我们如何在SwiftUI中延迟加载数据到表单/列表？

import SwiftUI

struct ContentView: View {
    @State private var data: [String] = []
    
    var body: some View {
        List(data, id: \.self) { item in
            Text(item)
        }
        .onAppear {
            // 在视图出现时加载数据
            loadData()
        }
    }
    
    func loadData() {
        // 模拟异步加载数据
        DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
            data = ["Item 1", "Item 2", "Item 3"]
        }
    }
}

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