ios – Utilizing UIBarButtonItemAppearance have each the system and the customized again button photographs

        look.titleTextAttributes = [.foregroundColor: textColor]
        look.largeTitleTextAttributes = [.foregroundColor: textColor]
        look.configureWithOpaqueBackground()
        look.backgroundColor = coloration
        
        let again = UIBarButtonItemAppearance()
        again.regular.backgroundImage = UIImage(named: "white_back_arrow")

How can I keep away from this behaviour?
