This section tells you a few things you need to know before you get started, such as what youll need for hardware and software, where to find the project files for this book and more.

To follow along with this book, youll need the following:

• A Mac computer with an Intel/ARM processor. Any Mac that youve bought in the last few years will do, even a Mac mini or MacBook Air.

• Xcode 13 and Swift 5.5: Xcode is the main development tool for writing code in Swift. You'll need Xcode 13 at a minimum, since that version includes Swift 5.5. You can download the latest version of Xcode for free from the Mac App Store.

• Optionally, an iPhone, iPad, or iPod touch running iOS 15.

We would like to thank Matthijs Hollemans as one of the original authors of this book.He is a mystic who lives at the top of a mountain where he spends all of his days and nights coding up awesome apps. Actually he lives below sea level in the Netherlands and is pretty down-to-earth but he does spend too much time in Xcode. Check out his website at www.matthijshollemans.com.

This section introduces you to the first of the four apps you'll build over the course of this book Bull's Eye.

As you progress through building the Bull's Eye app, the section will teach you how to think like a programmer and how to plan your programming tasks. In addition, you'll also learn how to use Xcode, Interface Builder, and even the basics of coding for iOS.

While some of the concepts in this section might seem a bit basic, please do not skip this section if you are new to iOS development you will learn some fundamentals which act as the building blocks for what you learn later.

Hi, welcome to The UIKit Apprentice: Beginning iOS Development with Swift, Second Edition, the swiftest way if you'll pardon the pun to iOS development mastery!

In this book, you'll learn how to make your own iPhone and iPad apps using Apples Swift programming language (and Xcode 13) and the iOS UIKit framework, by building four interesting iOS apps.

Everybody likes games, right? So, youll start by building a simple but fun iPhone game named Bulls Eye. It will teach you the basics of iPhone programming, and the other apps will build on what you learn there.

Taken together, the four apps that you'll build cover everything you need to know to make your own apps. By the end of the book, youll be experienced enough to turn your ideas into real apps that you can put on the App Store!

Even if youve never programmed before, or if youre new to iOS, you should be able to follow along with the step-by-step instructions and understand how these apps are made. Each chapter has a ton of illustrations to prevent you from getting lost. Not everything might make sense right away, but hang in there and all will become clear in time.

Writing your own iOS apps is a lot of fun, but its also hard work. If you have the imagination and perseverance, there is no limit to what you can make your apps do. It is my sincere belief that this book can turn you from a complete newbie into an accomplished iOS developer, but you do have to put in the time and effort. By writing this book, Ive done my part. The rest is up to you...
