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.

Creating a Minimal Mobile App

In this chapter, we are going to develop our first mobile app using Xcode and our basic Swift knowledge. We will get familiar with the basic organization of an iOS project. We will run it in a simulator, which will be our first friend through the development process. A Git version control system will be introduced, because it's part of Xcode. With it, through the development process, we can track our changes to the source code. Then, at some point, we can easily switch back to a specific version. We will learn how to keep our code under control and to jump to a specific version, developed earlier by us.

In this chapter, we will cover the following topics:

  • Developing our first mobile app using Xcode
  • Git
