Easy solution in Swift3 - we need to make CustomSearchBar without cancel button and then override the corresponding property in new CustomSearchController:

class CustomSearchBar: UISearchBar {

override func setShowsCancelButton(_ showsCancelButton: Bool, animated: Bool) {
    super.setShowsCancelButton(false, animated: false)
}}


class CustomSearchController: UISearchController {

lazy var _searchBar: CustomSearchBar = {
    [unowned self] in
    let customSearchBar = CustomSearchBar(frame: CGRect.zero)
    return customSearchBar
    }()

override var searchBar: UISearchBar {
    get {
        return _searchBar
    }
}}

In MyViewController I initialize and configure searchController using this new custom subclass:

    var mySearchController: UISearchController = ({
    // Display search results in a separate view controller
    //        let storyBoard = UIStoryboard(name: "Main", bundle: Bundle.main)
    //        let alternateController = storyBoard.instantiateViewController(withIdentifier: "aTV") as! AlternateTableViewController
    //        let controller = UISearchController(searchResultsController: alternateController)
    let controller = CustomSearchController(searchResultsController: nil)
    controller.searchBar.placeholder = NSLocalizedString("Enter keyword (e.g. iceland)", comment: "")
    controller.hidesNavigationBarDuringPresentation = false
    controller.dimsBackgroundDuringPresentation = false
    controller.searchBar.searchBarStyle = .minimal
    controller.searchBar.sizeToFit()
    return controller
})()
