## What it is
A custom UICollectionView layout for iOS written in Objective-C that lets users reorder cells by long-pressing and dragging them. It supports large/triplet item sizing, section spacing customization, and drag event delegate callbacks.

## Use cases
- reorder collection view cells by dragging
- build an iOS grid where users can rearrange items
- add long-press drag-and-drop to a UICollectionView
- customize collection view layout with large and small items
- receive callbacks when items move between positions

## When to choose
- you maintain an older Objective-C iOS codebase needing drag-to-reorder collection views
- you want a lightweight CocoaPods drop-in layout with delegate-based customization

## When to avoid
- you are starting a new project - the author recommends RAReorderableLayout instead
- you need horizontal scrolling collection views
- you need actively maintained Swift-first solutions
