Try this code,

UITextField *txfSearchField = [_searchBar valueForKey:@"_searchField"];
txfSearchField.backgroundColor = [UIColor redColor];

Answer 2

This is the code I used to make the search bar white:

if let textfield = searchController.searchBar.value(forKey: "searchField") as? UITextField {
            if let backgroundview = textfield.subviews.first {
                backgroundview.backgroundColor = UIColor.init(white: 1, alpha: 1)
                backgroundview.layer.cornerRadius = 10
                backgroundview.clipsToBounds = true
            }
        }

This should work for you

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

            if let navigationbar = self.navigationController?.navigationBar {
                //navigationbar.tintColor = UIColor.green
                //navigationbar.backgroundColor = UIColor.yellow
                navigationbar.barTintColor = UIColor.blue
            }

            navigationController?.navigationBar.tintColor = UIColor.green
            navigationItem.searchController = sc
            navigationItem.hidesSearchBarWhenScrolling = false
        }
}

Objective C

if (@available(iOS 11.0, *)) {
    self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
    self.searchController.searchResultsUpdater = self;
    self.searchController.searchBar.delegate = self;
    self.searchController.dimsBackgroundDuringPresentation = NO;
    self.navigationItem.searchController=self.searchController;
    self.navigationItem.hidesSearchBarWhenScrolling=NO;
    self.searchController.searchBar.searchBarStyle = UISearchBarStyleProminent;
    self.searchController.searchBar.showsBookmarkButton = NO;
    self.searchController.searchBar.placeholder = @"Search";
    self.searchController.searchBar.tintColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:1];
    self.searchController.searchBar.barTintColor=[UIColor colorWithRed:1 green:1 blue:1 alpha:1];
    UITextField *txfSearchField = [self.searchController.searchBar valueForKey:@"_searchField"];
    txfSearchField.tintColor=[UIColor colorWithRed:21/255.0 green:157/255.0 blue:130/255.0 alpha:1];
    txfSearchField.textColor=[UIColor colorWithRed:1 green:1 blue:1 alpha:1];
    txfSearchField.backgroundColor=[UIColor whiteColor];
    UIView *backgroundview= [[txfSearchField subviews]firstObject ];
    backgroundview.backgroundColor=[UIColor whiteColor];
    // Rounded corner

Tested on ios 13

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
    }
}

Answer 6

I changed the background of the text field with this code inside AppDelegate.

Swift 4

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        
        //background color of text field
         UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).backgroundColor = .cyan
        
        }

This is the result
