## What it is
Sica is a Swift library providing a simple, type-safe interface over Apple's Core Animation framework. It lets developers run animations sequentially or in parallel with support for easings, springs, and transitions.

## Use cases
- animate views sequentially in ios
- run parallel core animations with swift
- add spring animations to views
- apply easing functions to animations
- chain view animations with delays
- type-safe animation library for ios

## When to choose
- you want a type-safe Swift wrapper around Core Animation
- you need to compose animations in sequence or parallel
- you target iOS, tvOS, or macOS with Swift

## When to avoid
- you need cross-platform (Android/web) animation support
- you prefer SwiftUI's built-in animation APIs
- you need a very actively maintained library - last release was 2021

## Facets
- artifact type: library
