Overview of this book

Over the last few years, we’ve seen a breakthrough in mobile computing and the birth of world-changing mobile apps. With a reputation as one of the most user-centric and developer-friendly platforms, iOS is the best place to launch your next great app idea. As the official tool to create iOS applications, Xcode is chock full of features aimed at making a developer’s job easier, faster, and more fun. 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.

Pre-production


As much fun as it would be to just dive in and start writing code, things usually go a bit smoother if we spend a little time thinking about what we are about to do. First, we're going to go on a mental journey through using the app to determine all of the features that will be present in the finished product. Then we're going to consult a designer (that's going to be me) to determine what the app will look like, and collect any assets we might need. Finally, we're going to break that feature list down into a development plan that gives us an idea of the actual tasks that will need to be completed to deliver each feature.

Assembling a feature list

As I mentioned earlier, the app we're going to create is a notes-style application called Snippets. The core feature of the app is that it lets the user make little snippets of life to save for later, which consist of text or images, or maybe later even web links or audio. Then the user can scroll through their snippets in reverse...
