Getting Started with EFQRCode

EFQRCode is a lightweight, pure-Swift library for generating stylized QRCode images with watermark or icon, and for recognizing QRCode from images, inspired by qrcode. Based on CoreGraphics, CoreImage, and ImageIO, EFQRCode provides you a better way to handle QRCode in your app, no matter if it is on iOS, macOS, watchOS, and/or tvOS. You can integrate EFQRCode through CocoaPods, Carthage, and/or Swift Package Manager.

Curious about what EFQRCode could do and how would it look like when used in your project? See our Cheat Sheet page, in which some useful code snippet are listed. There you can learn how to use EFQRCode in your project better.

At last, please also remember to check the full API Reference whenever you need to know more about EFQRCode.

Recommendations

1. Please select a high contrast foreground and background color combinations;
2. To improve the definition of QRCode images, increase size, or scale up using magnification (instead);
3. Magnification too high／size too large／contents too long may cause failure;
4. It is recommended to test the QRCode image before put it into use;
5. You can contact me if there is any problem, both Issue and Pull request are welcome.
