UISearchBar stays on NavigationController after pressing the back button

I have a UISearchBar attached to the UINavigationController and when I tap the back button of the presented UIViewController which contains the UISearchBar it doesn't disappear as I expected, it stays still attached to the nav bar and appears on the parent view controller.

Here's my UISearchBar declaration:

lazy var searchBar: UISearchBar = {
    let sb = UISearchBar()
    sb.placeholder = "Search"

    UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).backgroundColor = UIColor.rgb(red: 230, green: 230, blue: 230) // cor de fundo da search bar
    sb.delegate = self
    return sb
}()

Here's how I attach the UISearchBar to the UINavigationController

navigationController?.navigationBar.addSubview(searchBar)

I tried ti call searchBar.removeFromSuperview() on the viewWillDisappear but it didn't worked.

Any hint?

Thank you

Use self.navigationItem.titleView = searchBar for adding the search bar instead of navigationController?.navigationBar.addSubview(searchBar) and when you need to remove it then replace the titleView by another UIView or make it = nil

to Add

self.navigationItem.titleView = searchBar

to Remove

self.navigationItem.titleView = UIView()
