json - 将字典解码为可编码结构的数组

Question

我有 JSON 作为字典 [String, Anyobject]：

{
  "AED": "United Arab Emirates Dirham",
  "AFN": "Afghan Afghani",
  "ALL": "Albanian Lek",
}

我需要将其解码为可编码结构货币的数组，例如：

struct Currency: Codable {
  var code: String
  var name: String
}

Currency(code: "AED", name: "United Arab Emirates Dirham")

您可以将 json 解码为 Dictionary 并映射到 Array。

let currencies = try? JSONDecoder()
        .decode([String: String].self, from: data)
        .map({ Currency(code: $0.key, name: $0.value) })
