I am working on a app using

now have an issue kindly help me to figure out.

  • I placed a search bar when user types the name of a place then it gives suggestions based upon the string entered.

  • Using mapkit, I am able to send query to default maps, receive MKLocalSearchResponse.

Now My problem is data from LocalSearchResponse is not getting displayed in tableView cells.

please kindly provide an solution.

Using tools: Xcode 7.3, swift 2.2

Here is my code kindly have a look.

import UIKit
import MapKit
class ViewController: UIViewController, UISearchBarDelegate,UITableViewDelegate {

var searchController:UISearchController!
var annotation:MKAnnotation!
var localSearchRequest:MKLocalSearchRequest!
var localSearch:MKLocalSearch!
var localSearchResponse:MKLocalSearchResponse!
var items1:String = ""

var error:NSError!
var pointAnnotation:MKPointAnnotation!
var pinAnnotationView:MKPinAnnotationView!
var matchingItems: [MKMapItem] = [MKMapItem]()
var mapItems: [MKMapItem] = [MKMapItem]()
var itm : [String] = []

@IBAction func showSearchBar(sender: AnyObject) {
searchController = UISearchController(searchResultsController: nil)
searchController.hidesNavigationBarDuringPresentation = false
self.searchController.searchBar.delegate = self
presentViewController(searchController, animated: true, completion: nil)


@IBOutlet var mapView: MKMapView!

override func viewDidLoad() {
// Do any additional setup after loading the view, typically from a nib.

override func didReceiveMemoryWarning() {
// Dispose of any resources that can be recreated.

func searchBarSearchButtonClicked(searchBar: UISearchBar){

dismissViewControllerAnimated(true, completion: nil)
if self.mapView.annotations.count != 0{
annotation = self.mapView.annotations[0]

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)

for item in localSearchResponse!.mapItems {

print("Name = \(")
self.items1 =!

self.matchingItems.append(item as MKMapItem)
print("Matching items = \(self.matchingItems.count)")
self.pointAnnotation = MKPointAnnotation()
self.pointAnnotation.title = searchBar.text
self.pointAnnotation.coordinate = CLLocationCoordinate2D(latitude: localSearchResponse!, longitude: localSearchResponse!

self.pinAnnotationView = MKPinAnnotationView(annotation: self.pointAnnotation, reuseIdentifier: nil)
self.mapView.centerCoordinate = self.pointAnnotation.coordinate

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return matchingItems.count

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) ->UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! UITableViewCell
let entry = matchingItems[indexPath.row]
cell.textLabel!.text = items1[indexPath.row]

return cell


Answer Source
  1. set the delegate and datasource of your tableView to the associated viewController using the storyboard properly see image
  2. Add delegate and datasuorce both seprating with comma like UITableViewDataSource, UITableViewDelegate in your class.

enter image description here

now you dont need to set the delegate inside the program.

  • call reloadData() function each and everytime when you type a single word or accordingly.
