This training page let you understand the Vstack purpose but if you look at my own way of doing it I Made it disappear ??? is this a new release from Swift ?

import SwiftUI

struct ContentView: View {
    var body: some View {
        Text("Why not try…")
               .font(.largeTitle.bold())
        Spacer()
        Circle()
            .fill(.blue)
            .padding()
            .overlay(
            Image(systemName: "figure.archery")
                .font(.system(size: 144))
                .foregroundColor(.white)
        )
        Text("Archery!")
            .font(.title)
        
        Spacer()
    }
}

#Preview {
