How to create a custom alignment guide Paul Hudson @twostraws May 12th 2022

I tried building this example today and the vertical alignment does nothing. Did Apple change something?

import SwiftUI

extension VerticalAlignment {
    enum MidAccountAndName: AlignmentID {
        static func defaultValue(in d: ViewDimensions) -> CGFloat {
            d[.top]
        }
    }

    static let midAccountAndName = VerticalAlignment(MidAccountAndName.self)
}

struct ContentView3: View {
    var body: some View {
        HStack {
            VStack {
                Text("@twostraws")
                    .alignmentGuide(.midAccountAndName) { d in d[VerticalAlignment.center] }
                Image("kitten").resizable()
                    .frame(width: 64, height: 64)
            }

            VStack {
                Text("Full name:")
                Text("PAUL HUDSON")
                    .alignmentGuide(.midAccountAndName) { d in d[VerticalAlignment.center] }
                    .font(.largeTitle)
            }
        }
        .padding()
    }
}

struct ContentView3_Previews: PreviewProvider {
    static var previews: some View {
        ContentView3()
    }
}

I see what I did wrong. I left off the HStack addition:

HStack(alignment: .midAccountAndName) {
