如何在swiftUI中使用抓取的数据

import SwiftUI

struct ContentView: View {
    @State private var data: [Item] = []

    var body: some View {
        VStack {
            Button("Fetch Data") {
                fetchData()
            }
            
            List(data, id: \.id) { item in
                Text(item.name)
            }
        }
    }
    
    func fetchData() {
        guard let url = URL(string: "https://api.example.com/data") else {
            return
        }
        
        URLSession.shared.dataTask(with: url) { (data, response, error) in
            if let data = data {
                do {
                    let decoder = JSONDecoder()
                    let items = try decoder.decode([Item].self, from: data)
                    DispatchQueue.main.async {
                        self.data = items
                    }
                } catch {
                    print("Error decoding data: \(error)")
                }
            }
        }.resume()
    }
}

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

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