## What it is
STTextView is a performant, reusable text view component for macOS and iOS built on TextKit 2, serving as an NSTextView/UITextView replacement. It includes features like line numbers, multi-cursor editing, search/replace, and plugin support for syntax highlighting.

## Use cases
- build a source code editor for macOS or iOS
- replace NSTextView with a faster TextKit 2 text view
- display line numbers in a text editing component
- implement multi-cursor text editing in a Swift app
- add syntax highlighting to a custom text editor
- create a performant text editor with search and replace
- show invisible characters and custom annotations in a text view

## When to choose
- you need a performant text editing component on Apple platforms
- NSTextView/UITextView with TextKit 2 is too buggy or slow for your use case
- you want line numbers, multi-cursor, or plugin extensibility out of the box
- you are building a code editor or IDE-like app in Swift

## When to avoid
- you need a cross-platform (non-Apple) text editor
- you only need simple, short text input where UITextView/NSTextView suffices
- you require TextKit 1 compatibility or older OS versions than macOS 14 / iOS 16
- you need a full IDE with project management rather than a text view component
