## What it is
Persei is a Swift library by Yalantis that adds an animated, draggable top menu to UITableView, UICollectionView, or UIScrollView on iOS. It provides a MenuView with configurable MenuItem items and delegate-based selection handling, distributed via CocoaPods and Carthage.

## Use cases
- add an animated dropdown menu to a table view header
- create a draggable top menu for a collection view
- implement a custom animated menu in a scroll view
- build a filter selector menu for an iOS feed
- add a pull-down menu with icons to an iOS app

## When to choose
- you need a polished animated top menu for iOS scroll-based views
- you want a lightweight Swift component with CocoaPods/Carthage support
- you want a proven UI component from a design-focused team

## When to avoid
- you need a menu outside UITableView/UICollectionView/UIScrollView
- you need actively maintained Swift 6 or SwiftUI support
- you target platforms other than iOS
