Swift、JSON 型号

Question

我有一个关于构建 JSON 模型的问题，即我应该声明每天不同的日期 - 在这种情况下：“2020-11-19”，如下所示。

这是当天的回复。

{
  "dates": {
    "2020-11-19": {
      "countries": {
        "Poland": {

我应该如何构建一个模型，以便这个属性每天都在变化？（当然，这个日期需要有一个正确的格式“yyyy-MM-dd”）

Answer 1

我可能会这样做：

var dates: [String: YourModel]

如果它可能在该字段中有多个日期..否则，我可能会做一个自定义对象来覆盖 init(from decoder: 并解析出该信息
