## What it is
AppDevKit is an Objective-C iOS development library from Yahoo providing everyday app development utilities across five sub-libraries: common tools, UI kit, animations, image views, and list views. It is distributed via CocoaPods and used in production Yahoo apps.

## Use cases
- add pull-to-refresh and infinite scrolling to iOS scroll views
- apply image filters and color replacement in an iOS app
- animate UIViews with simple macros
- cache nib instances in memory
- format strings from dates and numbers in Objective-C
- get the UIViewController for any UIView

## When to choose
- building or maintaining an Objective-C iOS app that needs battle-tested UI, animation, and list view helpers
- you want a permissively licensed (BSD) utility kit installable via CocoaPods
- you need to smooth over incompatibilities across iOS versions

## When to avoid
- starting a new Swift-first project where Swift-native libraries are preferred
- you need only one narrow feature that a dedicated library handles better
- your project no longer supports Objective-C dependencies

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation, image-processing, developer-tools
- domain: mobile-development, developer-tools
- platform: cross-platform
- tags: objective-c, cocoapods, uikit, yahoo, list-view, pull-to-refresh, ios, mobile
