Swift UI嵌套数组

Question

我会努力凝结。我正在解析包含数组中的数组的JSON。我无法弄清楚如何在嵌套数组中获取单个值

模型

struct WeatherForcastResponse: Codable {
    let forcasts: [WeatherForcast]
    
    private enum CodingKeys: String, CodingKey {
        case forcasts = "list"
    }
}

struct WeatherForcast: Codable {
    let weatherDate: Double
    let sunrise: Double
    let sunset: Double
    let weatherTemp: WeatherTemp
    let weatherInfo: [WeatherTempInfo]
    
    private enum CodingKeys: String, CodingKey {
        case weatherDate = "dt"
        case sunrise = "sunrise"
        case sunset = "sunset"
        case weatherTemp = "temp"
        case weatherInfo = "weather"
    }
}

// MARK: - DAILY 7 DAY
                ScrollView(.horizontal, showsIndicators: false) {
                    HStack(spacing: 20) {
                        ForEach(weatherListForcastVM.forcasts, id: \.id) { forcast in
                            VStack {
                                ScrollView(.vertical, showsIndicators: false) {
                                    VStack {
                                        Text("\(DateExtensions.shared.convertDate(type: "Short", timezone: passedWeatherDetails.timeZone, passedDate: forcast.weatherDate))")
                                            .bold()
                                        //
                                        //Text(weatherListForcastVM.weatherSkyInfo)

在我的视图模型中，我可以列出所有信息，但是如何在嵌套数组中生成特定值以与索引或父数组相对应？

class WeatherListForcastViewModel: ObservableObject {
    @Published var forcasts = [WeatherForcastViewModel]()
    @Published var weatherTempInfo = [WeatherTempInfo]()
    var weatherSkyInfo = ""
    private var weatherDescriptionInfo = ""
    private var weatherIconInfo = ""
    let jsonService = JSONService()
    
    func getForcastByCityId(cityId: Int) {
        jsonService.getCityWeatherById(cityId: cityId) { result in
            switch result {
            case .success(let details):
                if let details = details {
                    DispatchQueue.main.async {
                        self.forcasts = details.map(WeatherForcastViewModel.init)
                        self.getWeatherItems()
                        
                    }
                }
            case .failure(let error):
                print(error.localizedDescription)
                DispatchQueue.main.async {
                    print(error.localizedDescription)
                }
            }
        }
    }
    
    func getWeatherItems() {
        forcasts.forEach { (item) in
            item.weatherTempInfo.forEach { (x) in
                print("Forcast Description: \(x.sky)")
                weatherSkyInfo = x.sky
            }
        }
    }
