swift - JSON 的正确类结构被推送到本地 Realm

Question

好吧，基本上我想做的是从我制作的 API 中提取运动鞋数据，该 API 保存有关各种运动鞋的数据。 json 结构看起来像这样。

  sneakers {
        bramds {
             nike
                 nikeshoe1
                 nikeshoe2
                 ......
            jordan
                 jordanshoe1
                 jordanshoe2
                 ......
}
}

我想在 swift 中创建一个继承可解码类的类，以便我可以解析和反序列化 json 并将其传递给 Realm 。我看了这个指南，但我仍然有点卡在建模部分。目前我所拥有的是这样的

import Foundation
import RealmSwift


struct Sneaker: Decodable {
    var brands : [Brands]

}

struct Brands: Decodable {
    var brandName: String
    var shoe: [Shoe]

}

struct Shoe:Decodable {

    var productlink: String
    var productlinkhref: String
    var name: String
    var price: String
    var releasedate: String
    var colorway: String
    var brand: String
    var designer: String
    var technology: String
    var maincolor: String
    var silhouette: String
    var nickname: String
    var category: String
    var imagesrc: String

}

我只是想弄清楚我是否走在正确的轨道上，使这些模型可以根据我的 JSON 结构进行解码。除此之外，将可解码对象推送到 Realm 的正确语法是什么，它会是相同的语法吗？我在下面提供了一个 JSON 示例，欢迎任何帮助

看起来您的方向是正确的，但是您看过 Apple 的示例吗？

https://developer.apple.com/documentation/foundation/archives_and_serialization/using_json_with_custom_types

我发现可下载的 Playground 非常有帮助。

此外，由于您可以设计 JSON，因此您可以自由地将 JSON 镜像为您想要的 Swift 数据结构。所以我会从那开始倒退。
