Gifu

Gifu adds protocol-based, performance-aware animated GIF support to UIKit.

How It Works?

Gifu does not require using the built-in GIFImageView subclass. The Animator class does the heavy-lifting, while the GIFAnimatable protocol exposes the functionality to the view classes that conform to it, using protocol extensions.

The Animator has a FrameStore that only keeps a limited number of frames in-memory, effectively creating a buffer for the animation without consuming all the available memory. This approach makes loading large GIFs a lot more resource-friendly.
