我正在学习Swift 4的一些新内容，并且正在尝试在API和jsonDecode上发短信。
从我一直在阅读和观看的内容中，添加了我的课程，但是我遇到了一个问题，该问题似乎很难找到答案，并且是带有名称的嵌套json。
下面是我的课（故事）：
import Foundation
class Story: Codable{
let item: Item
}
struct Item: Codable{
let featured: Int
let id: Int
struct elementText: Codable{
let id: Int
let name: String
let text: String
}
let element_texts: [elementText]
}
这是json端点返回的内容：

我正在处理的大多数示例，教程和阅读材料都具有一个json响应，该响应在最顶部具有一个名称（在这种情况下，它可能是项目），但这直接用于嵌套。
所以我的问题是，我上面的类是否正确设置了格式，或者因为它开始嵌套在它的模式中，所以我需要做一些更改吗？
