Make Search Bar Become First Responder

I have a UISearchController inside of a UINavigationBar. The user has to tap on a UIBarButtonItem, in which I instantiate a new UIViewController then present it, in order to begin searching.

class ViewController: UIViewController {

  var searchController: UISearchController! 

  override func viewDidLoad() {
    super.viewDidLoad()
    setupSearchController()
  }

  func setupSearchController() {
    searchController = UISearchController(searchResultsController: nil)
    searchController.searchBar.delegate = self
    searchController.searchResultsUpdater = self
    searchController.searchBar.showsCancelButton = true
    searchController.dimsBackgroundDuringPresentation = false
    searchController.hidesNavigationBarDuringPresentation = false

    definesPresentationContext = true
    navigationItem.titleView = searchController.searchBar
  }

}

I've done plenty of research before hand, but still can't manage to find a solution...

Help in making the search controller become the first responder would be very much appreciated.

Making the UISearchBar the first responder on the main thread was the solution. 

override func viewDidAppear(_ animated: Bool) {
  super.viewDidAppear(animated)

  DispatchQueue.main.async {
    self.searchController.searchBar.becomeFirstResponder()
  }
}
