SwiftUI -如何在ScrollView中显示倒计时？

import SwiftUI

struct ContentView: View {
    @State private var remainingSeconds = 60
    let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()
    
    var body: some View {
        ScrollView {
            VStack {
                Text("Remaining Time:")
                    .font(.headline)
                    .padding()
                
                Text("\(remainingSeconds)")
                    .font(.largeTitle)
                    .padding()
                    .onReceive(timer) { _ in
                        if remainingSeconds > 0 {
                            remainingSeconds -= 1
                        }
                    }
            }
        }
    }
}

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