## What it is
A collection of iOS 7 custom view controller transition animation controllers and interaction controllers written in Objective-C. It provides transitions like flip, fold, crossfade, explode, cube, and portal, which can be made interactive with swipe or pinch gestures.

## Use cases
- add custom flip or fold transitions between view controllers in an iOS app
- make navigation controller push/pop transitions interactive with swipe gestures
- create animated modal present/dismiss transitions
- add animated transitions to tab bar controller switching
- learn how iOS custom transition APIs work

## When to choose
- building an older Objective-C iOS app targeting iOS 7+ that needs custom view controller transitions
- wanting drop-in animation controllers with optional gesture-based interactivity
- learning how UIViewControllerAnimatedTransitioning and interaction controllers work

## When to avoid
- building a new app in Swift with SwiftUI or modern UIKit transition APIs
- needing actively maintained or supported code
- targeting platforms other than iOS

## Facets
