This book will take you from complete novice to a published app developer, and covers every step in between. You’ll learn the basics of iOS application development by taking a guided tour through the Xcode software and Swift programming language, before putting that knowledge to use by building your first app called “Snippets.” Over the course of the book, you will continue to explore the many facets of iOS development in Xcode by adding new features to your app, integrating gestures and sensors, and even creating an Apple Watch companion app. You’ll also learn how to use the debugging tools, write unit tests, and optimize and distribute your app. By the time you make it to the end of this book, you will have successfully built and published your first iOS application.

Summary


In this chapter, we learned how to find our way through the sometimes intimidating interface of Xcode. We broke down all the different sections, learned about the many different toolbars and editors, and tested our knowledge by building a simple iOS app! We should now have a really good idea of what different parts of the application are called, and we even have a few handy keyboard shortcuts to speed things up.

In the next chapter, we'll be taking a little break from Xcode and diving headfirst into the world of Swift programming. We'll start from the beginning, looking at how variables and functions work in Swift, but quickly work our way up to some of the powerful and unique features the language has to offer, such as optional types, closures, and generics. We'll also take a look at the new features that Swift 3 has to offer, such as error handling and protocol extensions.
