## What it is
An Objective-C UIKit category that collapses a UIView and its related Auto Layout constraints to simulate a flow-layout effect. It supports Interface Builder wiring via IBOutletCollection and auto-collapsing views like UILabel or UIImageView when their content becomes empty.

## Use cases
- collapse a view and its margins in an Auto Layout stack
- hide empty labels or image views in table view cells automatically
- simulate flow layout behavior for dynamic cell content
- toggle view visibility while keeping layout clean in Interface Builder
- remove spacing constraints when a component has no content

## When to choose
- you maintain a legacy Objective-C iOS codebase using Auto Layout
- you need Interface Builder-friendly collapsing of views and constraints
- you want views to auto-collapse when their content is empty

## When to avoid
- you use SwiftUI or modern UIKit stack views, which handle this natively
- you need an actively maintained library
- your project is in Swift and you prefer Swift-native solutions

## Facets
- artifact type: library
