Swift 2 By Example

Overview of this book

Swift is no longer the unripe language it was when launched by Apple at WWDC14, now it’s a powerful and ready-for-production programming language that has empowered most new released apps. Swift is a user-friendly language with a smooth learning curve; it is safe, robust, and really flexible. Swift 2 is more powerful than ever; it introduces new ways to solve old problems, more robust error handling, and a new programming paradigm that favours composition over inheritance. Swift 2 by Example is a fast-paced, practical guide to help you learn how to develop iOS apps using Swift. Through the development of seven different iOS apps and one server app, you’ll find out how to use either the right feature of the language or the right tool to solve a given problem. We begin by introducing you to the latest features of Swift 2, further kick-starting your app development journey by building a guessing game app, followed by a memory game. It doesn’t end there, with a few more apps in store for you: a to-do list, a beautiful weather app, two games: Flappy Swift and Cube Runner, and finally an ecommerce app to top everything off. By the end of the book, you’ll be able to build well-designed apps, effectively use AutoLayout, develop videogames, and build server apps.

The interface of the ASAP Server


In the previous chapter, we implemented the app using a local storage, and now we want to implement a server in Swift to handle the products and the cart.

The actions that we want to handle are as follows:

  • Getting the list of the products

  • Adding a product to the cart

  • Removing a product from the cart

  • Creating and ordering from the cart

Using the REST architectural paradigm, we design our server to handle the following actions:

  • HTTP GET of the /products URL, which returns the JSON of the product in the exact format we used in the previous chapter

  • HTTP POST of the /customer/<useremail>/cart/<productID> URL, which creates a new relationship between the cart of the user and the product

  • HTTP DELETE of the /customer/<useremail>/cart/<productID> URL, which removes the relationship between the cart of the user and the product

  • HTTP POST of the /customer/<useremail>/orders URL, which creates a new order based on the customer's cart and resets...
