Swift iOS Programming for Kids

By: Steffen D. Sommer, Jim Campagno

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.

Having an understanding of how our iPhone reads our code as a line by line recipe can help us understand the need for the concept of a function.

When we run this application, it will simply output the simulation of making a pizza to the console:

How will we write our code if we want our program to make multiple pizzas? The first thing that comes to mind...
