Performing common image manipulation tasks using the iOS SDK can get quite messy. Here’s a Swift based library called Toucan that provides a nice clean API for common image processing tasks from Gavin Bunney.

The features of Toucan include:

• Image resizing with scaling, rotation, and cropping
• Image masking with circles, rectangles or custom images
• Borders with customizable width and color
• Easy chaining of the different image processing stages
• Examples showing how to perform each operation, and their combinations

You can find Toucan on Github here.
