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.

Playground

Before diving into a mobile project, we will start with a special type of project that will help us master the Swift language. These projects are a cool place to experiment, without the extra hassle of setting up a real mobile project. We can experiment with real mobile functions, without even working on a full mobile project. Playground projects are a really nice place to prototype algorithms or UI, and simply to have small building blocks, ready and fully tested, before plugging them into a mobile app.

What is a playground?

Straight from the file generated by Xcode:

"Playground – noun: a place where people can play."

Playground is a simple project, which can be used to practice, experiment, prototype...
