Can't hide the top and bottom lines in custom searchBar – Ios swift

I´ve tried to change background color inside class SearchBarView: UIView {}:

searchBar.searchTextField.backgroundColor = .clear
searchBar.backgroundColor = .clear

and tryed something like that inside MainViewController:

searchBar.searchTextField.backgroundColor = .clear
searchBar.backgroundColor = .clear
searchBar.layer.backgroundColor = UIColor.clear.cgColor

but, unfortunately I still see this lines inside my custom searchBar.
How can I get rid of these lines?

My SearchBarView class:

class SearchBarView: UIView {
    lazy var searchBar = createSearchBar()
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        addSubview(searchBar)
        
        searchBar.snp.makeConstraints { make in
            make.leading.equalTo(32)
            make.centerY.equalToSuperview()
            make.height.equalTo(34)
            make.width.equalTo(300)
        }
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

fileprivate extension SearchBarView {
    private func createSearchBar() -> UISearchBar {
        let searchBar = UISearchBar()
        searchBar.placeholder = "   Search"
        searchBar.searchTextField.font = UIFont(name: "MarkPro", size: 15)
        searchBar.searchTextField.backgroundColor = .clear
        let textFieldInsideSearchBar = searchBar.value(forKey: "searchField") as? UITextField
        let imageV = textFieldInsideSearchBar?.leftView as! UIImageView
        imageV.image = imageV.image?.withRenderingMode(UIImage.RenderingMode.alwaysTemplate)
        imageV.tintColor = UIColor(hexString: "FF6E4E")
        return searchBar
    }
}

My MainViewController class:

class MainViewController: UIViewController {
    private var searchBarView: SearchBarView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupSearchBarView()
    }
    private func setupSearchBarView() {
        searchBarView = SearchBarView(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
        view.addSubview(searchBarView)
        
        searchBarView.searchBar.clipsToBounds = true
        searchBarView.searchBar.layer.cornerRadius = 17
        searchBarView.searchBar.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner, .layerMinXMaxYCorner, .layerMaxXMaxYCorner]
        searchBarView.searchBar.searchTextField.clipsToBounds = true
        let directionalMargins = NSDirectionalEdgeInsets(top: 0, leading: 24, bottom: 0, trailing: 0)
        searchBarView.searchBar.directionalLayoutMargins = directionalMargins
        
        searchBarView.snp.makeConstraints { make in
            make.leading.equalToSuperview()
            make.top.equalTo(categoriesView.snp.bottom)
            make.trailing.equalToSuperview()
            make.height.equalTo(60)
        }
    }
}
