Порядок значений снимка изменяется SwiftyJSON, возвращая [null, nulll, .... items]

Question

Я использую Firebase, я делаю запрос и получаю данные. Затем охватывая JSON, после этого мой JSON порядок данных изменился, не в чем проблема, я не хочу, чтобы порядок изменился.

Какое решение сделать тот же заказ здесь мои данные

//Query Applied
  pathref.queryOrderedByKey().queryStarting(atValue: fromItemKey).queryLimited(toFirst: UInt(paginationCount)).observe(.value, with: { (snapshot) in {

     print(" json obj=====",snapshot.value  )
    // all order is correct 

     let jsonData = try JSONSerialization.data(withJSONObject: bizOfferingsSnapshot.value as Any, options: .prettyPrinted)

     let offeringJson = try JSON(data: jsonData)

    // here order is changed 
      print(" json obj=====",offeringJson  )
        }
