EFQRCode is a pure-Swift, cross-platform Apple framework for generating stylized and highly customizable QR codes, and for recognizing QR codes from images. The core production code exposes two primary entry points: `EFQRCode.Generator` and `EFQRCode.Recognizer`. The generator accepts text/data input, encodes it using the external `QRCodeSwift` package, maps the resulting matrix through a strategy-based style hierarchy (`EFQRCodeStyleBasic`, `EFQRCodeStyleBubble`, `EFQRCodeStyleLine`, `EFQRCodeStyle25D`, `EFQRCodeStyleImage`, etc.), and produces SVG representations which are then rasterized by `SwiftDraw` into static images, PDFs, GIFs, APNGs, or AVFoundation-backed video files. The recognizer uses CoreImage-based detection with grayscale fallback and result caching. The library is heavily documented, supports iOS, macOS, tvOS, watchOS, and visionOS, and is distributed through SPM, CocoaPods, and Carthage. The `Examples/` directory contains demo apps for each platform that act as integration-style usage references, but these are example clients rather than the core deliverable. This is definitively an application/library repository; there are no data pipelines, notebooks, or research artifacts.
