objc2

Objective-C interface and runtime bindings for Rust.

Most of the core libraries and frameworks that are in use on Apple systems are written in Objective-C; this crate enables you to interract with those.

Example

```rust use objc2::{class, msg_send}; use objc2::rc::{Id, Owned}; use objc2::runtime::{Class, Object};

let cls = class!(NSObject); let obj: *mut Object = unsafe { msg_send![cls, new] }; let obj: Id = unsafe { Id::new(obj).unwrap() };

// TODO // let isa = unsafe { obj.ivar::("isa") }; // assert_eq!(cls, isa); ```

See the docs for a more thorough overview, or jump right into the [examples].
