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.

Routing in Vapor


Routing is a very important feature of any web application. It is the interface through which you can access the application and perform certain actions on it. HTTP is the protocol used in routing. We went through the basics of HTTP in Chapter 1Getting Started with Server Swift, and as you might be aware, HTTP protocol requires a method, a path, a set of headers, and an optional body to make a request to the server. The server then responds back with a message that contains a status code, a set of Response headers, and a message body.

HTTP methods

For most of the web, there are five commonly used HTTP methods, which are as follows:

  • GET
  • POST
  • PATCH
  • PUT
  • DELETE
  • OPTIONS

There are also other methods that are less used and can be passed in the request to a web application. If it is able to handle it, the routing rules will determine who should be handling the request.

Vapor's droplets give us easy-to-use APIs to construct routes for these commonly used HTTP methods. All we need to do is...
