QRCodeReader.swift

Provides a ready-to-use view controller with camera overlay, torch button, and camera switch, eliminating complex AVFoundation setup as shown in the screenshot and code examples.

Supports both delegate and closure patterns for scan results, allowing developers to choose their preferred integration method, as demonstrated in the usage snippet.

Through the QRCodeReaderDisplayable protocol, developers can fully customize the interface, including custom views and constraints, enabling branded UI designs.

Leverages AVFoundation to decode multiple machine-readable code types, such as QR, PDF417, and Aztec, by specifying metadataObjectTypes in the builder.
