## What it is
Wave is a spring-based animation engine for iOS, iPadOS, and macOS built in Swift with no external dependencies. It provides fluid, interruptible animations whose velocity is preserved when retargeting mid-flight, usable from UIKit, SwiftUI, or AppKit.

## Use cases
- create fluid spring animations in UIKit
- make gesture-driven views that interrupt and retarget smoothly
- animate UIView and CALayer properties like frame, center, and scale
- build interactive drag-and-dismiss interfaces like picture-in-picture
- add bouncy, natural motion to SwiftUI views
- enable 120fps ProMotion animations on iOS

## When to choose
- you need interruptible, retargetable animations that preserve velocity
- you want UIView.animate-style APIs backed by springs
- you're building gesture-driven interactions on iOS or macOS
- you want a dependency-free Swift animation library

## When to avoid
- you only need simple one-shot animations that UIKit already handles
- you're targeting platforms outside Apple's ecosystem
- you need keyframe or path-based animation timelines
