Hiding Cancel button on search bar in UISearchController

Rejoice! As of iOS 13, there is access to automaticallyShowsCancelButton on UISearchController. Set it to false to hide the cancel button.

I ended up subclassing both UISearchBar and UISearchController as suggested:

CustomSearchBar.swift

import UIKit

class CustomSearchBar: UISearchBar {

    override func layoutSubviews() {
        super.layoutSubviews()
        setShowsCancelButton(false, animated: false)
    }
}

CustomSearchController.swift

import UIKit

class CustomSearchController: UISearchController, UISearchBarDelegate {

    lazy var _searchBar: CustomSearchBar = {
        [unowned self] in
        let result = CustomSearchBar(frame: CGRectZero)
        result.delegate = self

        return result
    }()

    override var searchBar: UISearchBar {
        get {
            return _searchBar
        }
    }
}

func didPresentSearchController(_ searchController: UISearchController) {
    searchController.searchBar.becomeFirstResponder()
    searchController.searchBar.showsCancelButton = true
}


func didDismissSearchController(_ searchController: UISearchController) {
    searchController.searchBar.showsCancelButton = false
}

In my case all the above solutions dint work. You need to show in didPresentSearchController and hide it in didDismissSearchController. Earlier I was just hiding in didDismissSearchController which was still showing Cancel button on cancelling.
