## What it is
LSAnimator (Objective-C) and CoreAnimator (Swift) are iOS animation libraries that let developers write complex multi-chain animations in a readable, chainable DSL. It is inspired by JHChainableAnimations and supports UIView and CALayer property animations.

## Use cases
- chain multiple uiview animations in swift
- write readable spring animations in objective-c
- animate calayer properties sequentially
- replace nested uiview animate completion blocks
- create multi-step animation sequences with easing

## When to choose
- you build iOS apps in Objective-C or Swift and want concise, maintainable chained animations
- you find native CAAnimation/UIView animation APIs too verbose for complex sequences

## When to avoid
- you target platforms other than iOS
- you need cross-platform (Android, Flutter, React Native) animation support
- you need very recent maintenance or latest iOS SDK guarantees

## Facets
- artifact type: library
- maturity: maintenance
- function: animation
- domain: mobile-development, graphics, web-development
- platform: -
- tags: objective-c, uikit, calayer, dsl, chainable-animations, cocoapods, carthage, ios, swift, mobile
