Perfect white background on searchBar

func setupSearchbarController(){
    if #available(iOS 11.0, *) {
        let sc = UISearchController(searchResultsController: nil)
        sc.delegate = self
        let scb = sc.searchBar
        scb.tintColor = UIColor.white
        scb.barTintColor = UIColor.white

        if let textfield = scb.value(forKey: "searchField") as? UITextField {
            textfield.textColor = UIColor.white
            textfield.backgroundColor = UIColor.white
            if let backgroundview = textfield.subviews.first {

                // Background color
                backgroundview.backgroundColor = UIColor.white

                // Rounded corner
                backgroundview.layer.cornerRadius = 10;
                backgroundview.clipsToBounds = true;
            }
        }

        if let navigationbar = self.navigationController?.navigationBar {
            navigationbar.barTintColor = AppColor.themeColor
        }
        navigationItem.searchController = sc
        navigationItem.hidesSearchBarWhenScrolling = false
    }
