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.

Testing the Vapor application


Testing a Vapor application is same as testing a Swift package. In Chapter 1Getting Started with Server Swift, you got a primer on Swift packages, and you wrote your first test for that package. Writing test is very similar, and our Vapor application comes with some dummy tests. If we look at the Test/AppTests folder, we will see the following two files:

  • RouteTests.swift
  • Utilities.swift

RouteTests.swift contains two tests that test the routes of our Vapor application and ensure that the output we are getting from our Vapor app is what we expect to get. For Swift to run our test, we will need to start up the server, and, for that, we will need to define some helper extension methods on the Droplet class, and those are defined in the Utilities.swift file, where it creates a Droplet configured with the test environment, as follows:

static func testable() throws -> Droplet {
  let config = try Config(arguments: ["vapor", "--env=test"])
  try config.setup()
  let...
