What is the 'bug' you are seeing exactly? – Rosemari

"Bug" will be if i try do similar with native methods. This is right way, but i don`t know how did it – Mercie

So that is showing the correct way and looks ok? You are doing it using 'native' methods and it's not working? Well start by showing what you are getting and then code you are using. – Rosemari

edited post with link on animation bug – Mercie

So is this a new question then or are you looking for an answer to that one? – Rosemari

I am looking how to do like on gif. Like Apple realize in their apps. All ways that I finded are workarounds and don't look like in Files app – Mercie

Ok cool. Post the code/setup you have tried so far. – Rosemari

Answer 1

you can add some line of code in ViewController -viewDidLoad some line of code for search bar in navigation bar

self.navigationController?.navigationBar.prefersLargeTitles = true
self.navigationItem.largeTitleDisplayMode = .automatic
let search = UISearchController(searchResultsController: nil) // Declare the searchController
self.navigationItem.searchController = search
