Question

Answer 1

You're making a custom UINavigationBar when one is already provided to you with the UINavigationController.

Try this instead in your ViewController:

override func viewDidLoad() {
    super.viewDidLoad()

    self.title = "Title"

    let navigationBar = navigationController!.navigationBar
    navigationBar.tintColor = UIColor.blueColor()

    let leftButton =  UIBarButtonItem(title: "Left Button", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
    let rightButton = UIBarButtonItem(title: "Right Button", style: UIBarButtonItemStyle.Plain, target: self, action: nil)

    navigationItem.leftBarButtonItem = leftButton
    navigationItem.rightBarButtonItem = rightButton
}
