Итак, у меня есть некоторые данные JSON, которые я извлекаю из API с помощью alamofire. Когда данные возвращаются, структура выглядит так
{
"sneakers" : {
"brands" : {
"Adidas" : [ {
"brand" : "adidas",
"category" : "lifestyle",
"colorway" : "Cream White/Cream White/Core White",
"description" : "First released on April 29, 2017, the Yeezy Boost 350 V2 ‘Cream White’ combines a cream Primeknit upper with tonal cream SPLY 350 branding, and a translucent white midsole housing full-length Boost. Released again in October 2018, this retro helped fulfill Kanye West’s oft-repeated ‘YEEZYs for everyone’ Twitter mantra, as adidas organized the biggest drop in Yeezy history by promising pre-sale to anyone who signed up on the website. Similar to the first release, the ‘Triple White’ 2018 model features a Primeknit upper, a Boost midsole and custom adidas and Yeezy co-branding on the insole.",
"designer" : "Kanye West",
"imagesrc" : "https://image.goat.com/crop/1250/attachments/product_template_additional_pictures/images/014/822/695/original/116662_03.jpg.jpeg",
"maincolor" : "White",
"name" : "Yeezy Boost 350 V2 'Cream White / Triple White'",
"nickname" : "Cream White / Triple White",
"price" : "Buy New - $220",
"productlink" : "$190YEEZY BOOST 350 V2 'CREAM WHITE / TRIPLE WHITE'",
"productlinkhref" : "https://www.goat.com/sneakers/yeezy-boost-350-v2-cream-white-cp9366",
"releasedate" : "2017-04-29",
"silhouette" : "Yeezy Boost 350",

"webscraperorder" : "1554084922-147",
"webscraperstarturl" : "https://www.goat.com/sneakers"
}

Где потенциально может быть больше брендов (Nike, Air Jordan), под которыми больше кроссовок. Используя протокол Swift Decodable, я смог правильно разобрать данные JSON на объекты, которые легко читаются любым пользователем. Этот код можно увидеть ниже.
import Foundation
import RealmSwift
import Realm
struct Sneaker: Decodable {
var sneakers : Sneakers
}
struct Sneakers: Decodable {
let brands: Shoe
}
struct Shoe: Decodable {
let adidas: [SneakerInfo]
let nike: [SneakerInfo]
let airjordan: [SneakerInfo]
let vans: [SneakerInfo]
enum CodingKeys: String, CodingKey {
case adidas = "Adidas"
case nike = "Nike"
case airjordan = "Air Jordan"
case vans = "Vans"
}
}
struct SneakerInfo: Decodable {
let brand, category, colorway, description: String?
let designer: String?
let imagesrc: String?
let maincolor, name, nickname, price: String?
let productlink: String?
let productlinkhref: String?
let releasedate, silhouette, technology, webscraperorder: String?
let webscraperstarturl: String?
enum CodingKeys: String, CodingKey {
case brand, category, colorway, description, designer, imagesrc, maincolor, name, nickname, price, productlink, productlinkhref, releasedate, silhouette, technology,webscraperorder,webscraperstarturl
}
}
В настоящее время я пытаюсь перенести этот же код, чтобы он был готов к использованию с областью и возможностью кодирования, но я продолжаю получать ошибки.
Моя проблема жалуется на мою реализацию и файл inits. Я включу класс ниже. Я застрял на этом весь день.

Основная ошибка
Свойство self.sneaker не инициализируется при вызове super.init
а также
Свойство self.brands не инициализируется при вызове super.init
