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.

We have been using open source projects, some of which are hosted on GitHub. But we don't need an account on GitHub to do that.

Once you are registered, you have to log in and open the following project: https://github.com/Yummypets/YPImagePicker.

This is the project that we are going to be using to pick an image from the gallery in our InstalikeApp. We will try to add the ability to modify the filters that are displayed on the filter page. At the moment, there is no way to change them easily. One option is to change the code in the Pods project, but this can't be easily shared with other developers working with this component.

Now, you have an account at GitHub, which can be...
