WARNING: This library is basically completely untested at this point

Objc_asyncio is a library that implements an asyncio runloop using the Cocoa CFRunLoop, which makes it possible to integrate macOS GUIs and asyncio.

The basic usage in command-line scripts is to call objc_asyncio.install and then use asyncio as usual.

The more interesting use-case are GUI programs using PyObjC, in which case you can use the running_loop context manager:

::

import sys import Cocoa

import objc_asyncio

with objc_asyncio.running_loop():

Cocoa.NSApplicationMain(sys.argv)
