viewForAnnotation not being called (using Alamofire to parse JSON) - swift

Question

I'm new to iOS programming. I prefer to use Swift.
What I'm trying to do is call a web service that returns some JSON, parse the JSON into a custom object called Entry and plot those entries on a map.
I am using AlamoFire to make the web service call and SwiftyJSON to parse the JSON into Entry objects like below
request(.GET, URLString: "https://myURLThatReturnsJson")
.responseJSON { (_, _, json, error) in
if let json: AnyObject = json{
let jsonEntries = JSON(json)
for result in jsonEntries["entries"].arrayValue {
let business_name = result["business_name"].stringValue
let latitude = result["lat"].stringValue
let longitude = result["lng"].stringValue
let category = result["category"].stringValue
let address = result["address"].stringValue
let city = result["city"].stringValue
let type = result["type"].stringValue
let location = result["location"].stringValue
let valid = result["valid"].stringValue
let comments = result["comments"].stringValue
let date = result["date"].stringValue
let username = result["username"].stringValue
let additional_comment_count = result["additional_comment_count"].stringValue
let entry : Entry = Entry(
business_name: business_name,
latitude: latitude,
longitude: longitude,
category: category,
address: address,
city: city,
type: type,
location: location,
valid: valid,
comments: comments,
date: date,
username: username,
additional_comment_count: additional_comment_count,
title: business_name,
subtitle: location,
coordinate: CLLocationCoordinate2D(latitude: (latitude as NSString).doubleValue, longitude: (longitude as NSString).doubleValue))
entries.append(entry)
}
// Now we have our array of entries. Now plot them.
for entry in entries{
self.mapView.addAnnotation(entry)
}
}
}
So as you can see in the code above I am also mapping the entries within the AlamoFire request (don't know if this is bad because AlamoFire is done on a separate thread I believe).
I also have a viewForAnnotations method that looks like below
func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
print("viewForAnnotation called")
return nil
}
My viewForAnnotation method is not being called at all (break point on print line is not being hit).
Any help is appreciated!

Please make sure to set the delegate property of mapview to self.
mapview.delegate = self
You can also do this by connecting the delegate outlet of mapview to ViewController using Connection Inspector (Interface Builder)
