## What it is
Companion sample code repository for Bob McCune's book 'Learning AV Foundation', demonstrating Apple's AV Foundation framework in Objective-C. It provides hands-on examples covering audio and video playback, recording, editing, and media processing on Apple platforms.

## Use cases
- learn AV Foundation for iOS media apps
- sample code for playing audio and video on iOS
- examples of video recording and editing with AV Foundation
- understand AVAsset and media composition APIs
- follow along with the Learning AV Foundation book exercises

## When to choose
- you are reading the Learning AV Foundation book and want runnable examples
- you prefer Objective-C samples for Apple media frameworks
- you need reference implementations of AV Foundation playback, editing, or capture

## When to avoid
- you need Swift examples (use the companion Learning-AV-Foundation-Swift repo instead)
- you want a maintained library to add to your project rather than educational sample code
- you need coverage of the latest AVFoundation APIs introduced after the book's publication
