ScrollView doesn't scroll properly (bounces) in combination with Geometry Reader

Question

I already reviewed the answer here (ScrollView Doesn't Scroll with Geometry Reader as Child) which is I guess pretty similar but I wasn't able to figure it out.

My Goal is to show the images equally sized (quadratic).

Here's my View:


struct MyGeoView: View {
    
    let icons = ["bed.double.fill","tram.fill","tv.music.note.fill","hare.fill", "person", "clock", "plus", "trash", "home", "arrow", "pencil", "scribble", "folder", "folder.circle", "trash.circle", "paperplane"]
    
    var body: some View {
        
        GeometryReader{ geo in
            ScrollView{
                GeometryReader{ geo in
                    LazyVGrid(columns: Array(repeating: GridItem(.flexible()), count: 3), spacing: 3 ){
                        ForEach(icons, id: \.self){ post in
                            Image(systemName: post)
                                .frame(width: geo.size.width/3, height: geo.size.width/3)
                                .background(Color.pink)
                                .foregroundColor(.white)
                        }
                    }
                }
            }
        }
    }
    
}

Unfortunately it's not scrolling properly (bounces) and always goes back to top. Do you have some ideas?

Thanks!

You just need only one GeometryReader, external one.

Here is corrected code. Tested with Xcode 12.1 / iOS 14.1

var body: some View {
    GeometryReader{ geo in
        ScrollView{
            LazyVGrid(columns: Array(repeating: GridItem(.flexible()), count: 3), spacing: 3 ){
                ForEach(icons, id: \.self){ post in
                    Image(systemName: post)
                        .frame(width: geo.size.width/3, height: geo.size.width/3)
                        .background(Color.pink)
                        .foregroundColor(.white)
                }
            }
        }
    }
}
