Map with Photos using Parse

Question

I'm trying to do exactly this using Parse and Swift.

import UIKit
import MapKit
import CoreLocation

class MapViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {

var latitude:Double = 0.0
var longitude:Double = 0.0

@IBOutlet var map: MKMapView!


override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.setNavigationBarHidden(true , animated: true)
    self.map.showsUserLocation = true
    self.map.delegate = self


    PFGeoPoint.geoPointForCurrentLocationInBackground { (geopoint:PFGeoPoint?, error:NSError?) -> Void in

        var query = PFQuery(className: "Locations")
        query.whereKey("geopoint", nearGeoPoint: geopoint!)
        query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in

            if let myObjects = objects {

                for object in myObjects {

                    var thePoint: PFGeoPoint = object["geopoint"] as! PFGeoPoint
                    self.latitude = thePoint.latitude
                    self.longitude = thePoint.longitude
                    NSLog(" Hej %f, %f", self.latitude, self.longitude)
                    var annotationCoordinate: CLLocationCoordinate2D = CLLocationCoordinate2DMake(self.latitude, self.longitude)
                    var annotation = MKPointAnnotation()
                    annotation.coordinate = annotationCoordinate
                    annotation.title = object["discovery"] as! String
                    annotation.subtitle = object["location"] as! String
                    self.map.addAnnotation(annotation)

                }
            }
        }
    }
}

Big picture though, I'm trying to create a way to access pictures stored on Parse (and their locations) and display them on a map if they meet my query. I greatly appreciate any help!

if you are getting the conversion error in

var thePoint: PFGeoPoint = object["geopoint"]

change it to

var thePoint: PFGeoPoint = object["geopoint"] as! PFGeoPoint

Regarding converting Double to Int, it appears to be as you found but I don't know the rationale behind the decision by the designers of swift. I would like to understand why you need the conversion since there may be an alternate implementation

I've updated my original code based on your comment. I'm now able to build without any errors! I'm still working on getting to the point where I have a map with photos. Thank you for your help. – Emile Frey May 22 '15 at 02:43
