## What it is
An Objective-C and Swift library that provides a chainable, readable syntax for building UIView and CAAnimation sequences on iOS and tvOS. It replaces deeply nested UIView animation blocks with fluent one-line animation chains including easing, springs, repeats, and pre/post hooks.

## Use cases
- chain multiple UIView animations without nested completion blocks
- animate a view with spring physics then change its color
- write readable animation code in Objective-C or Swift
- pause and resume running animations
- repeat an animation sequence a number of times
- add hooks before or after each animation step

## When to avoid
- you are targeting SwiftUI declarative animations instead of UIKit
- the project needs actively maintained dependencies, since the latest release is from 2018
- you need cross-platform (Android, web) animation support

## Facets
- artifact type: library
- maturity: maintenance
- function: animation
- domain: mobile-development, frontend
- platform: -
- tags: objective-c, chainable-animations, uiview, cocoa-touch, ios, mobile, swift
