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


The reader knows how to create an app that solves real-world problems. He/she can develop the initial idea on paper and then try to create the UI in the storyboard. This version is called the early prototype. The reader can experiment with different screen sizes and make the UI work on different screens. We've practiced a nice way to add interactivity and link together different screens. Transition and passing information between screens is a technique that is used in all apps and we have discussed this in detail. We have used the standard iOS toolkit and sample data. The data used here simulates how our app will behave once real data is loaded.

The next chapter discusses modern software development using open source projects. It will show how easy it is to link together several projects using CocoaPods, one of the most popular dependency managers for Swift and Objective...
