Ever thought about creating a [Swift playground book](https://developer.apple.com/library/content/documentation/Xcode/Conceptual/swift_playgrounds_doc_format/index.html)? If so, this is the learn guide for you!

In the process of creating a Swift Playground book for use with Adafruit's Bluefruit devices, I noticed that there's very little public information available on the subject. Hopefully this guide will help share what I've learned with the world.

In this learn guide we will:

• Give you a playground book template to get you started on project.

• Show you how to get started authoring your own playground book with bluetooth capabilities.

• Explain to you how a Playground book is structured.

## What you should know before beginning:

• You should have a basic understanding of the **Swift Programming Language** & **iOS**.

• You should be familiar with the **CoreBluetooth Framework**.

If you're not familiar with CoreBluetooth, check out the [Create Bluetooth LE App for iOS](../../../crack-the-code/overview?view=all) learn guide that shows you the fundamentals of the CoreBluetooth framework and transferring data.

## To create a Playground book you'll need:

• A Mac computer

• Xcode version 9.0 (or newer)

• Swift Playgrounds App

• An iPad running iOS 11 (or newer)

If all the requirements are met, let's get started!
