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.

List of items in a playground

In this chapter, we will get familiar with different collections of data. They are pretty useful for storing data in memory and to work with, but in many cases we should present a collection of the data to the user. In the previous chapter, we discussed some nice UI iOS components which can be used in our app. Now, we will learn how to present an array of values in a simple collection view. To show this, we will use a playground and do some experiments with the view.


UICollectionView is a visual component which presents ordered collections of data items using custom layouts. By default, iOS comes with one pretty robust layout—UICollectionViewFlowLayout which orders all...
