lottie-ios is a vector graphics engine and animation framework for iOS that renders animations exported from After Effects as native visual elements. It functions as a renderer that converts animation data into high-fidelity native shapes to maintain small file sizes on mobile devices.
The framework provides tools for managing playback, looping, and real-time property updates. It allows for the modification of colors, positions, and keyframe properties of active animations to respond to application state changes.
The system parses JSON-based animation data and maps keyframes to native layers for hardware-accelerated drawing. It covers capabilities for animation playback control, keyframe-based interpolation, and the synchronization of frame updates with the system display refresh rate.
