Answer 1

You need to set your UISearchControllerDelegate

    class SearchController: UITableViewController, UISearchControllerDelegate, UISearchBarDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        searchController = UISearchController(searchResultsController: nil)
        searchController.delegate = self
        searchController.searchBar.delegate = self

        self.definesPresentationContext = false
    }

in the storyboard also need to change the segue from Show Push, to Show Replace

or use extensions however the cool kids are doing it now.
