// Anti-pattern: stores an escaping closure on the view.
struct CardView<Content: View>: View {
 let content: () -> Content

 var body: some View {
 VStack(alignment: .leading) {
 content()
 }
 .padding()
 .background(.ultraThinMaterial)
 .clipShape(.rect(cornerRadius: 8))
 }
}

// Preferred: store the built view value; the synthesized init handles calling the builder.
struct CardView<Content: View>: View {
 @ViewBuilder let content: Content

 var body: some View {
 VStack(alignment: .leading) {
 content
 }
 .padding()
 .background(.ultraThinMaterial)
 .clipShape(.rect(cornerRadius: 8))
 }
}
