It would be very hard work to handle the disposing manually, so RxSwift equips us with the DisposeBag. Observable represent class that can in any given period of time asynchronously produce sequence of events that can carry some data. However, the same principles could easily be implemented in other Rx implementations, if necessary. RxSwift is Lodash for events, or Underscore for events, if you’re coming from the JavaScript world. For the past months, I keep going further in RxSwift usage. And by the observing the Application's state (foreground, background) is necessary in my case as the with code that @CloakedEddy provided the ReplaySubject emitted all the events skipped while the app was on background. There are so many ways that objects can talk to each other in an iOS App: delegates, callbacks, notification.
