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.

Where do we go from here?


Although our app is almost complete, the possibilities for its expansion are endless.

Starting from this source, you can do the following:

  • Make it more robust in handling error situations. Currently, if anything goes wrong, nothing happens on the user's side because the app just logs the error. A good strategy would be to present a warning somewhere and provide a chance to the user to retry the operation.

  • The app works well if the user allows the use of GPS, but it will stop working if the user denies it. How about adding a functionality to view the weather for more cities than one, swiping horizontally to view a new city?

  • In the app, the background is chosen using only coordinates, but because the images in that group are tagged with the weather, it would be nice to show an image that matches the weather and, maybe, with the correct time of the day or night.

  • A straightforward but really useful feature would be to add the pull-to-refresh functionality to request the...
