如何让SwiftUI中的水平ScrollView在所包含的文本更新时自动滚动以结束

import SwiftUI

struct ContentView: View {
    @State private var text: String = ""
    
    var body: some View {
        VStack {
            ScrollView(.horizontal) {
                ScrollViewReader { scrollViewProxy in
                    GeometryReader { geometry in
                        Text(text)
                            .onChange(of: text) { newValue in
                                withAnimation {
                                    scrollViewProxy.scrollTo(text.count - 1, anchor: .trailing)
                                }
                            }
                            .frame(width: geometry.size.width)
                    }
                }
            }
            
            TextField("输入文本", text: $text)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()
        }
    }
}

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