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<Object, Owned> = unsafe { Id::new(obj).unwrap() };

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

See [the docs](https://docs.rs/objc2/) for a more thorough overview, or jump

This crate is part of the [`objc2` project](https://github.com/madsmtm/objc2),
