How to make a RESTful app with Siesta

Handling the Navigation to RestaurantDetailsViewController

Finally, you may have noticed that the app doesn’t yet navigate to a screen that shows the details of a restaurant. To do so, open RestaurantListViewController.swift and locate the following extension:

extension RestaurantListViewController: UITableViewDelegate {

Next, add the following delegate method inside of the extension:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
  guard indexPath.row <= restaurants.count else {
    return
  }
  
  let detailsViewController = UIStoryboard(name: "Main", bundle: nil)
    .instantiateViewController(withIdentifier: "RestaurantDetailsViewController") 
      as! RestaurantDetailsViewController
  detailsViewController.restaurantId = restaurants[indexPath.row].id
  navigationController?.pushViewController(detailsViewController, animated: true)
  tableView.deselectRow(at: indexPath, animated: true)
}

Here you simply set up the details view controller, pass in restaurantId for the selected restaurant, and push it on the navigation stack.

Build and run the app. You can now tap on a restaurant that's listed. Tada!

If you swipe back and tap on the same restaurant, you'll see the restaurant details load instantly. This is another example of Siesta's local caching behavior delivering a great user experience:

That’s it! You've built a restaurant search app using Yelp's API and the Siesta framework.
