## What it is
A Swift library implementing a guillotine-style custom view controller transition animation for iOS menus, distributed via CocoaPods. It provides a transition animator and protocol for presenting a menu that drops down from the navigation bar.

## Use cases
- add a guillotine drop-down menu animation to an iOS app
- implement custom view controller transition animations in Swift
- animate a menu dropping from the navigation bar
- create a custom modal presentation style for a menu view controller
- find an iOS menu transition animation library

## When to choose
- you want a distinctive guillotine-style menu transition on iOS
- your project uses Swift and CocoaPods and targets iOS 8+
- you need a small, drop-in transition animator rather than a full UI framework

## When to avoid
- you need a maintained library with recent updates (last release 2020)
- you are building for Android or cross-platform
- you need a full menu component with built-in content, not just the transition animation

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components, mobile-framework
- domain: mobile-development, frontend, web-design
- platform: -
- tags: transition-animation, menu, uiviewcontroller, cocoapods, swift, ios, mobile
