How to change the navigation bar title color on Xamarin.iOS

This is how you do that:

UINavigationBar.Appearance.TitleTextAttributes = new UIStringAttributes
{
    ForegroundColor = UIColor.White
};

void StyleNavBar()
    {
        this.NavigationController.NavigationBar.TitleTextAttributes = new UIStringAttributes()
        {
            ForegroundColor = UIColor.White,
            Font = UIFont.FromName("overpass-bold", 14)
        }; 
     }
