Ios Google Map Cluster item click event not work - ios

Question

I am working with Google Map for IOS .Where i have implemented clustering but cluster and cluster item marker click event not work . But individual google map marker click event is working .
Here is my full code
import UIKit
import GoogleMaps
import Alamofire
import SwiftyJSON
let kCameraLatitude = 22.3475
let kCameraLongitude = 91.8123
/// Point of Interest Item which implements the GMUClusterItem protocol.
class POIItem: NSObject, GMUClusterItem {
var position: CLLocationCoordinate2D
var currencies = "currencies";
var phone = "phone";
var dateTime = "dateTime";
var location = "location";
var link = "link";
var exchangeLimits = "exhangeLimits";
var id = "id";
var updated_at = "updated";
var operationName = "opeationName";
var email = "email";
var address = "address";
var createdAt = "createdAt";
var workingDays = "workingDays";
var longitude = "longitude";
var latitude = "latitude";
var exchange = "exChange";
init(position: CLLocationCoordinate2D, operationName: String) {
self.position = position
self.operationName = operationName
}
}
class FirstViewController: UIViewController , GMUClusterManagerDelegate, GMSMapViewDelegate{
private var mapView: GMSMapView!
private var clusterManager: GMUClusterManager!
override func loadView() {
let camera = GMSCameraPosition.camera(withLatitude: kCameraLatitude,
longitude: kCameraLongitude, zoom: 6)
mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
mapView.delegate = self
self.view = mapView
}
override func viewDidLoad() {
super.viewDidLoad()
// Set up the cluster manager with default icon generator and renderer.
let iconGenerator = GMUDefaultClusterIconGenerator()
let algorithm = GMUNonHierarchicalDistanceBasedAlgorithm()
let renderer = GMUDefaultClusterRenderer(mapView: mapView, clusterIconGenerator: iconGenerator)
clusterManager = GMUClusterManager(map: mapView, algorithm: algorithm, renderer: renderer)
getAllMapsData()
clusterManager.cluster()
// Register self to listen to both GMUClusterManagerDelegate and GMSMapViewDelegate events.
clusterManager.setDelegate(self, mapDelegate: self)
}
func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) {
print("You tapped at \(coordinate.latitude), \(coordinate.longitude)")
var alert = UIAlertController(title: "Choose Media type" , message: "post any" , preferredStyle: .actionSheet);
var photos = UIAlertAction(title : "Photos" , style: .default , handler: nil)

alert.addAction(photos)
alert.addAction(videos)

print("clicked cluster")
} else {
NSLog("Did tap a normal marker")
print("clicked marker")
}
return false
}

Was working on this today and also tried the same function and found it wasn't working because it was the wrong one. Instead of:
func clusterManager(clusterManager: GMUClusterManager, didTapCluster cluster: GMUCluster) {
let newCamera = GMSCameraPosition.camera(withTarget: cluster.position,
zoom: mapView.camera.zoom + 1)
let update = GMSCameraUpdate.setCamera(newCamera)
mapView.moveCamera(update)
}
Try this one: (it looks almost the same as the one above except it has a return type of Bool).
func clusterManager(_ clusterManager: GMUClusterManager, didTap cluster: GMUCluster) -> Bool {
let newCamera = GMSCameraPosition.camera(withTarget: cluster.position,
zoom: mapView.camera.zoom + 1)
let update = GMSCameraUpdate.setCamera(newCamera)
mapView.moveCamera(update)
return false
}
