# pyobjc-framework-libdispatch — Wrappers for libdispatch on macOS

License: permissive · Maintenance: active · Downloads: 823.3K/mo

## What it is and what it does

pyobjc-framework-libdispatch wraps Apple's libdispatch (Grand Central Dispatch) library for use in Python on macOS. It allows Python developers to access the same low-level concurrency primitives that native macOS applications use. The package is part of the PyObjC project and requires pyobjc-core and pyobjc-framework-Cocoa as runtime dependencies.

This is a thin binding layer—it does not include its own documentation, instead directing users to Apple's official dispatch documentation and PyObjC's general guidance on Objective-C to Python translation. It is useful when you need direct access to libdispatch from Python, typically in macOS-specific applications or when integrating with Cocoa frameworks. The package supports Python 3.10 through 3.15 and is actively maintained.

Use it for:

- Integrate Python code with Cocoa frameworks that expect dispatch-based concurrency.
- Build macOS desktop applications in Python that need access to native scheduling primitives.
- Coordinate operations between Python and Objective-C components in a hybrid codebase.
- Access libdispatch from Python when porting macOS applications or libraries.
- Work with pyobjc-framework-Cocoa in projects requiring dispatch queue integration.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to macOS's libdispatch (Grand Central Dispatch) framework, enabling access to Apple's concurrent task scheduling system from Python code.

Yes, if you are developing on macOS and need direct access to libdispatch or Cocoa framework integration. Active maintenance, recent releases, permissive MIT license, and zero known vulnerabilities make it safe. No, if you are on non-macOS platforms or can meet your needs with Python's built-in asyncio or threading modules.

## Install

pip install pyobjc-framework-libdispatch
uv add pyobjc-framework-libdispatch
poetry add pyobjc-framework-libdispatch

## Installing pyobjc-framework-libdispatch

Before you install: Medium install friction due to platform-specific wheels (macOS only, Python 3.10+). Active maintenance with recent releases; last commit 2026-08-14 and release 3 days old. Depends on pyobjc-core and pyobjc-framework-Cocoa.

License in practice: MIT license permits commercial and private use with minimal restrictions; straightforward permissive terms suitable for most projects.

Quickstart:

pip install pyobjc-framework-libdispatch

import pyobjc_framework_libdispatch

macOS only; requires Python 3.10 or later and a compatible CPython interpreter.

Verify before relying:

- What specific dispatch functions and APIs are exposed by this wrapper.
- Performance characteristics compared to Python's native asyncio or threading.
- Whether free-threading support (Python 3.13+) is fully tested and stable.
- Typical usage patterns and concrete examples beyond Apple's official dispatch documentation.
