## What it is
A Swift library providing a protocol for UIViewControllers and UIViews to display placeholder views based on content, loading, error, or empty states. It manages the state machine for showing and hiding the appropriate placeholder automatically.

## Use cases
- show loading spinner while fetching data in ios view controller
- display empty state view when no content available
- show error placeholder when network request fails
- manage view states in uitableview or uicollectionview
- add placeholder screens to custom uiviews

## When to choose
- building an iOS or tvOS app in Swift that needs loading/empty/error placeholder views
- you want a lightweight protocol-based approach instead of a full UI framework

## When to avoid
- building for Android or cross-platform frameworks
- using SwiftUI rather than UIKit
- you need actively maintained dependencies - last release was 2020
