Hands-On Full-Stack Development with Swift

Overview of this book

Making Swift an open-source language enabled it to share code between a native app and a server. Building a scalable and secure server backend opens up new possibilities, such as building an entire application written in one language—Swift. This book gives you a detailed walk-through of tasks such as developing a native shopping list app with Swift and creating a full-stack backend using Vapor (which serves as an API server for the mobile app). You'll also discover how to build a web server to support dynamic web pages in browsers, thereby creating a rich application experience. You’ll begin by planning and then building a native iOS app using Swift. Then, you'll get to grips with building web pages and creating web views of your native app using Vapor. To put things into perspective, you'll learn how to build an entire full-stack web application and an API server for your native mobile app, followed by learning how to deploy the app to the cloud, and add registration and authentication to it. Once you get acquainted with creating applications, you'll build a tvOS version of the shopping list app and explore how easy is it to create an app for a different platform with maximum code shareability. Towards the end, you’ll also learn how to create an entire app for different platforms in Swift, thus enhancing your productivity.

Adding a Shopping List Item


If you have successfully implemented the create and delete functionality for an item in the Shopping List, then good job! If not, we will walk through how you can do so. It is very similar to how we implemented it on the Shopping List. To implement the functionality for adding items to a Shopping List, we need to follow these steps:

  1. Open the Item.swift file inside the iOS project and add a new instance variable to store the shoppingListId. This variable will be passed to the API server along with the name and the isChecked state of the item when creating it so that it can associate this item with the shopping list it is being added to:
var shoppingListId: String?
  1. Add the data commuted property, similar to the one we added in the ShoppingList class, which will convert our object into JSON data that will be passed to our API server. In this case, we will use JSONEncoder instead of JSONSerializer. The reason why we did not convert ShoppingList to JSON data using this...
