PyObjC MailKit Framework

The `pyobjc-framework-mailkit` library provides Python wrappers for the macOS MailKit framework. MailKit allows developers to extend the functionality of Apple Mail, primarily through Mail app extensions. As part of the larger PyObjC project, it enables Python applications to interact with native macOS Objective-C APIs. The current version is 12.1, with releases typically tied to macOS SDK updates and Python version compatibility.
