Learn Swift by Building Applications

By: Emil Atanasov, Giordano Scalzo, Emil Atanasov

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.

Getting Familiar with Xcode and Playgrounds

In this chapter, we will get familiar with Xcode, the Integrated Development Environment (IDE) that is used to develop iOS, macOS, tvOS, and watchOS apps. We will introduce a pretty neat way of playing with and exploring the Swift language called playground. We will see all the panels and the many different options that are available in Xcode. We will find an easy way to use templates and we will experiment with real Swift code in a playground.

In this chapter, we will cover the following topics:

Installing Xcode
Exploring playground
Different options available in Xcode
Markup items
