## What it is
A deprecated Objective-C library providing a drop-in UIViewController subclass with a growing text input view and messaging features like autocomplete, typing indicators, and markdown formatting for iOS chat apps. Slack no longer maintains it, with the last release in 2018.

## Use cases
- build a chat message input view in an iOS app
- growing text view for messaging UI on iOS
- add @mention autocomplete to an iOS chat screen
- typing indicator for an iOS messaging app
- legacy Objective-C chat input component for iOS

## When to choose
- maintaining a legacy Objective-C iOS app already using it
- you need a battle-tested chat input for an old iOS codebase and accept no updates

## When to avoid
- starting any new iOS project
- you need Swift or modern iOS support
- App Store compliance matters, since it is unmaintained

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, form-handling
- domain: mobile-development, messaging-platforms, developer-tools
- platform: -
- tags: objective-c, deprecated, chat-ui, text-input, uiviewcontroller, cocoapods, ios, swift, mobile
