Robs example for Swift 3:

class MapViewController: UIViewController
{
    override func viewDidLoad()
    {
        super.viewDidLoad()

        // Create map view in storyboard
        view.delegate = self
    }
}

extension MapViewController: MKMapViewDelegate
{
    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView?
    {
        let annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "annotationView")
        annotationView.canShowCallout = true
        annotationView.rightCalloutAccessoryView = UIButton.init(type: UIButtonType.detailDisclosure)

        return annotationView
    }

    func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl)
    {
        guard let annotation = view.annotation else
        {
            return
        }

        let urlString = "http://maps.apple.com/?sll=\(annotation.coordinate.latitude),\(annotation.coordinate.longitude)"
        guard let url = URL(string: urlString) else
        {
            return
        }

        UIApplication.shared.openURL(url)
    }
}
