Lottie‑iOS is an open-source library by Airbnb that renders After Effects animations (in JSON or .lottie format) natively on Apple platforms, including iOS, macOS, tvOS, and visionOS. Written in Swift, it supports SwiftUI and UIKit integrations and enables fluid vector animations with minimal performance overhead.

...The architecture separates shape embedding (to understand user-drawn geometry) from motion embedding / generation (to produce temporally coherent movement). Users can provide rough keyframes or control constraints (pose anchors), and the system fills intermediate frames with fluid animation. The repository includes demonstration apps and notebooks where you can upload or draw shapes and watch animations play. Because the approach is data-driven, it generalizes to new drawings even with varying proportions or stylizations.

Wave is a spring-based animation engine for iOS, iPadOS, and macOS. It makes it easy to create fluid, interactive, and interruptible animations that feel great. Wave has no external dependencies, and can be easily dropped into existing UIKit, SwiftUI, or AppKit based projects and apps. The core feature of Wave is that all animations are re-targetable, meaning that you can change an animation’s destination value in-flight, and the animation will gracefully redirect to that new value.
