SwiftUI列表在任何视图更改时重置滚动

import SwiftUI

struct ContentView: View {
    @State private var items = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

    var body: some View {
        GeometryReader { geometry in
            ScrollViewReader { scrollViewProxy in
                VStack {
                    Button("Add Item") {
                        // 添加项目
                        items.append(items.count + 1)
                        scrollToTop(scrollViewProxy: scrollViewProxy)
                    }
                    
                    Button("Remove Item") {
                        // 删除项目
                        items.removeLast()
                    }
                    
                    List {
                        ForEach(items, id: \.self) { item in
                            Text("Item \(item)")
                                .frame(height: 50)
                        }
                    }
                    .id(items.count) // 用于更新列表视图
                    .onChange(of: items.count) { _ in
                        scrollToTop(scrollViewProxy: scrollViewProxy)

                }
            }
        }

    func scrollToTop(scrollViewProxy: ScrollViewProxy) {

        }
    }
