objz

objz is a Zig interface to libojbc, the C library implementing the Objective-C runtime. objz provides Zig types for libobjc primitives.

To add this package to your project, pick a commit hash <hash> and run this:

$ zig fetch --save https://github.com/ryleelyman/objz/archive/<hash>.tar.gz

Then in your build.zig you can add this:

const objz = b.dependency("objz", .{
    .target = target,
    .optimize = optimize,
    .add_paths = false // adds macOS SDK paths; defaults to false
});

// For whatever you're building; in this case let's assume it's called exe.
exe.root_module.addImport("objz", objz.module("objz"));

and in your source code:

// import
const objz = @import("objz");

// get a class, create an object, etc.
const NSObject = objz.getClass("NSObject") orelse return error.Failed;
const object = NSObject.msgSend(*objz.Id, "alloc", .{});
defer object.msgSend(void, "release", .{});
object.msgSend(void, "init", .{});
