iOS Swift: SearchController with a StoryBoard UISearchBar - ios

Question

Evening, I have built a search controller, and I have also the code to programmatically create his search bar. But I would like to replace this code with a search bar designed in the story board.
So my question is, how can I connect the outlet to the search controller?
this is my code:
public class CustomSearchController: UISearchController {
public var customSearchBar = UISearchBar()
override public var searchBar: UISearchBar {
get {
return self.customSearchBar
}
}
}
func configureSearchController() {
searchController = CustomSearchController()
searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = false
searchController.hidesNavigationBarDuringPresentation = false
searchController.customSearchBar = self.customSearchBar
searchController.searchBar.delegate = self
self.definesPresentationContext = true
}
extension EarthSearcherTableViewController : UISearchResultsUpdating {
public func updateSearchResults(for searchController: UISearchController) {
//Code
guard let text = searchController.searchBar.text else { return }
self.getLocations(forSearchString: text)
}
fileprivate func getLocations(forSearchString searchString: String) {
let request = MKLocalSearchRequest()
request.naturalLanguageQuery = searchString
request.region = mapView.region
let search = MKLocalSearch(request: request)
search.start { (response, error) in
guard let response = response else { return }
self.locations = response.mapItems
self.tableView.reloadData()
}
}
#objc func zoomToCurrentLocation() {
//Clear existing pins
mapView.removeAnnotations(mapView.annotations)
mapView.removeOverlays(mapView.overlays)
let annotation = MKPointAnnotation()
annotation.coordinate = mapView.userLocation.coordinate
mapView.addAnnotation(annotation)
let span = MKCoordinateSpanMake(0.005, 0.005)
let region = MKCoordinateRegionMake(mapView.userLocation.coordinate, span)
mapView.setRegion(region, animated: true)
let location = CLLocation(latitude: mapView.userLocation.coordinate.latitude, longitude: mapView.userLocation.coordinate.longitude)
mapView.add(MKCircle(center: location.coordinate, radius: 50))
}
}
I think I have a problem with the delegates, because when I type in the search bar, the results does not show off in the table
Any tips?

Subclass UISearchController and override searchBar getter to return the searchBar that you want.
public class mySearchController: UISearchController {
public var customSearchBar = UISearchBar()
override public var searchBar: UISearchBar {
get {
return customSearchBar
}
}
}
In your method, set the customSearchBar to your searchBar.
func configureSearchController() {
searchController = mySearchController()
searchController.customSearchBar = self.searchBar
//Other stuff...
}
