如何在SwiftUI中显示来自API的JSON数据？

import SwiftUI

struct ContentView: View {
    @State private var data: [User] = []
    
    var body: some View {
        List(data, id: \.id) { user in
            VStack(alignment: .leading) {
                Text(user.name)
                    .font(.headline)
                Text(user.email)
                    .font(.subheadline)
            }
        }
        .onAppear {
            fetchData()
        }
    }
    
    func fetchData() {
        guard let url = URL(string: "https://api.example.com/users") else {
            return
        }
        
        URLSession.shared.dataTask(with: url) { (data, response, error) in
            if let data = data {
                do {
                    let users = try JSONDecoder().decode([User].self, from: data)
                    DispatchQueue.main.async {
                        self.data = users
                    }
                } catch {
                    print("Error decoding JSON: \(error)")
                }
            }
        }.resume()
    }
}

struct User: Codable, Identifiable {
    let id: Int
    let name: String
    let email: String
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
