如何在SwiftUI中设置嵌入在ForEach中的HStack的相对宽度？

struct ContentView: View {
    let data = ["Item 1", "Item 2", "Item 3", "Item 4", "Item 5"]
    
    var body: some View {
        GeometryReader { geometry in
            VStack {
                ForEach(data, id: \.self) { item in
                    GeometryReader { itemGeometry in
                        HStack {
                            Text(item)
                                .frame(width: itemGeometry.size.width * 0.5, height: 50)
                                .background(Color.blue)
                            
                            Spacer()
                        }
                        .frame(width: geometry.size.width, height: 50)
                    }
                }
            }
        }
    }
}
