我有这个var json : [[String : Any]] = [[:]]包含 JSON 响应如下：

{
"id": "1",
"name": "Apple",
"category_name": "Fruits"
},
{
"id": "2",
"name": "Black shirt",
"category_name": "Fashion"
},
{
"id": "3",
"name": "iPad",
"category_name": "Gadgets"
}

我写了一个枚举：

enum : Int {
        case fruits = 0, fashion, gadgets
    }

var data = [Categories: [[String: Any]]]()

然后我有这个方法来对类别进行排序：

func sortData() {
        data[.fruits] = self.json.filter({ $0["category_name"] == "Fruits" })
        data[.fashion] = self.json.filter({ $0["category_name"] == "Fashion" })
        data[.gadgets] = self.json.filter({ $0["category_name"] == "Gadgets" }) …
