大家，如果字段之一未知，如何序列化json结构？

我的 json 是：

 {"brands":{"any":false,"19":{"is_all":false,"values":[185,182,178],"include":true},"23":{"is_all":false,"values":[198,199,201],"include":true}},"price":[2000,10000],"year":[1990,2018],"fuel_type":[1,2],"engine_capacity":[\"1.8\",\"4.8\"],"color":[1,2,3],"gearbox_id":[2],"is_georgia":false}

但：

"19":{"is_all":false,"values":[185,182,178],"include":true}

"23":{"is_all":false,"values":[198,199,201],"include":true}

19 和 23 - 是字符串未知值，由 API 生成。

所以我的结构是：

    struct auto_order_model: Decodable {
        var brands: brand_details             <---- this is problem
        let price: [Int]
        let year: [Int]
        let fuel_type: [Int]
        let engine_capacity: [String]
        let color: [Int]
        let gearbox_id: [Int]
        let is_georgia: Bool
    }
    struct brand_details: Decodable {
        var any: Bool
        var brand_num: [models]?
    }
    struct models: Decodable {
        var is_all: Bool
        var values: [Int]
        var include: Bool
    }

我像这样解码这个json：

    do {
        let data = …
