AppKit (macOS UI Framework)

AppKit is Apple's framework for building the graphical user interface of macOS applications. It provides developers with tools and components—like windows, buttons, menus, and text fields—to create visually consistent and functional software. Think of it as the toolkit enabling apps to display their content and interact seamlessly with users, following macOS design standards. AppKit handles user inputs, manages visuals, and ensures smooth performance, allowing developers to focus on the app's unique features while maintaining a native, polished user experience.
