ios - Issue Saving/Displaying CKAssets -

i'm pretty new swift, please try bear me.

i'm able download ckrecords , insert them array, "birdfacts". each record includes few strings, image (ckasset), date, , int. when download icloud, works fine.

everything saving expected, except image. when reload data, asset doesn't show up.

here code load saved data:

    if let savedfacts = loadfacts() {         birdfacts = savedfacts         print("successfully loaded saved bird facts")     }  func loadfacts() -> [ckrecord]? {     return nskeyedunarchiver.unarchiveobjectwithfile(birdfact.archiveurl.path!) as? [ckrecord] } 

this code save array:

func savefacts() {     let issuccessfulsave = nskeyedarchiver.archiverootobject(birdfacts, tofile: birdfact.archiveurl.path!)     if !issuccessfulsave {         print("failed save bird facts")     } } 

this within custom class definition file:

import uikit import cloudkit  class birdfact: nsobject, nscoding { //mark: properties var birdname: string  var photo: ckasset  var birdfact: string  var date: nsdate  var sortingdate: int  //mark: types struct propertykey {     static let namekey = "name"     static let photokey = "photo"     static let factkey = "fact"     static let datekey = "date"     static let sortingdatekey = "sortingdate" }  //mark: initialization  init?(birdname: string, photo: ckasset, birdfact: string, date: nsdate, sortingdate: int){     //init stored props     self.birdname = birdname     self.photo = photo     self.birdfact = birdfact     self.date = date     self.sortingdate = sortingdate      super.init()      if birdname.isempty || birdfact.isempty {         return nil     } }  //mark: nscoding func encodewithcoder(acoder: nscoder) {     acoder.encodeobject(birdname, forkey: propertykey.namekey)     acoder.encodeobject(photo, forkey: propertykey.photokey)     acoder.encodeobject(birdfact, forkey: propertykey.factkey)     acoder.encodeobject(date, forkey: propertykey.datekey)     acoder.encodeobject(sortingdate, forkey: propertykey.sortingdatekey) }  required convenience init?(coder adecoder: nscoder) {     let birdname = adecoder.decodeobjectforkey(propertykey.namekey) as! string     let photo = adecoder.decodeobjectforkey(propertykey.photokey) as! ckasset     let birdfact = adecoder.decodeobjectforkey(propertykey.factkey) as! string     let date = adecoder.decodeobjectforkey(propertykey.datekey) as! nsdate     let sortingdate = adecoder.decodeobjectforkey(propertykey.sortingdatekey) as! int      self.init(birdname: birdname, photo: photo, birdfact: birdfact, date: date, sortingdate: sortingdate) }  //mark: archiving paths static let documentsdirectory = nsfilemanager().urlsfordirectory(.documentdirectory, indomains: .userdomainmask).first! static let archiveurl = documentsdirectory.urlbyappendingpathcomponent("birdfacts") 

}

i'm saving whenever finish downloading , sorting records. idea going wrong?

edit: included cloudkit query. should note never save icloud, download existing records.
