I need to create a list view with item like a square on a scrollview.

But I need to make the scroll only work to one item to another.

I could see the article allowing to set up this system on a HStack but I can't adapt it on a VStack

This article : https://levelup.gitconnected.com/snap-to-item-scrolling-debccdcbb22f

If someone has an idea to help me in this research?

I join an example of scrollview with the square :

struct ScrollingSnapped: View {

    var colors: [Color] = [.blue, .green, .red, .orange, .gray, .brown, .yellow, .purple]

    var body: some View {
        ScrollView {
            VStack(alignment: .trailing, spacing: 30) {
                ForEach(0..<colors.count) { index in
                    colors[index]
                        .frame(width: 250, height: 250, alignment: .center)
                        .cornerRadius(10)
                }
            }
        }
    }
}

struct ScrollingSnapped_Previews: PreviewProvider {
    static var previews: some View {
        ScrollingSnapped()
    }
}

I tried to work with a ScrollViewReader that allows to scrollTo. It works when clicking on a button but I can't get it to work when scrolling :

import SwiftUI

struct ScrollingSnapped: View {

    var colors: [Color] = [.blue, .green, .red, .orange, .gray, .brown, .yellow, .purple]

    var body: some View {
        ScrollViewReader { proxy in
            ScrollView {
                Button {
                    proxy.scrollTo(4, anchor: .top)
                } label: {
                    Text("Scroll to square 5")
                }

                VStack(alignment: .trailing, spacing: 30) {
                    ForEach(0..<colors.count) { index in
                        colors[index]
                            .frame(width: 250, height: 250, alignment: .center)
                            .cornerRadius(10)
                            .id(index)
                    }
                }
            }
        }
    }
}

struct ScrollingSnapped_Previews: PreviewProvider {
    static var previews: some View {
        ScrollingSnapped()
    }
}
