Pop is an extensible animation engine for iOS, tvOS, and OS X that supports both static animations and dynamic spring/decay physics-based animations. It integrates with Objective-C or Swift codebases and can animate any property on any object.
Use cases
- add physics-based spring animations to iOS views
- create decay animations for scrolling interactions
- animate arbitrary properties on any object in Swift or Objective-C
- build realistic interactive animations like Facebook Paper
- add animations to tvOS apps
When to choose
- building iOS, tvOS, or OS X apps needing spring/decay physics animations
- working in Objective-C or Swift codebases that need a mature, well-tested animation engine
- needing to animate arbitrary properties beyond what Core Animation offers out of the box
When to avoid
- targeting platforms other than Apple's (iOS/tvOS/OS X)
- starting a new project, since the repo is archived and no longer actively maintained
- needing SwiftUI-native animation APIs
