What is it?

Lottie for iOS loads vector animations exported from After Effects in the bodymovin JSON format and renders them natively in real time, without requiring designers to recreate the motion by hand. It supports iOS, macOS, tvOS and visionOS, and sits alongside sibling Lottie projects for Android and Web.

Because animations are stored as JSON, files stay small while still allowing complex motion. Playback can be controlled by resizing, looping, changing speed, reversing, playing a portion of the timeline, or scrubbing interactively. Properties such as color, position and other keyframable values can also be changed at runtime.

The library can be installed with Swift Package Manager, CocoaPods or Carthage. The project includes an example app with over 100 sample animations and a snapshot test suite.
