Hands-On Full-Stack Development with Swift

By: Ankur Patel

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


To add a Shopping List to our app is as simple making a POST request to the /shopping_lists endpoint with the JSON representation of our Shopping List Model that we want to create. We need to make this request to our Vapor API server and wait for a success response that contains the newly created shopping list object in JSON format. We will then convert it to a ShoppingList model and call the onCompletion handler function that is passed so that the ShoppingListTableViewController can add this new shopping list in its array of lists and tell the Table View to reload with this new Shopping List that is saved on the server.

To implement the add functionality that persists the new Shopping List in the database via our API, we need to follow these steps:

  1. Open the ShoppingList.swift file in the iOS project and add a new computed property called data. This property will return an optional data type and it will return data in JSON format. We will use JSONSerializer to convert...
