Мне нужно сделать кастом UISearchBar, используя UITextField.
Я пытаюсь сделать это сам, но ничего не получается. Пожалуйста, напишите код для UITextField, который будет работать как UISearchBar
Это код, где я использую UISearchBar, но мне нужно изменить на UITextField
class FoodViewController: UIViewController {
override var preferredStatusBarStyle: UIStatusBarStyle { return .lightContent }

var foods = [FoodModel]()
var searchedFoods = [FoodModel]()
var searching = false

searchBar.barStyle = .black
searchBar.delegate = self
self.view.addSubview(searchBar)
}
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
self.updateLayout(with: self.view.frame.size)

self.tableView.frame = CGRect.init(x: 0, y: 45, width: size.width, height: 400)

Database.database().reference().child("food").observe(.childAdded) { (snapshot) in
