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

use objc2::{class, msg_send, msg_send_id};
use objc2::ffi::NSUInteger;
use objc2::rc::{Id, Owned};
use objc2::runtime::Object;

let cls = class!(NSObject);
let obj: Id<Object, Owned> = unsafe { msg_send_id![cls, new] }.unwrap();

let hash: NSUInteger = unsafe { msg_send![&obj, hash] };
println!("NSObject hash: {}", hash);

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