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.

How to Use Data Structures, OOP, and Protocols

In this chapter, we will begin with a short introduction of the primary collection types—array, set, and dictionary. Then, we learn how to visually present a collection. Finally, we will finish with a real application that displays information using a list. In the implementation, we will use OOP and protocols to handle the visualization of the data in an elegant fashion.

In this chapter, we will cover the following topics:

  • Primary collection types
  • List of items in a playground
  • Table view in iOS app
  • Protocols
