In Alamofire only the UINavigationController is called! no other response

Question

I am using this tutorial to auto-complete the google places.

I have installed the alamofire and swiftyJSON through cocoapads.

My issue is When I enter text in searchbar, nothing happens.

On my ViewControlller:

    let gpaViewController = GooglePlacesAutocomplete(
    apiKey: "MY-API-KEY",
    placeType: .Address
    )

    gpaViewController.placeDelegate = self

    presentViewController(gpaViewController, animated: true, completion: nil)

On my GooglePlacesAutoComplete View Controller:

import UIKit
import Alamofire
import SwiftyJSON

enum PlaceType: CustomStringConvertible {
case All
case Geocode
case Address
case Establishment
case Regions
case Cities

var description : String {
    switch self {
    case .All: return ""
    case .Geocode: return "geocode"
    case .Address: return "address"
    case .Establishment: return "establishment"
    case .Regions: return "regions"
    case .Cities: return "cities"
    }
}
}

struct Place {
    let id: String
    let description: String
}

protocol GooglePlacesAutocompleteDelegate {
    func placeSelected(place: Place)
    func placeViewClosed()
}    

Only this set of codes is called:

class GooglePlacesAutocomplete: UINavigationController {

var gpaViewController: GooglePlacesAutocompleteContainer?

var placeDelegate: GooglePlacesAutocompleteDelegate? {
    get { return gpaViewController?.delegate }
    set { gpaViewController?.delegate = newValue }
}

convenience init(apiKey: String, placeType: PlaceType = .All) {
    let gpaViewController = GooglePlacesAutocompleteContainer(
        apiKey: apiKey,
        placeType: placeType
    )

    self.init(rootViewController: gpaViewController)
    self.gpaViewController = gpaViewController

    let closeButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Stop, target: self, action: "close")

    gpaViewController.navigationItem.leftBarButtonItem = closeButton
    gpaViewController.navigationItem.title = "Enter Address"
}

func close() {
    placeDelegate?.placeViewClosed()
}

}

No indication of this:

class GooglePlaceSearchDisplayController: UISearchDisplayController {
override func setActive(visible: Bool, animated: Bool) {
    if active == visible { return }

    searchContentsController.navigationController?.navigationBarHidden = true
    super.setActive(visible, animated: animated)

    searchContentsController.navigationController?.navigationBarHidden = false

    if visible {
        searchBar.becomeFirstResponder()
    } else {
        searchBar.resignFirstResponder()
    }
}
}
// MARK: - GooglePlacesAutocompleteContainer
class GooglePlacesAutocompleteContainer: UIViewController {
    var delegate: GooglePlacesAutocompleteDelegate?
    var apiKey: String?
    var places = [Place]()
    var placeType: PlaceType = .All

convenience init(apiKey: String, placeType: PlaceType = .All) {
    self.init(nibName: "GooglePlacesAutocomplete", bundle: nil)
    self.apiKey = apiKey
    self.placeType = placeType
}

override func viewDidLoad() {
    super.viewDidLoad()

    let tv: UITableView? = searchDisplayController?.searchResultsTableView
    tv?.registerClass(UITableViewCell.self, forCellReuseIdentifier: "Cell")

}

}

Or this:

// MARK: - GooglePlacesAutocompleteContainer (UITableViewDataSource / UITableViewDelegate)
extension GooglePlacesAutocompleteContainer: UITableViewDataSource, UITableViewDelegate {
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return places.count
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = self.searchDisplayController?.searchResultsTableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell?

    // Get the corresponding candy from our candies array
    let place = self.places[indexPath.row]

    // Configure the cell
    cell!.textLabel!.text = place.description
    cell!.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator

    return cell!
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    delegate?.placeSelected(self.places[indexPath.row])
}
}

// MARK: - GooglePlacesAutocompleteContainer (UISearchDisplayDelegate)
 extension GooglePlacesAutocompleteContainer: UISearchDisplayDelegate {
    func searchDisplayController(controller: UISearchDisplayController, shouldReloadTableForSearchString searchString: String!) -> Bool {
    getPlaces(searchString)
    return false
}

private func getPlaces(searchString: String) {
    let url = "https://maps.googleapis.com/maps/api/place/autocomplete/json"
    Alamofire.request(.GET, url).responseJSON { response in
        switch response.result {
        case .Success(let data):
            let json = JSON(data)
            let name = json["name"].stringValue
            print(name)
        case .Failure(let error):
            print("Request failed with error: \(error)")
        }
    }
}
}

Apologies for long code. Am not sure, where I made a mistake. I also set the delegate for searchBar in xib I double checked the installation of Cocoapads, Alamofire and SwiftyJson. Can someone please help me? I'm new to these things..

You Have To Make Object Of UISearchBar Like This...

lazy var searchBar : UISearchBar = UISearchBar()

In Did Load

searchBar.delegate = self
