解析JSON返回nil

Question

我正在使用此代碼在購物車中訂購產品。 我正在嘗試獲取所生成訂單的訂單ID。 我不太確定發生了什么，因為“結果”是AnyHashable值，ID是我需要的值。 運行代碼后，它始終顯示nil嗎？

Moltin.sharedInstance().cart.order(withParameters: orderParameters, success: { (responceDictionary) -> Void in
    print(responceDictionary)

    let orderID1 = responceDictionary!["result.id"] as? String
    let orderID = orderID1

    print(orderID)

我正在嘗試解析此數據：

您不能將密鑰路徑傳遞給密鑰訂閱，並且id是Int：

if let resultDictionary = responceDictionary["result"] as? [String:Any],
   let orderID = resultDictionary["id"] as? Int {
       let orderIDString = "\(orderID)"
       print(orderIDString)
}
