Retrieving object in background (Swift)

General
1

I am loading objects from the server async, I think, but the app stops and wait for the load to finish. I tried to use GDC, but that just doesn’t load the objects at all.
The function is called in the viewDidLoad.


 func findWeeksAsync() {
 UIApplication.sharedApplication().networkActivityIndicatorVisible = true
 debugPrint("Loading weeks")
 MMProgressHUD.showWithTitle("Loading")
 self.weekCollection.removeAll()
 
 let dataQuery = BackendlessDataQuery()
 let currentUser = backendless.userService.currentUser
 let whereClause = "ownerId = '\(currentUser.objectId!)'"
 
 dataQuery.whereClause = whereClause
 dataQuery.queryOptions.sortBy = ["startDate DESC"]
 
 var error: Fault?
 let weeks = backendless.data.of(FDWeek.ofClass()).find(dataQuery, fault: &error)
 if error == nil {
 for obj in weeks.data {
 let week = obj as! FDWeek
 self.weekCollection.append(week)
 }
 debugPrint("Found \(weekCollection.count) weeks")
 MMProgressHUD.dismiss()
 UIApplication.sharedApplication().networkActivityIndicatorVisible = false
 self.tableView.reloadData()
 
 } else {
 debugPrint("Server reported an error: \(error)")
 MMProgressHUD.dismissWithError("Please try later", title: "Server Error!", afterDelay: 4)
 UIApplication.sharedApplication().networkActivityIndicatorVisible = false
 }
 }

let query = BackendlessDataQuery()        
        backendless.persistenceService.of(FDWeek.ofClass()).find(
            query,
            response: { ( venues : BackendlessCollection!) -> () in
                //do what you want
                //success hide mbprogresshud
              
            },
            error: { (fault : Fault!) -> () in
                print("Server reported an error: \(fault)")
                //hide progress hud
        })
