## What it is
Rust bindings to Apple's Core Foundation and other low-level macOS/iOS system libraries. It lets Rust code call native Apple platform APIs safely.

## Use cases
- call core foundation apis from rust
- build a macos app in rust
- access ios system libraries from rust
- ffi bindings for apple frameworks
- use nsstring and core types in rust

## When to choose
- writing Rust software targeting macOS or iOS that needs native system APIs
- building cross-platform Rust projects with Apple platform support

## When to avoid
- you need fully generated, exhaustive Apple API bindings rather than hand-picked ones
- targeting platforms other than macOS/iOS

## Facets
- artifact type: library
- maturity: active
- function: sdk, developer-tools
- domain: apple-ecosystem, developer-tools, cross-platform
- platform: rust
- tags: core-foundation, ffi-bindings, system-apis, objective-c, macos, ios
