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

var searchController = UISearchController(searchResultsController: nil)
searchController.searchBar.setDefaultSearchBar()
searchController.searchResultsUpdater = self

if #available(iOS 11.0, *) {
    navigationItem.searchController = searchController
} else {
    tableView.tableHeaderView = searchController.searchBar
}

extension UISearchBar {
    func setDefaultSearchBar() {
        self.tintColor = UIColor.blue
        self.searchBarStyle = .minimal
        self.backgroundImage = UIImage(color: UIColor.clear)
        let searchBarTextField = self.value(forKey: "searchField") as! UITextField
        searchBarTextField.textColor = UIColor.white
        searchBarTextField.tintColor = UIColor.blue
        searchBarTextField = .dark
    }
}

However, the appearance of the search bar fails to update when running the same code on iOS 11.

iOS 10:

iOS 11:

Much of the attention to this question so far has focused on the text color of the search bar. I am looking at more than this - the background color, tint color, the search indicator, clear button color, etc.

Try setting the search bar's bar style.

searchController.searchBar.barStyle = UIBarStyleBlack;
