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.

Vapor Models


Before we move on to the topic of controllers, we will go back to our ShoppingList Vapor application and create two Vapor Models that will be saved in the database using Fluent. These two Models are the ShoppingList Model and the Item Model. Vapor's Model is an extension on top of Fluent's Entity protocol that conveniently implements certain methods in the protocol so we do not have to write the implementation of these methods for every Model we write. Let's see how we can create these two Models using Vapor's Model protocol.

The Shopping List Model

To create a Shopping List Model, all we need to do is inherit our class from the Model protocol, add a few methods that will be used to create an instance of that type using data from the database, and save the state of an instance into the database. Let's perform the following steps to create our first Shopping List Model in Vapor:

  1. Delete the Post.swift Model file included as part of our template project inside the Models folder. Also...
