Converts your object into an observable object (provided your object can be converted). what are hot and cold observable sequences? This means that chocolates refers to an instance of BehaviorRelay. There are two ways to get this last emited value. And this is mostly because RxSwift doesn't enforce any particular architecture upon your app. ReactiveX is a collection of open source projects. Maybe RxSwift will have a typealias to keep the Variable name around, but to be on the safe side I used BehaviourRelay. In this article, we are going to use RxSwift library that provide reactive observable sequence to build our MVVM app. Relays. If you want to read more what are the differences between combineLatest, withLatestFrom and zip you can find an article here. Observer (callback) needs to be passed to ObservableType.subscribe method to receive sequence elements instead of calling next() on the returned iterator. Viewed 4k times 3.
