ReactiveFoundation is a framework from ReactiveKit collection of frameworks that extends NSObject objects with type-safe KVO support and NSNotificationCenter with reactive observing mechanism. Consult ReactiveKit documentation to learn how to work with the Observables it provides.

let user = ObjCUserClass()

user.rValueForKeyPath("name").observe { (name: String?) in
  print(name)
}.disposeIn(rBag)

user.rValueForKeyPath("name").bindTo(nameLabel.rText)

Observing KVO-observable will be active as long as the returned disposable is alive. Make sure you store the disposable when using observe method on KVO-observable. You don't need to store the disposable when using bindTo method. Binding will be automatically disposed when the bindable target (i.e. view) is deallocated.

NSNotificationCenter.defaultCenter().rNotification("MyNotification").observe { notification in
  print("Did receive notificaton \(notification).")
}.disposeIn(rBag)

Make sure you always dispose observation when it's no longer necessary. The simplet way is to put the disposable into the disposable bag on the object that has initiated observation.

Dispose bag is provided by NSObject and all its subclasses and it is disposed when the object is deallocated. Use this to cleanup your observations.
