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.

Summary

Let's try to recap what we have learned in this chapter so far. We started with an introduction to Firebase. Then, we integrated a basic login to our app using Firebase. We built the general structure of the app with stubbed screens. Next, the tab bar was customized using an external library, so it functions slightly differently and looks cool.
We implemented a Create Post screen, which is used to upload images to Firebase storage and save data in the real-time database on Firebase servers. The user flow was a nice mix of an external library and a view controller developed in the app. Finally, we discussed how easy it is to apply a CoreImage filter to an image.

In the last chapter of the book, we will continue our work on the Instagram-like app. We will create a nice-looking home screen and we will implement a Search screen. Then we will finish the profile screen...
