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.

Creating the Native App

In the previous chapter, we got a little preview of server-side Swift. Now, we will switch gears, and start working with Swift on a platform that it was originally designed for: Apple's iOS. Swift is currently a very popular language for app development, not only for iOS, but also for tvOS and macOS platforms. In this chapter, we will focus on iOS and build our first iOS app in pure Swift using Xcode. We will be following the model-view-controller architectural pattern popular for building apps in iOS. In the chapter, we will cover the following:

The features of our Shopping List app
Walk through how to create a new app project using Xcode
The structure of an app and its Models, Views, and View Controllers
Learn how to use the storyboard to create and link View Controllers
Wire up the Table View Controllers to show Shopping List Items in our Shopping...
