使用动态结构在SwiftUI中加载json

struct User: Codable {
    let name: String
    let age: Int
}

import SwiftUI

struct ContentView: View {
    @State private var users: [User] = []

    var body: some View {
        List(users, id: \.name) { user in
            Text(user.name)
            Text("\(user.age)")
        }
        .onAppear {
            loadData()
        }
    }

    func loadData() {
        guard let url = Bundle.main.url(forResource: "data", withExtension: "json") else {
            return
        }

        do {
            let data = try Data(contentsOf: url)
            let decoder = JSONDecoder()
            users = try decoder.decode([User].self, from: data)
        } catch {
            print("Error loading data: \(error.localizedDescription)")
        }
    }
}

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}
