## What it is
A Swift library for iOS that manages hiding and showing a view controller's navigation bar (and optionally tab bar, toolbar, or extension views) as the user scrolls. It integrates with UIScrollView delegates to provide smooth, automatic bar transitions.

## Use cases
- hide the navigation bar when scrolling a table view
- show and hide tab bar on scroll in iOS app
- collapsing toolbar effect for iOS
- hide nav bar and toolbar together while scrolling
- scroll-driven navigation bar animation in Swift
- maximize screen space for content while scrolling

## When to choose
- building an iOS app in Swift with UIKit scroll views that should reclaim screen space
- you want a simple manager class to wire into existing view controllers
- you need combined hiding of navigation bar with tab bar or toolbar

## When to avoid
- building with SwiftUI where native scroll behaviors may suffice
- you need highly customized or non-standard bar transitions
- project requires actively maintained dependencies with frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation
- domain: mobile-development
- platform: -
- tags: navigation-bar, tab-bar, scrolling, uikit, cocoapods, carthage, user-interface, ios, swift
