SwiftUI |使用ScrollViewReader为scrollTo()自定义动画？

import SwiftUI

struct ContentView: View {
    @State private var scrollToID: Int? = nil
    
    var body: some View {
        VStack {
            Button("Scroll to Item 5") {
                scrollToID = 5
            }
            
            ScrollView {
                ScrollViewReader { proxy in
                    VStack {
                        ForEach(0..<10) { i in
                            Text("Item \(i)")
                                .frame(width: 200, height: 50)
                                .id(i)
                        }
                    }
                    .onChange(of: scrollToID) { id in
                        withAnimation {
                            proxy.scrollTo(id, anchor: .top)
                        }
                    }
                }
            }
        }
    }
}

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