Using Annotations In Swift - .addAnnotation() Not Working

I am using the

MapKit
and I am receiving the following error:

enter image description here

The
locations.count?
is not working even when I am putting that in as the argument. It says that it doesn't allow
Int
as a parameter. I'm not too sure why this isn't working.

import UIKit
import MapKit

class MapViewController: UIViewController, MKMapViewDelegate {

@IBOutlet weak var myMapView: MKMapView!

override func viewDidLoad() {
super.viewDidLoad()

let italy = MKPointAnnotation()
italy.coordinate = CLLocationCoordinate2D(latitude: 41.8947400, longitude: 12.4839000)
italy.title = "Rome, Italy"

let england = MKPointAnnotation()
england.coordinate = CLLocationCoordinate2D(latitude: 51.5085300, longitude: -0.1257400)
england.title = "London, England"

let norway = MKPointAnnotation()
norway.coordinate = CLLocationCoordinate2D(latitude: 59.914225, longitude: 10.75256)
norway.title = "Oslo, Norway"

let spain = MKPointAnnotation()
spain.coordinate = CLLocationCoordinate2D(latitude: 40.41694, longitude: -3.70081)
spain.title = "Madrid, Spain"

let locations = [italy, england, norway, spain]

myMapView.addAnnotation(locations)
}

func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
let pin = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "pinIdentifier")
pin.canShowCallout = true
return pin
}
}

Answer

It should be:

myMapView.addAnnotations(locations) //note the "s"
