json文件的正确语法是什么

Question

我希望用json文件中的数据填充各种集合视图和表视图。但是，我不知道如何编写JSON文件。

这是我想要填充的数据：

• 2个扇区："；数据"；以及"；开发者">
• 每个扇区包含多个项目：

对于"；数据"：

• "数据科学家">
• "商业智能分析员(BIA(">
• "数据库开发人员">
• "数据库管理员">
• "数据工程师">
• "Data Analytics Manager">
• "数据安全管理员">

对于"；显影剂"：

• "APL">
• "BASIC">
• "Eiffel">
• "Frink">
• "Lisp">
• "Pascal">
• "Python">
• "Ruby">
• "S-Lang">

我需要如何组织数据以便以后检索它们？

Answer 1

要将JSON翻译成部分，我建议使用数组

[
{"title":"data",
"items":["Data Scientist","Business Intelligence Analyst (BIA)","Database Developer","Database Administrator","Data Engineer","Data Analytics Manager","Data Security Administrator"]
},
{"title":"developer",
"items":["APL","BASIC","Eiffel","Frink","Lisp","Pascal","Python","Ruby","S-Lang"]
}
]

并将其解码为

struct Section : Decodable {
let title : String
let items : [String]
}

它是最适合表/集合视图数据源的结构

Answer 2

JSON是一种非常稳定的正向格式-字符串用双引号表示，数组用方括号表示，字典用花括号表示：

{
"data" : [
"Data Scientist",
"Business Intelligence Analyst (BIA)",
"Database Developer",
"Database Administrator",
"Data Engineer",
"Data Analytics Manager",
"Data Security Administrator"
],
"developer": [
"APL",
"BASIC",
"Eiffel",
"Frink",
"Lisp",
"Pascal",
"Python",
"Ruby",
"S-Lang"
]
}
