## What it is
QRCodeReader.swift is a Swift library for iOS that provides a simple QR code and machine-readable code scanner built on Apple's AVFoundation framework. It includes a ready-made view controller with camera view, scan area overlay, and camera switching controls.

## Use cases
- scan QR codes in an iOS app
- read barcodes using the device camera
- build a QR scanner view controller with overlay
- switch between front and back cameras while scanning
- replace ZXing or ZBar with a native Swift scanner

## When to choose
- you need a lightweight native Swift QR/barcode scanner on iOS 8+
- you want a prebuilt scanner view controller with customizable overlay and buttons
- you prefer AVFoundation-based scanning over third-party native ports

## When to avoid
- you need QR code generation, not scanning
- your app targets platforms other than iOS
- you need scanning features beyond AVFoundation's supported metadata types
