Simple RxSwift extensions for interacting with Apple APIs.

The <~ subscribes an observer to an observable. Observer can be any ObserverType, Variable, or (value)->()closure. Observable can be any ObservableType, Variable, or ObservableConvertibleType. This operator returns a Disposable.

The ++ appends a Disposable to a collection of disposables (DisposeBag or CompositeDisposable) and returns the collection.

These operators used in combination result in an easy to visualize data flow:

static func bindView(view: View, model: Model, selectionHandler:(SearchResult)->()) {
	view.rxs.disposeBag
		++ view.searchResults <~ model.searchResults
		++ model.searchTerm <~ view.searchTerm
		++ selectionHandler <~ view.selectionEvents
}

RxSugar adds Sugar to all NSObjects as a property called rxs. The rxs property contains RxSwift bindings for many common APIs. Here are a few examples:

object.rxs.disposeBag - a collection of dispoasables that will be disposed on deinit

button.rxs.tap - an Observable<Void> that sends an event on every .TouchUpInside control event.

textField.rxs.text - a ValueBinding<String> that sends an event on every .EditingChanged control event and sets the control's text for every event sent to it.

textField.rxs.attributedText - a ValueBinding<NSAttributedString> that sends an event on every .EditingChanged control event and sets the control's attributedText for every event sent to it.

Same as UITextField, but using the UITextViewTextDidChangeNotification to drive events

TargetActionObservable and ValueBinding provide the building blocks for creating your own interface "sugar" similar to the examples above.
