How can I detect the View overflowing the screen?

Question

Question: How can I detect the View overflowing the screen? For example, I want to write +1(+n) for the view that goes out of the screen.

TagList:

struct TagListView: View {
    var tags = ["iPhone X", "iPhone 11", "iPhone 12", "iPhone 12 Pro Max"]
    var body: some View {
        VStack {
            HStack {
                ForEach(tags.indices, id: \.self) { index in
                    GeometryReader { geo in
                        TagCell(tag: tags[index])
                            .onAppear {
                                print("\(geo.frame(in: .global).maxX)")
                            }
                    }
                }
            }
        }
    }
}

TagCell:

struct TagCell: View {
    var tag: String
    var body: some View {
        Text(tag)
            .fixedSize()
            .foregroundColor(.yellow)
            .padding(8)
            .background(Color.yellow.opacity(0.15))
            .cornerRadius(15)
    }
}
