Question

我在解析从Oxford Dictionaries检索到的一些JSON数据到我的应用程序时遇到了问题。

我正在将JSON响应打印到我的控制台，确认我已成功获取所需的数据。

验证正在检索JSON数据：

Verification that JSON data is being retrieved

当我收到JSON数据时，最初有两个主要文件夹。＆＃34;结果＆＃34;，其中包含我需要的信息：单词定义和其他信息

和＆＃34;元数据＆＃34;。

我从牛津词典回来的JSON格式：

JSON format that I am getting back from Oxford Dictionary

我能够解析＆＃34;元数据中包含的信息＆＃34;文件夹，并将其打印到控制台进行确认。

验证我能够解析和打印元数据：

Verification that I am able to parse and print the metadata

但是，我似乎无法解析“结果”中包含的任何数据。文件夹，这是我真正需要的。定义，语言，单词ID等。我在这做错了什么？

解析问题的示例＆＃34;结果＆＃34;数据 Example of issue with parsing "results" data

另一个错误尝试解析结果的例子＆＃39;

Answer 1

检索这样的结果：

let results = json["results"][0]["id"]

id键位于字典中，该字典位于结果数组的零索引处。

只能解析一些JSON数据，语法问题？
