had been set in the storyboard have to be self.navigationItem...
