Now open RestaurantDetailViewController.swift and update the total number of cells:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return 3 }

Also, update the tableView(_:cellForRowAt:) method like this:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { switch indexPath.row { case 0: let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: RestaurantDetailTextCell.self), for: indexPath) as! RestaurantDetailTextCell cell.descriptionLabel.text = restaurant.description return cell case 1: let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: RestaurantDetailTwoColumnCell.self), for: indexPath) as! RestaurantDetailTwoColumnCell cell.column1TitleLabel.text = "Address" cell.column1TextLabel.text = restaurant.location cell.column2TitleLabel.text = "Phone" cell.column2TextLabel.text = restaurant.phone return cell case 2: let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: RestaurantDetailMapCell.self), for: indexPath) as! RestaurantDetailMapCell return cell default: fatalError("Failed to instantiate the table view cell for detail view controller") } }

In the code above, we just added a new case to handle the map cell. Let's hit the Run button to have a quick test. When you select a restaurant to navigate to the detail view, it shows a map. This is the power of MapKit. Without writing a line of code for the map view, you already embed a map within your app. Right now, it only displays a default map based on your current location. But it's really cool, right?
