Everyone at the Pragmatic Bookshelf, thank you for helping me write this book. I dreamed about this for a very long time, and now its true. Im so happy and proud.

Thank you, Adaobi Obi Tulton, for all your help and great suggestions. The book is so much better because of it, and it was a blast to work on this with you.

Thank you, Dave Thomas and Andy Hunt, for making me a better programmer and for creating The Pragmatic Bookshelf. I am very grateful to be part of it.

A big thank you to my technical editors, Manuel Carrasco Molina, Scott Davis, Jeff Kelley, Marcus Kida, Kilian Koeltzsch, Nathan Mattes, Klaus M. Rodewig, Sven Schmidt, Jeremy Sydik, and Donny Wals. Without you the book would not be half as good. Especially, thank you, Jeremy Sydik, for pointing out some major flaws in the first draft.

Thank you, Isa. You are the best wife on earth! Thank you for tolerating me during this time (and in general). Im sorry that I often didnt listen properly because I was thinking about the book. Thank you, my two children, for your patience when I was busy writing just one more sentence.

Learning new skills works best when its fun. You dive deeper and deeper. Hours pass and you cant stop reading and experimenting.

But theres also the outside world. And theres the feeling you have after a nice walk in the woods. Wouldnt it be cool if you could combine learning about iOS development with being outside?

This book features four inspiring projects you get to test outside. Youll draw on a map by moving in the real world, measure the length of a swing while swinging, measure how long someones outside, and share augmented reality views. As we build these projects, well also be looking at the three main approaches to constructing user interfaces: storyboards, code, and SwiftUI.

This book is for developers who already have rudimentary experience with iOS development and want to learn about GPS, sensors, and ARKit. And even if you already have experience with location-based tools, the projects in this book might give you new ideas for your own apps.

I assume that you already have Xcode installed and know the basics about its structure. If you have worked through a beginners book or other beginner resources, you are perfectly prepared to work through the projects in this book. The first three chapters, in particular, cover in detail what you have to do in Xcode to follow along.
