如何显示文本2秒，然后将其隐藏在SwiftUI中？

@State private var isTextVisible = true

import SwiftUI

struct ContentView: View {
    @State private var isTextVisible = true
    
    var body: some View {
        VStack {
            if isTextVisible {
                Text("Hello, World!")
                    .font(.title)
                    .foregroundColor(.blue)
                    .onAppear {
                        DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
                            isTextVisible = false
                        }
                    }
            }
        }
    }
}
