AppKit

AppKit is a framework developed by Apple that provides the tools and components needed to create applications for macOS. It manages the user interface elements such as windows, buttons, menus, and other visual components, and handles interactions like mouse clicks and keyboard input. By using AppKit, developers can build consistent, functional, and visually appealing software that integrates seamlessly with the Mac operating system. Essentially, it’s the foundation that allows developers to design and manage the graphical parts of Mac applications efficiently.
