How can I add multiple annotations on a map using GPS coordinates with Swift?
<p>I am new to Swift. I was following a tutorial to make an annotation on a map. I successfully made one annotation, thats as far as the tutorial went... I've been looking around trying to find how to make multiple annotations using Swift and can't find it. </p>

<p>How can I make multiple annotations on the map?
Thanks.</p>

<p><strong><em>Here is my code from viewcontroller.swift:</em></strong></p>

<pre><code>import UIKit
import MapKit

class ViewController: UIViewController, MKMapViewDelegate {

    @IBOutlet var map: MKMapView!  
    override func viewDidLoad() {
        super.viewDidLoad()


        //setting the map region
        let latitude: CLLocationDegrees = 33.606800
        let longitude: CLLocationDegrees = -111.845360
        let latDelta: CLLocationDegrees = 0.01
        let lonDelta: CLLocationDegrees = 0.01
        let span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)
        let location:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
        let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)
        map.setRegion(region, animated: true)

        //map annotation
        let annotation = MKPointAnnotation()
        annotation.coordinate = location
        annotation.title = "Taliesin West"
        annotation.subtitle = "Design"
        map.addAnnotation(annotation)        

        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}
