UISearchController iOS 11 Customization

Question

I had been using the following code prior to iOS 11 to customize the appearance of the UISearchController search bar:

var searchController = UISearc         


        

Answer 1

To properly set the text typed into the search bar to white use (when using a dark field color):

searchController.searchBar.barStyle = .black

To set the textfield background color

if #available(iOS 11.0, *) {

        if let textfield = searchController.searchBar.value(forKey: "searchField") as? UITextField {
            if let backgroundview = textfield.subviews.first {

                // Background color
                backgroundview.backgroundColor = UIColor.white

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

However using something like

textfield.textColor = UIColor.blue

in the above does not seem to work.
