Converting Parse PFGeoPoint into an annotation on the map - swift

Question

I am trying to convert a saved PFGeopoint objects in Parse server into an annotation but i can't seem to figure it out and i don't know what's wrong.
I tried to apply the code from this question : Converting Parse GeoPoint into a CLLocation in Swift but i still couldn't figure it out.
Here is my Code :
import UIKit
import MapKit
import CoreLocation
import Parse
class MapVC: UIViewController, MKMapViewDelegate {
fileprivate let locationManager = CLLocationManager()
fileprivate var startedLoadingPOIs = false
fileprivate var places = [Place]()
var descLocation: PFGeoPoint = PFGeoPoint()
var mapHasCenteredOnce = false
#IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
mapView.delegate = self
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
locationManager.startUpdatingLocation()
locationManager.requestWhenInUseAuthorization()
mapView.userTrackingMode = MKUserTrackingMode.followWithHeading
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
var annotationView: MKAnnotationView?
if annotation.isKind(of: MKUserLocation.self) {
annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "User")
annotationView?.image = UIImage(named: "loc.png")
}
return annotationView
}
}
extension MapVC: CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
//1
if locations.count > 0 {
let location = locations.last!
print("Accuracy: \(location.horizontalAccuracy)")
//2
if location.horizontalAccuracy < 100 {
//3
manager.stopUpdatingLocation()
let span = MKCoordinateSpan(latitudeDelta: 0.014, longitudeDelta: 0.014)
let region = MKCoordinateRegion(center: location.coordinate, span: span)
mapView.region = region
if !startedLoadingPOIs {
startedLoadingPOIs = true
let loader = PlacesLoader()
loader.loadPOIS(location: location, radius: 1000) { placesDict, error in
if let dict = placesDict {
let query = PFQuery(className: "posts")
if let latitude = (PFUser.current()?["location"] as AnyObject).latitude {
if let longitude = (PFUser.current()?["location"] as AnyObject).longitude {
let geoPoint = PFGeoPoint(latitude: latitude, longitude: longitude)
query.whereKey("postLocation", nearGeoPoint: geoPoint, withinKilometers: 1)
}
}
query.findObjectsInBackground { (objects: [PFObject]?, error: Error?) in
if error == nil {
for object in objects! {
let pfObject = object as PFObject
let caption = pfObject["title"] as! String
self.descLocation = object["postLocation"] as! PFGeoPoint
let latitude: CLLocationDegrees = self.descLocation.latitude
let longitude: CLLocationDegrees = self.descLocation.longitude
let location = CLLocation(latitude: latitude, longitude: longitude)
let place = Place(location: location, name: caption )
self.places.append(place)
let annotation = PlaceAnnotation(location: place.location!.coordinate, title: place.placeName)
DispatchQueue.main.async {
self.mapView.addAnnotation(annotation)
}
}
}
}
}
}
}
}
}
}
}

I just had two uanessacry lines that blocked the operation, removed them and it worked for me.
loader.loadPOIS(location: location, radius: 1000) { placesDict, error in
if let dict = placesDict {
