title: didSelectAnnotationView not called
body: <p>I would like to work with an annotation once it's clicked. I've looked it up on the documentation of Apple and I did googled but I can not find why this is any different than how it should be done.
  Basically; I don't get a <code>println("Pin clicked");</code></p>
  
  <p>Why not?</p>
  
  <pre><code>    func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -&gt; MKAnnotationView!
  {
      if !(annotation is MKPointAnnotation) {
  
          return nil
      }
  
      let reuseId = "test"
  
      var anView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId)
      if anView == nil {
          anView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
          anView.canShowCallout = true
  
      }
      else {
          anView.annotation = annotation
      }
  
      return anView
  }
  func mapView(mapView: MKMapView!, didSelectAnnotationView view: MKAnnotationView!)
  {
      println("Pin clicked");
  }
  func setAnnotationPinOnMap(annotation : NSManagedObject)
  {
  
      var subject: AnyObject? = annotation.valueForKey("subject")
      var desc: AnyObject? = annotation.valueForKey("desc")
      var langitude: AnyObject? = annotation.valueForKey("langitude")
      var longitude: AnyObject? = annotation.valueForKey("longitude")
      println(annotation);
      let pin = MKPointAnnotation()
  
      let location = CLLocationCoordinate2D(
          latitude: longitude as CLLocationDegrees,
          longitude: langitude as CLLocationDegrees
      )
      println(location.longitude, location.latitude)
      pin.setCoordinate(location)
      pin.title = subject as String!
      pin.subtitle = desc as String!
      println( pin.coordinate.longitude)
      viewForAnnotation(pin);
      mapView.addAnnotation(pin)
  }
  </code></pre>
  
  <p>I have imported map kit and included the map view delegate.</p>
