Annotations won't appear on MapView - ios

Question

I'm having trouble getting my annotations to display on my map view. Nothing is displaying right now. What is wrong with my code ?
Here is my base map view controller:
import UIKit
import MapKit
import CoreLocation
class MapViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate {
let goldenWordsYellow = UIColor(red: 247.00/255.0, green: 192.00/255.0, blue: 51.00/255.0, alpha: 0.5)
// Map View outlet declaration
#IBOutlet weak var mapView: MKMapView!
// Hamburger button declaration
#IBOutlet weak var menuButton:UIBarButtonItem!
var locationManager: CLLocationManager?
/* Really ugly code where I declare all of my static data */

Here is my map view controller extension:
import Foundation
import MapKit
extension MapViewController {
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if let annotation = annotation as? IssueLocation {
let identifier = "pin"
var view: MKPinAnnotationView
if let dequeuedView = mapView.dequeueReusableAnnotationViewWithIdentifier(identifier) as? MKPinAnnotationView {
dequeuedView.annotation = annotation // NOTE: 2 options here for the "annotation" at the end of this line. I choose the first one but am in doubt.
view = dequeuedView
} else {
view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier) // NOTE: another unsure choice for the "annotation" right before the comma
view.canShowCallout = true
view.calloutOffset = CGPoint(x: -5, y: 5)
view.rightCalloutAccessoryView = UIButton(type: UIButtonType.DetailDisclosure) as UIView
}
return view
}
return nil
}
func mapView(mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
let location = view.annotation as! IssueLocation
let launchOptions = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeWalking]
location.mapItem().openInMapsWithLaunchOptions(launchOptions)
}
}
And here is my class:
import Foundation
import MapKit
import AddressBook
import Contacts
class IssueLocation: NSObject, MKAnnotation {
let locationName: String
let coordinate: CLLocationCoordinate2D
init(locationName: String, coordinate: CLLocationCoordinate2D) {
self.locationName = locationName
self.coordinate = coordinate
super.init()
}
var subtitle: String? {
return locationName
}
var title: String? {
return locationName
}
func mapItem() -> MKMapItem {
let addressDictionary = [String(CNPostalAddressStreetKey): locationName]
let placemark = MKPlacemark(coordinate: coordinate, addressDictionary: addressDictionary)
let mapItem = MKMapItem(placemark: placemark)
mapItem.name = locationName
return mapItem

This issue is with your coordinates.
Your code:
let coordinatesARC = IssueLocation(locationName: "ARC", coordinate: CLLocationCoordinate2D(latitude: -76.49416565895079, longitude: 44.22928743712073))
let coordinatesJDUC = IssueLocation(locationName: "JDUC", coordinate: CLLocationCoordinate2D(latitude: -76.49507761001587, longitude: 44.22838027067406))
Corrected code:
let coordinatesARC = IssueLocation(locationName: "ARC", coordinate: CLLocationCoordinate2D(latitude: 44.22928743712073, longitude: -76.49416565895079))
let coordinatesJDUC = IssueLocation(locationName: "JDUC", coordinate: CLLocationCoordinate2D(latitude: 44.22838027067406, longitude: -76.49507761001587))
