YapAnimator is a Swift physics-based animation library for iOS and macOS that makes it easy to animate any value representable as an array of Doubles, with interruptable animations, completion blocks, and gesture-driven forces. It is now archived and unmaintained, as Apple's built-in spring animations cover most use cases.

Use cases

  • animate view properties with physics-based springs in swift
  • add gesture velocity to interactive transitions
  • morph between bezier paths with animation
  • animate custom types like colors or volume in ios
  • create interruptable animations with completion blocks

When to choose

  • you maintain a legacy iOS/macOS app already using it
  • you need physics-based animation of arbitrary Double-representable values on older Apple platforms

When to avoid

  • starting a new project - use SwiftUI's .spring() or UIView spring animations instead
  • you need a maintained library with active support
  • you target non-Apple platforms
