Introduction

Learning new skills works best when it’s fun. You dive deeper and deeper. Hours pass and you can’t stop reading and experimenting.

But there’s also the outside world. And there’s the feeling you have after a nice walk in the woods. Wouldn’t 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. You’ll draw on a map by moving in the real world, measure the length of a swing while swinging, measure how long someone’s outside, and share augmented reality views. As we build these projects, we’ll also be looking at the three main approaches to constructing user interfaces: storyboards, code, and SwiftUI.
