SwiftUI: Building a list of navigation links using ForEach

Question

How can I build a list of navigation list using ForEach in SwiftUI. I thought of something like below but it doesn't work.

struct ContentView: View {
  
  var menuButtons = ["Profile", "About Us", "Contact Us"]
  
    var body: some View {
        
      ForEach(menuButtons, id:\.self) {menu in
        NavigationView(content: {
          NavigationLink(destination: {
            if menu == "Profile" {
              Profile()
            }
            if menu == "About Us" {
              AboutUs()
            }
          }) { Text(menu) }
        })
      }
    }
}

Move the NavigationView outside the ForEach, otherwise you'll have multiple navigation views.
You also want a VStack that wraps the ForEach, so the navigation links are stacked.
Wrap the if statements inside a Group to group it into a single View, which the destination expects.

struct ContentView: View {
    var menuButtons = ["Profile", "About Us", "Contact Us"]
    
    var body: some View {
        NavigationView { /// 1.
            VStack { /// 2.
                ForEach(menuButtons, id: \.self) { menu in
                    NavigationLink(
                        destination:
                            Group { /// 3.
                                if menu == "Profile" {
                                    Profile()
                                }
                                if menu == "About Us" {
                                    AboutUs()
                                }
                            }
                    ) {
                        Text(menu)
                    }
                }
            }
        }
    }
}

Result:

Home page (ContentView)	After clicking a navigation link
