If you need to do this in Swift, you can create an extension for the UINavigationBar to allow you to get or set these settings.

extension UINavigationBar {
var titleColor: UIColor? {
    get {
        if let attributes = self.titleTextAttributes {
            return attributes[NSForegroundColorAttributeName] as? UIColor
        }
        return nil
    }
    set {
        if let value = newValue {
            self.titleTextAttributes = [NSForegroundColorAttributeName: value]
        }
    }
}

var titleFont: UIFont? {
    get {
        if let attributes = self.titleTextAttributes {
            return attributes[NSFontAttributeName] as? UIFont
        }
        return nil
    }
    set {
        if let value = newValue {
            self.titleTextAttributes = [NSFontAttributeName: value]
        }
    }
    }
}

You can then set the color and font like this:

navigationBar.titleColor = UIColor.redColor()
navigationBar.titleFont = UIFont.systemFontOfSize(12)
