Mantis vs react-navigation

Mantis is an open‑source image cropping library for iOS and Mac Catalyst, written in Swift and usable from both UIKit and SwiftUI. It is designed to be embedded directly into host applications, giving developers a native‑look cropping UI without building it from scratch. The library supports freeform and fixed‑ratio crops, custom shapes, rotation, flipping, perspective correction, and full undo/redo stacks, all under a permissive free license. It integrates smoothly with common development tools and version‑control systems, making it ideal for iOS development teams.

React Navigation is a popular library for routing and navigation in React Native and Web apps. It provides a simple and intuitive API for managing navigation flows, making it easy to build complex navigation systems.
