Learn Swift by Building Applications

Overview of this book

Swift Language is now more powerful than ever; it has introduced new ways to solve old problems and has gone on to become one of the fastest growing popular languages. It is now a de-facto choice for iOS developers and it powers most of the newly released and popular apps. This practical guide will help you to begin your journey with Swift programming through learning how to build iOS apps. You will learn all about basic variables, if clauses, functions, loops, and other core concepts; then structures, classes, and inheritance will be discussed. Next, you’ll dive into developing a weather app that consumes data from the internet and presents information to the user. The final project is more complex, involving creating an Instagram like app that integrates different external libraries. The app also uses CocoaPods as its package dependency manager, to give you a cutting-edge tool to add to your skillset. By the end of the book, you will have learned how to model real-world apps in Swift.

Adding Interactivity to Your First App


In this chapter, we have learned what an API is, the easiest way to consume one, and what we should do to start integrating a working backend in a mobile app. We improved the previous version of the Weather application and filled the UI with real data, which is fetched from The user can extend it by adding the five-day forecast for each city. The list of the cities should be loaded from a structure and all IDs should be in sync with the data provided from This is out of this scope of the book, but with the knowledge which we already have, it can be implemented easily.

We have used a standard way of communication and the more robust library—Alamofire. If you are creating a small app, you can stick to the pure iOS approach. But when you need a much more powerful solution straight out of the box, then Alamofire is what you are...
