Mantis is a Swift image cropping library for iOS and Mac Catalyst offering UIKit and SwiftUI APIs with an Apple Photos-style crop experience. It supports rotation, flip, fixed and free aspect ratios, custom crop shapes, perspective correction, and undo/redo.
Use cases
- crop profile avatars in an iOS app
- add a Photos-style image cropper to SwiftUI
- let users straighten and rotate photos before upload
- apply perspective correction to document photos
- crop images to custom shapes like circles or hearts
- persist crop settings and re-crop later
When to choose
- you need a native iOS crop UI in UIKit or SwiftUI
- you want aspect ratio presets, rotation, flip, and undo/redo out of the box
- you need custom crop shapes or perspective correction
- you target iOS and Mac Catalyst with localization
When to avoid
- you need cross-platform (Android or web) cropping
- you need full photo editing beyond cropping, such as filters or adjustments
- your project is not Swift-based
