## What it is
Spring is a Swift library that simplifies iOS animations with prebuilt effects like shake, pop, squeeze, and slide, configurable via code or Storyboard. It supports chaining animations and property tuning such as force, damping, and delay.

## Use cases
- add spring animations to iOS views
- animate UIViews in Swift without writing Core Animation code
- configure animations from Storyboard
- chain sequential animations in Swift
- add fade, zoom, and slide transitions to an iOS app

## When to choose
- building an iOS app in Swift that needs polished view animations
- you want animation setup directly in Storyboard with autostart and autohide
- you prefer simple one-line animation APIs over raw Core Animation

## When to avoid
- building for platforms other than iOS
- you need SwiftUI-native animation APIs
- the project requires actively maintained dependencies, as updates are infrequent

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components
- domain: mobile-development, web-design
- platform: -
- tags: ios-animations, swift, storyboard, cocoapods, ui-animations, ios, mobile
