SwiftUI:如何使用ForEach遍历包含各种代码的各种结构？

struct ContentView: View {
    let codes = ["A", "B", "C", "D"]
    
    var body: some View {
        VStack {
            ForEach(codes, id: \.self) { code in
                switch code {
                case "A":
                    Text("This is code A")
                case "B":
                    Button(action: {
                        // 按钮点击事件
                    }) {
                        Text("This is code B")
                    }
                case "C":
                    TextField("Enter code C", text: .constant(""))
                case "D":
                    Image(systemName: "star.fill")
                        .foregroundColor(.yellow)
                default:
                    EmptyView()
                }
            }
        }
    }
}
