Code tested in Swift 3.

Note: When, I, try your code. I was facing the same issue. Somehow, I managed to get around...

class SearchVC: UITableViewController,UISearchBarDelegate,UISearchResultUpdating {

var resultSearchController = UISearchController()

override func viewDidLoad() {
    super.viewDidLoad()

     configureSearchController()
 }


override var prefersStatusBarHidden: Bool {

    return true
}


func configureSearchController() {

    self.resultSearchController = ({
        let controller = UISearchController(searchResultsController: nil)
        controller.searchResultsUpdater = self
        controller.dimsBackgroundDuringPresentation = false
        controller.hidesNavigationBarDuringPresentation = false
        controller.searchBar.searchBarStyle = .default
        controller.searchBar.sizeToFit()
        controller.searchBar.setShowsCancelButton(false, animated: true)
        controller.searchBar.keyboardAppearance = .default

        self.tableView.tableHeaderView = controller.searchBar

        //controller.searchBar.tintColor = UIColor(patternImage: UIImage(named: "xxxx")!)
        // controller.searchBar.setBackgroundImage(UIImage(named: "xxxx"), forBarPosition: UIBarPosition.Top, barMetrics: UIBarMetrics.Default)
        //  controller.searchBar.backgroundImage = UIImage(named: "xxxx")
        // controller.searchBar.setImage(UIImage(named: "search-icon.png"), forSearchBarIcon: UISearchBarIcon.Search, state: UIControlState.Normal)

        return controller
    })()


    for subView in self.resultSearchController.searchBar.subviews
    {
        for subsubView in subView.subviews
        {
            if let textField = subsubView as? UITextField
            {
                textField.attributedPlaceholder = NSAttributedString(string: NSLocalizedString("Search Text", comment: ""), attributes: [NSForegroundColorAttributeName: UIColor.red])

                textField.adjustsFontSizeToFitWidth = true
                textField.allowsEditingTextAttributes = true


                textField.textColor = UIColor.red
                textField.layer.borderColor = UIColor.gray.cgColor
                textField.layer.cornerRadius = 5
                textField.layer.masksToBounds = true

                textField.layer.borderWidth = 0.215

            }
         }  
      }
   }
}

Updated:

  func updateSearchResults(for searchController: UISearchController) {}

Output from above code..hope, my answer will fix your problem....

Try to call configureSearchController() in viewDidLoad. And don't forget to call super.viewWillAppear(animated:) in your viewWillAppear.

I've made an open source project SearchTableView

self.searchController.searchBar.sizeToFit()
self.tableHeaderView = self.searchController.searchBar

searchTableView.layoutMargins = UIEdgeInsets.zero
definesPresentationContext = true
extendedLayoutIncludesOpaqueBars = true
