How to create a model class for the following JSON data and parse it?

My JSON data

{
 "addon_items" : [
                     {
                      "aname" : "",
                      "id" : "2588",
                      "name" : "Plain Nan",
                      "order" : "1",
                      "aid" : "259",
                      "Sub_Add_Items" : "",
                      "icon" : "",
                      "status" : "1",
                      "next" : "0",
                      "price" : "0.60"
                     },
                     {
                      "aname" : "",
                      "id" : "2589",
                      "name" : "Pitta Bread",
                      "order" : "2",
                      "aid" : "259",
                      "Sub_Add_Items" : "",
                      "icon" : "",
                      "status" : "1",
                      "next" : "0",
                      "price" : "0.00"
                    }

                   ],

 "addon" : {
             "description" : "Please choose your Nan bread",
             "aname" : "",
             "id" : "259",
             "icon" : "",
             "limit" : "1",
             "special_addon" : "",
             "next" : "165"
           }
 }

I created three class models called AddOnResponse, AddOn, AddOnItems as follows:

Class model AddOnResponse

class AddOnResponse {

var addon: Array<String>?
var addonitems: Array<AnyObject>?

init(addon:Array<String>?,addonitems: Array<AnyObject>?){
    self.addon = addon
    self.addonitems = addonitems
 }
}

Class model AddOn

class AddOn {


var id: Int?
var icon: String?
var desc: String?
var limit: Int?
var next: Int?
var aname: String?
var specialaddon: Int?

init(id: Int?,icon: String?,desc: String?,limit: Int?,next: Int?,aname: String?,specialaddon: Int?){

    self.id = id
    self.icon = icon
    self.desc = desc
    self.limit = limit
    self.next = next
    self.aname = aname
    self.specialaddon = specialaddon

  }
 }

Class model AddOnItems

class AddOnItems {


var id: Int?
var aid: Int?
var name: String?
var price: Int?
var order: Int?
var status: Int?
var next: Int?
var aname: String?
var subaddItems: Int?
var icon: String?

init(id: Int?,aid: Int?,name: String?,price: Int?,order: Int?,status: Int?,next: Int?,aname: String?,subaddItems: Int?,icon: String?){
    self.id = id
    self.aid = aid
    self.name = name
    self.price = price
    self.order = order
    self.status = status
    self.next = next
    self.aname = aname
    self.subaddItems = subaddItems
    self.icon = icon
   }
 }

Now I retrieve my JSON data using Alamofire, but when I take dat into a cool model using an object, I get a null value.

    var addonResponses = [AddOnResponse]()

    Alamofire.request(.GET, myAddOnUrl)
        .validate()
        .responseJSON
        {   response in
            switch response.result
            {
            case .Success:
                if let value = response.result.value{
                    let json = JSON(value)
                    print(json)
                    print(json["addon"].arrayValue)


           for(_,content) in json{
               let addOnRes = AddOnResponse(addon:content["addon"].arrayValue,
                               addonitems:content["addon_items"].Arrayobject)

                        print(self.addonResponses.count)
                        print(addOnRes.addon)
                        print(addOnRes.addonitems)
                    }
                }

The addon and addonitems data goes to zero, why?
