How to give suggestions based on MKmapview search in a tableview

Hello guys. Im stuck and this might be a bit over the top but i hope someone can help me.

So I have a map on my app with MKmapview. Above the app i have a search option and when the search find a place it adds a annotation to that specific place. But the search takes the last suggestion when i do a search but i want to display the different results when a user search. So the user can take that suggestion and it will go back to the map and put the annotation on that location. The code that I have right now is:

func searchBarSearchButtonClicked(searchBar: UISearchBar){

    //1
    searchBar.resignFirstResponder()
    dismissViewControllerAnimated(true, completion: nil)
    if self.mapView.annotations.count != 0{
        annotation = self.mapView.annotations[0]
        self.mapView.removeAnnotation(annotation)
    }

//2
    localSearchRequest = MKLocalSearchRequest()
    localSearchRequest.naturalLanguageQuery = searchBar.text
    localSearch = MKLocalSearch(request: localSearchRequest)
    localSearch.startWithCompletionHandler { (localSearchResponse, error) -> Void in

        if localSearchResponse == nil{
            let alertController = UIAlertController(title: nil, message: "Place Not Found", preferredStyle: UIAlertControllerStyle.Alert)
            alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.Default, handler: nil))
            self.presentViewController(alertController, animated: true, completion: nil)
            return
        }

 //3
        self.pointAnnotation = MKPointAnnotation()
        self.pointAnnotation.title = searchBar.text
        self.pointAnnotation.coordinate = CLLocationCoordinate2D(latitude: localSearchResponse!.boundingRegion.center.latitude, longitude:     localSearchResponse!.boundingRegion.center.longitude)


        self.pinAnnotationView = MKPinAnnotationView(annotation: self.pointAnnotation, reuseIdentifier: nil)
        self.mapView.centerCoordinate = self.pointAnnotation.coordinate
        self.mapView.addAnnotation(self.pinAnnotationView.annotation!)
        self.mapItemData = localSearchResponse?.mapItems.last
    }
}

Im guessing that i should exchange the last part self.mapItemData = localSearchResponse?.mapItems.last with like a for loop like this maybe: ```for item in localSearchResponse!.mapItems { // add to a tableView }

But i dont know how to add a tableview or how to display the information. If anyone can help i will love you forever.
