ios - Fetching subclassed objects from Parse -

in our project, have class called attendee, inherits pfobject. run pfquery fetches list of pfobjects, want store global attendee array. below code array , our query:

var attendees: [attendee] = []

query.findobjectsinbackgroundwithblock { (objects: [anyobject]?, error: nserror?) -> void in                 if( error == nil ) {                     attendees = objects as! [attendee]                 } else {                     println( error )                 }             } 

however, when check contents of attendees array in debugger, empty. using debugger, checked objects array returned findobjectsinbackgroundwithblock, , there objects being fetched.

i've attached attendee class definition below.

class attendee: pfobject, pfsubclassing {     override class func initialize() {         var oncetoken : dispatch_once_t = 0;         dispatch_once(&oncetoken) {             self.registersubclass()         }     }      class func parseclassname() -> string {         return "attendee"     } } 

why typecast , copy attendees not working correctly? developing on swift 1.2 , xcode 6.3

you have register custom object in appdelegate:

attendee.registersubclass()

just before parse initialization parse.setapplicationid("xxx", clientkey: "xxx")

if didn't, have init pfquery attendee's class name:

let query = pfquery(classname: attendee.parseclassname()) query.fromlocaldatastore() //if data locally stored query.findobjectsinbackgroundwithblock { .. } 

these steps worked me.
