SwiftEventBus is a small, thread-safe publish/subscribe event bus library for Apple platforms, built on NotificationCenter with a cleaner API. It lets iOS, macOS, tvOS, and watchOS components communicate via named events without direct references or delegate wiring.

Use cases

• decouple ios view controllers with a pub/sub event bus
• post events to the main thread from background work
• replace messy NotificationCenter stringly-typed observers
• broadcast events across app components without delegates
• auto-unregister subscribers when a target is deallocated
• deliver notifications on background threads or custom queues

When to choose

• you want simple named-event pub/sub across Swift components
• you need thread-aware delivery (main thread, background, custom queues)
• you want lifecycle-friendly observer cleanup with one unregister call
• you need a Foundation-only library usable on all Apple platforms via SPM

When to avoid

• you need strongly-typed events rather than name-based notifications
• you prefer reactive frameworks like Combine or RxSwift
• your app architecture already uses delegates or Combine pipelines
• you need event delivery guarantees or persistence
