为什么博客园的语言没有swift啊！

import SwiftUI

struct MenuItem: Identifiable {
    var id = UUID()
    var function: String
    var description: String
    var imageName: String
}

let menuItems = [
    MenuItem(function: "a", description: "a", imageName: "flower"),
    MenuItem(function: "a", description: "a", imageName: "a"),
    MenuItem(function: "a", description: "a", imageName: "a"),
    MenuItem(function: "a", description: "a", imageName: "a"),
    MenuItem(function: "a", description: "a", imageName: "a")
]

struct ContentView: View {
    var body: some View {
        NavigationView{
            List(menuItems) { menuItem in
                NavigationLink(destination:
                                Image("flower")){
                    Image(systemName: "photo")
                    VStack {
                        Text(menuItem.function)
                        Text(menuItem.description)
                    }
                    .font(.largeTitle)
                }
            }
            .navigationBarTitle(Text("Tang"))
            
        }
    }
}

List遍历数组一开始不成功，发现是MenuItem结构没有实现Identifiable。还有一个小问题，在iPhone上导航栏正好占满屏幕，所以启动界面就是导航栏。而iPad是导航栏的返回界面。
