## What it is
An Objective-C library that extends UICollectionViewFlowLayout to support drag-and-drop reordering of collection view cells, similar to the long-press interaction in iBooks. It provides delegate and data source protocols for handling cell moves and edge auto-scrolling.

## Use cases
- reorder cells in a uicollectionview with long press drag
- implement drag-and-drop grid like ibooks on ios
- let users rearrange items in a collection view layout
- auto-scroll collection view while dragging a cell to the edge
- add drag-to-reorder to an objective-c ios app

## When to choose
- you need iBooks-style cell reordering in a UICollectionViewFlowLayout-based grid
- you are maintaining an older Objective-C or pre-iOS 9 codebase without native drag-and-drop

## When to avoid
- you target modern iOS where UICollectionView's native drag-and-drop APIs exist
- you use SwiftUI or a non-flow collection layout
- you need actively maintained software with recent releases

## Facets
