mapView(_:viewForAnnotation:)- pinColor - Change the pin color on the map

Update April 11, 2016:
Draw the map and pin programmatically in Swift 2.2 with Xcode 7.3.

import UIKit

import MapKit

class ViewController: UIViewController, MKMapViewDelegate {

    

    override func viewDidLoad() {

        super.viewDidLoad()

        

        let point = MKPointAnnotation()

        point.coordinate = CLLocationCoordinate2DMake(25.0305, 121.5360)

        point.title = "Taipei"

        point.subtitle = "Taiwan"

        

        let myMap = MKMapView(frame: CGRectMake(0,20, view.frame.width, view.frame.height-20))

        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {

            

            dispatch_async(dispatch_get_main_queue()) {

                myMap.addAnnotation(point)

                print("addAnnotation")

            }

        }

        myMap.centerCoordinate = point.coordinate

        myMap.delegate = self

        

        //Span of the map

        myMap.setRegion(MKCoordinateRegionMake(myMap.centerCoordinate, MKCoordinateSpanMake(0.2,0.2)), animated: true)

        

        view.addSubview(myMap)

        print("addSubview(myMap)")

    }

    

    func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {

        

        let annotationView = MKPinAnnotationView()

        annotationView.pinTintColor = UIColor.orangeColor()

        

        print("Pin Color Set")

        

        return annotationView

    }

    

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

    }

}

Result:

Debug Console:

addSubview(myMap)
addAnnotation
Pin Color Set

Simulator:
