On iOS 15 it seems you must use the UINavigationBarAppearance object instead (which in my opinion is far from being an improvement overall)

if #available(iOS 15.0, *) {
    let navigationAppearance = UINavigationBarAppearance()
    navigationAppearance.configureWithDefaultBackground()
    let buttonAppearance = UIBarButtonItemAppearance()
    buttonAppearance.normal.titleTextAttributes = attributes
    buttonAppearance.highlighted.titleTextAttributes = attributes
    navigationAppearance.buttonAppearance = buttonAppearance

    let appearance = UINavigationBar.appearance()
    appearance.standardAppearance = navigationAppearance
    appearance.scrollEdgeAppearance = navigationAppearance
} else {
    let appearance = UIBarButtonItem.appearance()
    appearance.setTitleTextAttributes(attributes, for: .normal)
    appearance.setTitleTextAttributes(attributes, for: .highlighted)
}
