EFQRCode is a lightweight, pure-Swift library designed for generating visually appealing QR codes with the option to add watermarks or icons. This versatile tool is built on CoreGraphics, CoreImage, and ImageIO, offering a seamless way to create and recognize QR codes across iOS, macOS, and tvOS platforms. EFQRCode supports integration via CocoaPods, Carthage, and Swift Package Manager, ensuring flexibility in your development workflow.

When utilizing EFQRCode, consider selecting high-contrast foreground and background color combinations to enhance readability. Opting for magnification over size can boost the definition of the QR code image, with the ability to adjust the values accordingly. It's crucial to strike a balance, as excessive magnification, lengthy sizes, or excessive content may lead to generation issues. Prior to deployment, it's advisable to test the QR code image thoroughly to ensure functionality.
