}

override func viewDidLoad() {
    super.viewDidLoad()
    
    let navigationBar = UINavigationBar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 100))
}

override func viewDidLoad() {
    super.viewDidLoad()
    
    let navigationBar = UINavigationBar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 100))
    
    self.navigationController?.navigationBar = navigationBar
}

override func viewDidLoad() {
    super.viewDidLoad()
    
    let navigationBar = UINavigationBar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 100))
    
    self.navigationController?.navigationBar = navigationBar
    
    self.navigationController?.view.layoutIfNeeded()
}
