如何从具有多个数组和括号的大型 JSON 响应中获取值？

Question

我有一个 JSON 响应（超过 500 行），里面有几个数组和括号。基本上是过度嵌套的响应。

我正在使用 Alamofire 进行抓取，我得到一个 JSON数据作为响应。但我不知道如何从响应中获取值并将其打印在自定义单元格上。

我正在使用 Alamofire 5 来获得 JSON 响应。

如果这听起来太新手请原谅，我是 iOS 开发的新手。

JSON 是一种非常简单且易于阅读的格式。只有两种不同的集合类型和四种值类型。

{} 是一个字典，下标为 key
[] 是一个数组，下标为索引（从零开始）

双引号中的所有内容都是 String，甚至 "123" 和 "false"
false 和 true 是 Bool
数值为Double，不带小数位Int
<null> 是 NSNull
