# pyobjc-framework-ExtensionKit — Wrappers for the framework ExtensionKit on macOS

License: permissive · Maintenance: active · Downloads: 634.9K/mo

## What it is and what it does

This package wraps Apple's ExtensionKit framework for use in Python, built on top of PyObjC. It allows Python developers on macOS to interact with native extension mechanisms that would otherwise require Objective-C or Swift. The bindings are thin wrappers without embedded documentation—users must consult Apple's official ExtensionKit documentation alongside PyObjC's general translation guides to understand how to use the framework.

The package depends on pyobjc-core and pyobjc-framework-Cocoa to provide the underlying bridge between Python and Objective-C. It is actively maintained and supports Python 3.10 through 3.15, including free-threading variants. Installation is restricted to macOS systems with pre-built wheels for specific Python versions and macOS versions.

Use it for:

- Build macOS applications in Python that need to integrate with the system's extension architecture
- Create system extensions or plugins that leverage ExtensionKit from a Python codebase
- Access ExtensionKit APIs from Python when wrapping or extending existing macOS applications

## Worth the install?

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

Provides Python bindings to macOS's ExtensionKit framework, enabling Python developers to access native extension capabilities on macOS through PyObjC.

Yes, if you are developing on macOS and need ExtensionKit access from Python. The package is actively maintained, carries no known vulnerabilities, and uses a permissive license. Install friction is moderate due to platform and Python version specificity, but wheels are available for current Python versions. Not applicable for non-macOS development.

## Install

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

## Installing pyobjc-framework-ExtensionKit

Before you install: Medium install friction due to platform-specific wheels (macOS only, multiple Python versions supported). Active maintenance with recent release (3 days old) and steady repository activity.

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

Quickstart:

pip install pyobjc-framework-extensionkit

import ExtensionKit
# Use ExtensionKit APIs through PyObjC bindings

macOS system required; Python 3.10 or later; appropriate wheel for your Python version and macOS version must be available

Verify before relying:

- Whether ExtensionKit support is available on all macOS versions the wheels target (10.9 through 10.15)
- Whether the wrapper covers the full ExtensionKit API surface or a subset
