解析数据返回nil

Question

我当前的代码在解析数据的id时返回nil。 “结果”是存储所有数据的字典，“id”是我需要的，我的代码是否正确？有关为何返回nil的任何解决方案？：

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

有人可以帮我解决如何解析用户在我的应用中创建订单时生成的数据的ID吗？

我是否以数据中的区域为目标来提取我需要的数据？
