从 Swift 中的两个数组生成字典数组

Question

我有两本词典：

name = ["A","B","C","D","E"]
number = ["1","2","3","4","5"]

如何使用内置函数生成以下内容？

[
    {name : "A", number: "1"},
    {name : "B", number: "2"},
    {name : "C", number: "3"},
    {name : "D", number: "4"},
    {name : "E", number: "5"}
]

Answer 1

您显示的期望结果不是单个字典，而是字典数组，即 [[String: String]]。

您可以像这样转换两个数组：

name = ["A","B","C","D","E"]
number = ["1","2","3","4","5"]

let result = zip(name, number).map { ["name": [=10=], "number": ] }

但是，我建议您创建一个 struct/class 来存储这些 name/number 对，而不是使用字典数组：

struct Foo { // give this an appropriate name!
    let name: string
    let number: String
}

let result = zip(name, number).map { Foo(name: [=11=], number; ) }
