Spring is a Swift animation library and iOS view animation framework. It provides a spring physics animation engine designed to generate realistic, organic motion for user interface movements. The framework utilizes a declarative animation interface, allowing developers to define animation properties and behaviors without writing complex imperative code. This includes a declarative animation workflow where motion is configured through visual storyboards. The system manages iOS UI animations and Swift view transitions, specifically automating how views appear and disappear through triggered a

Pop is an animation library for iOS and macOS designed to manage property animations, value interpolation, and physics engines. It functions as a framework for linking animation engines to arbitrary object properties, extending beyond standard view attributes. The library features a physics-based animation engine that generates motion based on velocity, friction, and target values. This system enables the creation of spring and decay animations to simulate real-world dynamics. The project also provides tools for value interpolation using easing curves, display-link driven updates synced to s

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

ViewAnimator is a Swift animation library and view transition framework designed to coordinate visual motion effects across interface elements. It provides a motion engine that executes animation sequences and geometric transforms on individual views and layout cells. The framework is built around a standardized animation protocol, allowing developers to create and integrate custom movement and transition behaviors. This extensibility enables the creation of reusable animation libraries beyond the pre-defined effects. The system supports combining multiple visual transforms into single compo
