在 Swift 中解碼復雜的嵌套 JSON 4 很多錯誤

Question

我正在嘗試將 model 這個嵌套的 JSON 轉換為可讀的 object 在 ZAE832E9B5BDA2699DB45F 中遇到很多不必要的 556 問題。 我想將聖經從 JSON 加載到我的應用程序中，這樣我就可以從數據角度使用它。 這是我的代碼：

struct Bible: Codable {
    var book: String
    var chapters: [Chapter]
}
struct Chapter: Codable {
    var chapter: String
    var verses: [Verse]
}
struct Verse: Codable {
    var verse: [String:String]
}

---

import UIKit
class ViewController: UIViewController {
    var bible: Bible?
    var myText: String?

    override func viewDidLoad() {
        super.viewDidLoad()
        let urlString = "https://raw.githubusercontent.com/aruljohn/Bible-kjv/master/Genesis.json"
        if let url = URL(string: urlString){
            if let data = try? Data(contentsOf: url){
               parse(json: data)
            }
        }
    }//end of viewDidLoad

    func parse(json: Data) {
        let decoder = JSONDecoder()
        if let jsonBible = try? decoder.decode(Bible.self, from: json) {
            bible = jsonBible.self
            bible?.book = jsonBible.book
        }
        myText = bible!.book
        print(myText)
    }//end of parse
}

這是 JSON 的小樣本：

{
"book":"Genesis",
"chapters":[
{
"chapter":"1",
"verses":[
{
"1":"In the beginning God created the heaven and the earth."
},
{
"2":"And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters."
},
{
"3":"And God said, Let there be light: and there was light."
},
{
"4":"And God saw the light, that it was good: and God divided the light from the darkness."
},
{
"5":"And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day."
},
{
"6":"And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters."
},
{
"7":"And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so."
},

（原諒可讀性）

首先，我擁有的 model 不會讓我訪問我想要的數據。 目前 Swift 沒有讀取我在結構中的一個字段，即使它就在那里。 它給了我所有類型的錯誤，所以我注釋掉了聖經結構中的章節字段。 我取消注釋它，現在 Swift 就像它不存在一樣，現在我也無法訪問它。

我做錯了什么？

Answer 1

代替

var verses: [Verse]

和

var verses: [[String:String]]

Answer 2

嘗試這個：

import Foundation

// MARK: - Bible
struct Bible: Codable {
    let book: String
    let chapters: [Chapter]
}

// MARK: - Chapter
struct Chapter: Codable {
    let chapter: String
    let verses: [[String: String]]
}

為了解碼 JSON 我使用了這個：

func fetchBible() {
    let urlString = "https://raw.githubusercontent.com/aruljohn/Bible-kjv/master/Genesis.json"
    guard let url = URL(string: urlString) else {
        print("Not url")
        return
    }
    let request = URLRequest(url: url)
    let task = URLSession.shared.dataTask(with: request) { data, response, error in
        guard let data = data, error == nil else {
            print(error!.localizedDescription)
            return
        }
        guard let bible = try? JSONDecoder().decode(Bible.self, from: data) else {
            print("Error decoding JSON")
            return
        }
        DispatchQueue.main.async {
            print(bible)
        }
    }
    task.resume()
}
