## What it is
CodeScanner is a SwiftUI library providing a CodeScannerView struct that scans QR codes, barcodes, and other code types using the device camera. It wraps AVFoundation scanning into a simple declarative view with completion callbacks and customization options.

## Use cases
- scan qr codes in a swiftui app
- read barcodes with the iphone camera
- add a code scanner view to an ios app
- scan multiple codes continuously
- simulate qr scanning in the ios simulator

## When to choose
- you are building an iOS app with SwiftUI and need camera-based code scanning
- you want a simple drop-in scanner view with scan modes and simulator support

## When to avoid
- you need code scanning on Android or non-Apple platforms
- your app is not using SwiftUI
- you need to scan codes from images rather than a live camera feed

## Facets
