## What it is
RazzleDazzle is a simple keyframe-based animation framework for iOS written in Swift, designed for scrollview-powered app intro animations. It also provides an AutoLayout-friendly paging scroll view controller that keeps views positioned across pages as layouts resize.

## Use cases
- add scrolling intro animations to an iOS app
- animate views based on scroll position with keyframes
- build a paging scrollview layout that survives rotation and split-screen
- pin a view across multiple pages while others scroll past
- port an Objective-C JazzHands intro to Swift

## When to choose
- you are building a scrolling app intro in Swift on iOS
- you want AutoLayout-friendly paging scrollview behavior
- you prefer a lightweight, battle-tested IFTTT library

## When to avoid
- you need complex standalone animations unrelated to scrolling
- your project is in Objective-C (use JazzHands instead)
- you need a library with frequent updates or modern SwiftUI support
