RKNotificationHub is a customizable badge UI library and a reusable SwiftUI notification badge component. It provides a view modifier and wrapper designed to attach numeric or dot notification indicators to any user interface element within a mobile application.
The library enables the management of notification badge displays, including the ability to customize colors, frame positions, and scales relative to parent views. It includes a system for badge count management to update activity indicators through incrementing, decrementing, or explicitly setting the count.
The project covers the broader domain of app notification UI and interface activity tracking. It utilizes state-driven updates and coordinate-space relative positioning to ensure consistent alignment of badges across different screen sizes and themes.
