Completing the Restaurant Detail screen

You now have a SwiftUI map view displaying a map. Now, you’ll create a new SwiftUI view to represent the Restaurant Detail screen and add the map view to it. Do the following steps:

1. Choose File | New | File to open the template selector.
2. iOS should already be selected. In the User Interface section, click SwiftUI View and click Next.
3. Name the new file RestaurantDetail and click Create. The RestaurantDetail file appears in the Project navigator.
4. Declare and define the RestaurantDetail and RestaurantDetail_Previews structures as shown:

   import SwiftUI
   struct RestaurantDetail: View {  
      var selectedRestaurant: RestaurantItem
      var body: some View {
         VStack {
            MapView(lat: selectedRestaurant.lat, 
            long: selectedRestaurant.long)
            .frame(height: 250)
            VStack(alignment: .leading) {
               Text(selectedRestaurant.title)
                  .font(.largeTitle)
          ...
