Overview of this book

This book starts at the beginning by introducing programming through easy to use examples with the Swift Playgrounds app. Kids are regularly encouraged to explore and play with new concepts to support knowledge acquisition and retention – these newly learned skills can then be used to express their own unique ideas. Children will be shown how to create their first iOS application and build their very own movie night application.

The way that an iPhone will read our recipe is to go through it line by line, beginning from the top and moving to the bottom, just as we would normally do with a text, book, or recipe. Maybe you already noted it in our earlier playgrounds that anything we print to the console will be printed in the same order as Xcode reads our code, line by line, from the source editor.
