Documentation

  1. Define Notification Name:

    extension Notification.Name {
    
        public static let Message = Notification.Name("Message")
    
    }
  2. Register and unregister your subscriber. For example on iOS, UIViewController should usually register according to their life cycle:

     func onViewWillAppear(_ animated: Bool) {
         super.onViewWillAppear(animated)
         EvenBus.shared.register(self, name: .Message) { [weak self] (object) in
             guard let _ = self else { return }
             
             if let text = object as? String {
                 print(text)
             }
         }
     }
     
     func onViewWillDisappear(_ animated: Bool) {
         super.onViewWillDisappear(animated)
         EvenBus.shared.unregister(self, name: .Message)
     }
  3. Post events:

    EvenBus.shared.post(name: .Message, object: "Hello EventBus")
