I can change bottom UI bar with:
UIBarButtonItem.appearance().tintColor = UIColor.redColor()
Can't locate how to do same with top-right "Done" button.
Here's where that works in AppDelegate.swift:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    UIBarButtonItem.appearance().tintColor = UIColor.redColor()
    return true
}
Adding this does not work:
UINavigationBar.appearance().tintColor = UIColor.redColor()
