Swift：如何正确解析嵌套数组对象并在UI中使用它们

很抱歉，如果以前已经回答了这个问题，但是我找不到能真正回答我问题的东西：所以我已经尝试了好几天了，但似乎无法使它正常工作。我正在尝试解析JSON文件中的嵌套数组以预览行中的项目。我不确定是否是因为我没有正确解码JSON文件或什么，但是任何帮助都会很棒！

MonthData的代码：// MonthData.swift //

struct MonthData: Codable {
    var month: [MonthlyData]
}

struct MonthlyData: Codable {
    var monthName: String
    var dayInfo: [DailyData]
}

struct DailyData: Codable {
    var id: Int
    var whatILove: String
    let imageName: String
    var date: String
    var paragraph: String
}

JSON文件（简体）：// 2020Test.json //

[
    "month": [
        {
            "monthName": "July",
            "dayInfo": [
                {
                    "whatILove": "I Love Your Smile",
                    "imageName": "image1",
                    "date": "07/22/20",
                    "paragraph": "...",
                    "id": 1
                },
                {
                    "whatILove": "I Love Your Laugh",
                    "imageName": "image2",
                    "date": "07/23/20",
                    "paragraph": "...",
                    "id": 2
                },
            ]
         },
         {
            "monthName": "August",
            "dayInfo": [
                {
                    "whatILove": "I Love Your Music",
                    "imageName": "image4",
                    "date": "08/01/20",
                    "paragraph": "...",
                    "id": 11
                },
                {
                    "whatILove": "I Love Your Kiss",
                    "imageName": "image6",
                    "date": "08/02/20",
                    "paragraph": "...",
                    "id": 12
                },
             ]
         }
     ]
]

我一直在想这可能是我对其进行解码的方式，但是我也不确定-我只是使用了可以从Apple SwiftUI课程获得的Json文件。

Json解码器文件：// jsonDecode.swift //

let monthData: [MonthData] = load("2020Test.json")

func load<T: Decodable>(_ filename: String) -> T {
    let data: Data
    
    guard let file = Bundle.main.url(forResource: filename, withExtension: nil)
        else {
            fatalError("Couldn't find \(filename) in main bundle.")
    }
    
    do {
        data = try Data(contentsOf: file)
    } catch {
        fatalError("Couldn't load \(filename) from main bundle:\n\(error)")
    }
    
    do {
        let decoder = JSONDecoder()
        return try decoder.decode(T.self, from: data)
    } catch {
        fatalError("Couldn't parse \(filename) as \(T.self):\n\(error)")
    }
}

最后，这是我要使用JSON数据的文件：// DayRow.swift //

    struct DayRow: View {
    
    var day: DayData
    
    var body: some View {
        HStack {
            Image(day.imageName)
                .resizable()
                .aspectRatio(contentMode: .fill)
                .frame(width: 50, height: 50, alignment: .top)
                .clipShape(Circle())
            
            VStack(alignment: .leading) {
                Text("\(day.date) - Day \(day.id)")
                    .font(.footnote)
                    .fontWeight(.light)
                Text(day.whatILove)
                    .fontWeight(.semibold)
            }
        }
    }
}

如果我的JsonDecoder运行正常，那么我不确定如何从嵌套数组中实际获取数据。我需要在DayRow.swift中调用其他变量吗？预先谢谢你！
