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.

Structures, Classes, and Inheritance

In this chapter, we will get familiar with structures and classes. At the end, you should feel comfortable defining your own class or inheriting from any class that is part of iOS and could be inherited.

Now let's dive into structures and classes in Swift. Then, we will continue with two different techniques used to add extra functionality to a class—inheritance and extensions. The chapter discusses the MVC design pattern and why it is good to use it.

In this chapter, we will cover the following topics:

  • Structures
  • Classes
  • Inheritance
  • Model-View-Controller (MVC)
