Cannot change color of navigation bar title text

override func viewDidLoad() 
{
    super.viewDidLoad()
    self.navigationController?.navigationBar.barTintColor = UIColor(red: 0, green: 0, blue: 0, alpha: 1.0)
    let attr: NSMutableDictionary! = [NSForegroundColorAttributeName: UIColor.whiteColor()]
    UINavigationBar.appearance().titleTextAttributes = attr
    self.view.backgroundColor = UIColor.whiteColor()
}

It is said that 

'Cannot assign value of type 'NSMutableDictionary!' to type '[String : AnyObject]?''

on this line 

UINavigationBar.appearance().titleTextAttributes = attire

and if I change it to 

UINavigationBar.appearance().titleTextAttributes = attr as! [String: AnyObject]

Although it has no error, but it can change the text's color. Why?

You can change color of title text navigation bar, for app in general. Just add this at your AppDelegate.swift in didFinishLaunchingWithOptions function. 

UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor.whiteColor()]

Try this: 

self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.redColor()]
