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.

Developing a Simple Weather App

In this chapter, we will develop a Weather app. First, we will define all the screens in the storyboard, and learn how to open different view controllers and how to create custom animations between them. Finally, we will understand how to define constraints, and discuss how to pass information between two view controllers. This chapter covers the following topics:

  • Designing an application screen in the storyboard
  • Defining the model
  • Showing different screens when a button is pressed
  • Passing data between view controllers
  • Constraints and auto layout
  • Refreshing what we know about UITableView and UICollectionView

Let's begin the development of the Weather app with a definition and what the app should look like.
