## What it is
Pow is an open-source Swift package providing delightful SwiftUI transitions and change effects for iOS apps. It offers a collection of ready-made animations like pop, glow, and spray that can be added with a single line of code.

## Use cases
- add animated transitions to a SwiftUI view
- trigger a particle effect when a like count changes
- make my iOS app feel more polished with animations
- add haptic feedback when a value updates
- find prebuilt SwiftUI transitions instead of writing custom ones
- animate a view appearing with a pop or glow effect

## When to choose
- you build SwiftUI apps on iOS 15+ and want polished, one-line animations
- you want native-feeling transitions that integrate with SwiftUI's Transition API
- you want effects that trigger on value changes, including haptics

## When to avoid
- you target platforms below iOS 15 / macOS 12
- you need UIKit-only or cross-platform (non-Apple) animation tooling
- you need highly custom, non-preset animation choreography

## Facets
- artifact type: library
- maturity: active
- function: animation, ui-components
- domain: mobile-development, frontend, web-design
- platform: cross-platform
- tags: swiftui, transitions, effects, particles, haptics, swift-package-manager, visionos, ios, swift, mobile
