如何显示一张图片一秒钟？SWIFTUI

import SwiftUI

struct ContentView: View {
    @State private var imageName = "your_image_name"

    var body: some View {
        VStack {
            Image(imageName)
                .resizable()
                .aspectRatio(contentMode: .fit)
        }
        .onAppear {
            // 使用定时器更新图片名称
            Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { timer in
                // 在此处更新图片名称，可以根据自己的需求实现不同的图片切换逻辑
                self.imageName = "your_new_image_name"
            }
        }
    }
}

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