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.

Adding Interactivity to Your First App


In this chapter, we refreshed our knowledge of the default data structures array, dictionary, and set. We understood how to model real data and present it in using UICollectionView. We saw a working example in a playground and we created a single view which shows a list of cities and countries in an iOS app. In the end, we decided to add search functionality to this single screen.

After reading this chapter, you will have a deeper understanding of OOP and data structures. Each structure should be used when certain constraints are met. There are many other structures that may fit better when solving a particular problem. The best solution is to explore the problem and then pick the best match.

In the next two chapters, we will apply what we have learned so far. Namely, we will implement a small weather app, which consumes data from a public API, visualizes it in a nice...
