Wrong type description on the step 7 "Add markers to the map" on "Add a map to your iOS app with SwiftUI (Swift)" tutorial.

[Suprafen]

Issue description

In the example bellow CitiesList described as a class in the message before code snippet. Which is not correct.

Notice that ContentView uses the markers property to render the list of cities by passing it to the CitiesList class.

struct CitiesList: View {

  @Binding var markers: [GMSMarker]

  var body: some View {
    GeometryReader { geometry in
      VStack(spacing: 0) {
        // ...
        // List of Cities
        List {
          ForEach(0..<self.markers.count) { id in
            let marker = self.markers[id]
            Button(action: {
              buttonAction(marker)
            }) {
              Text(marker.title ?? "")
            }
          }
        }.frame(maxWidth: .infinity)
      }
    }
  }
}

Suggested solutions

1. Substitute the word class with struct as shown bellow:

Notice that ContentView uses the markers property to render the list of cities by passing it to the CitiesList struct.

2. Or just leave it as suggested in this example:

Notice that ContentView uses the markers property to render the list of cities by passing it to the CitiesList.
