Hello everyone: Im having some issues with the coloring of the background of my navigation controller. I got it to display the color I canted only when the user is searching through a tableview or a collection but I want to color at the state where you can see the big title of the Nav Bar.

Any ideas? Thank you in advance

I was able to get this to work in my own project (it's target is iOS 13 and above)

 override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        navigationController?.navigationBar.prefersLargeTitles = true

        let appearance = UINavigationBarAppearance()
        appearance.backgroundColor = .purple
        appearance.titleTextAttributes = [.foregroundColor: UIColor.white]
        appearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]

        navigationController?.navigationBar.tintColor = .white
        navigationController?.navigationBar.standardAppearance = appearance
        navigationController?.navigationBar.compactAppearance = appearance
        navigationController?.navigationBar.scrollEdgeAppearance = appearance
}
