Fade title label with background

[MaxHasADHD]

I'd like to fade the title label along with the background. I found one way of doing it for iOS 13+. I tried simply finding the label view and setting the alpha but as soon as the title updates the label is fully visible again.

if #available(iOS 13.0, *) {
            if let color = navigationBar.scrollEdgeAppearance?.titleTextAttributes [NSAttributedString.Key.foregroundColor] as? UIColor {
                navigationBar.scrollEdgeAppearance?.titleTextAttributes [NSAttributedString.Key.foregroundColor] = color.withAlphaComponent(alpha)
            }
            
            if let color = navigationBar.standardAppearance.titleTextAttributes [NSAttributedString.Key.foregroundColor] as? UIColor {
                navigationBar.standardAppearance.titleTextAttributes [NSAttributedString.Key.foregroundColor] = color.withAlphaComponent(alpha)
            }
            
            if let color = navigationBar.compactAppearance?.titleTextAttributes [NSAttributedString.Key.foregroundColor] as? UIColor {
                navigationBar.compactAppearance?.titleTextAttributes [NSAttributedString.Key.foregroundColor] = color.withAlphaComponent(alpha)
            }
        }
