## What it is
BouncyLayout is a Swift UICollectionViewLayout that makes collection view cells bounce using UIKit dynamics. It works with any UICollectionView, supports horizontal and vertical scrolling, and offers a configurable bounce effect.

## Use cases
- add a springy bounce effect to my collection view cells
- make a UICollectionView layout feel playful with UIKit dynamics
- create a bouncy scrolling list in an iOS app
- customize a spring animation for collection view layouts
- drop-in replacement for UICollectionViewFlowLayout with bounce

## When to choose
- you want a fun, physics-based bounce effect on iOS collection views
- you need a drop-in layout that works with any existing UICollectionView
- you prefer a pure Swift, MIT-licensed library with CocoaPods/Carthage/SPM support

## When to avoid
- you need a layout that is actively maintained with recent updates
- your project targets platforms other than iOS/UIKit
- you need complex layout features beyond bounce, like custom decorations or multi-section transforms
