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 app is…


One of the key facts of the mobile revolution is that we always have a computer that constantly uses GPS in our pocket, to which we can ask anything regarding everything around us.

As we can see by searching the App Store, forecasting weather is a common problem that apps try to solve, often using stunning designs but sometimes using a basic design with a lot a features. This confuses the user.

If we look carefully at the nicest, and most famous, weather apps, we realize that the structures are really similar, and this is the kind of app we want to build.

Although a few apps allow you to check the weather of several cities at a time, for simplicity, we'll implement an app that shows only the weather of your current city.

That said, the aim of the app is:

  • To show the current weather for the current location

  • To show the forecast for the upcoming hours and days

To make the app more appealing, we'll add a nice photo of the current city as the background. The following screenshot shows the...
