Swift解码json，密钥以数字开头

我有一个json，格式如下：

let json = """
{
    "stuff": {
        "1": "one",
        "2": "two",
        "4": "four"
    }
}

问题是我怎样才能使我的

struct Stuff: Codable, Equatable {
    let 1: String
    let 2: String
    let 4: String
}

编译和工作

我经常用下面的代码来称呼它，它对任何事情都很好，但如果让name以number开头，它显然无法编译

let obj = try? JSONDecoder().decode(T.self, from: data)

你不能。变量不得以数字字符开头。不变的规则

但是您可以使用

CodingKeys

struct Stuff: Codable, Equatable {
    let one, two, four: String

    private enum CodingKeys : String, CodingKey { case one = "1",  two = "2", four = "4"}
}

你不能。JSON标准规定对象键必须是字符串

object = begin-object [ member *( value-separator member ) ]
           end-object

member = string name-separator value

变量名也可以以下划线开头（挑剔）@Sulthan我指定了规则是的，我明白了。但我无法更改外部API:D
