For iOS 13 and later

    guard let navigationBar = navigationController?.navigationBar else { return }
    navigationBar.isTranslucent = true
    if #available(iOS 13.0, *) {
        let appearance = UINavigationBarAppearance()
        appearance.configureWithTransparentBackground()
        appearance.backgroundImage = UIImage()
        appearance.backgroundColor = .clear
        navigationBar.standardAppearance = appearance
    } else {
        navigationBar.setBackgroundImage(UIImage(), for: .default)
        navigationBar.shadowImage = UIImage()
    }
