How to find location of a pinned item using MapKit and Swift - ios

Question

I used MapKit's localsearch feature to generate annotation pins of whatever was typed into a search bar. I am now having trouble finding the address of those pinned locations. this is my code for the local search
func performSearch() {
matchingItems.removeAll()
let request = MKLocalSearchRequest()
request.naturalLanguageQuery = searchText.text;
request.region = attractionsMap.region;
let search = MKLocalSearch(request: request)
search.startWithCompletionHandler({(response:
MKLocalSearchResponse!,
error: NSError!) in
if error != nil {
println("Error occured in search: \(error.localizedDescription)")
} else if response.mapItems.count == 0 {
println("No matches found")
} else {
println("Matches found")
for item in response.mapItems as! [MKMapItem] {
println("Name = \(item.name)")
println("Phone = \(item.phoneNumber)")
matchingItems.append(item as MKMapItem)
println("Matching items = \(matchingItems.count)")
var annotation = MKPointAnnotation()
annotation.coordinate = item.placemark.coordinate
annotation.title = item.name
self.attractionsMap.addAnnotation(annotation)
}
}
})
}
This is my viewForAnnotation method:
extension AttractionsVC: MKMapViewDelegate {
func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
if(annotation is MKUserLocation) {
return nil;
}
let reuseId = "pin";
var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) as? MKPinAnnotationView;
if(pinView == nil) {
pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId);
pinView!.canShowCallout = true;
pinView!.animatesDrop = true;
}
var moreInfoButton = UIButton.buttonWithType(UIButtonType.DetailDisclosure) as! UIButton;
pinView?.rightCalloutAccessoryView = moreInfoButton;
return pinView;
}
I would now like to be able to display the address on the annotation. Any thoughts would be greatly appreciated.

I still don't understand what it is you want. Sometimes you ask about the address, sometimes you ask about the location.
The location is the latitude and longitude
It is the annotation's coordinate property.
The address is the human postal address
When you called
let search = MKLocalSearch(request: request)
search.startWithCompletionHandler( // ...
...you got back MKMapItems:
for item in response.mapItems as! [MKMapItem] {
Inside each MKMapItem was a placemark (an MKPlacemark, the MKMapItem's placemark property). Inside each placemark was the address information — an MKPlacemark is a CLPlacemark, so consult the CLPlacemark document for how to extract the address info.
Well, you appended each MKMapItem to an array:
matchingItems.append(item as MKMapItem)
That's where the MKMapItems are, unless you've thrown them away; so that's where the address information is.
