If you take a second to compare this to an existing operator, you'll soon see that it's essentially the same thing as flatMap.The main difference between the two is that andtThen is semantically more correct to use when you work with a Completable.. Operators; Combining; Merge; Merge combine multiple Observables into one by merging their emissions. Merge may interleave the items emitted by the merged Observables (a similar operator, Concat, does not interleave items, but emits all of each source Observable’s items in turn … Relays have been moved to a separate framework - RxRelay, and can be used without RxCocoa. Completable → CompletableObserver Flowable → DisposableSubscriber The reason why I mentioned Flowable at the last is that there are more details to cover in Flowable. RxSwift Combine Notes; AnyObserver: AnySubscriber: BehaviorRelay Simple wrapper around BehaviorSubject, could be easily recreated in Combine: BehaviorSubject: CurrentValueSubject: This seems to be the type that holds @State under the hood: Completable CompositeDisposable ConnectableObservableType: ConnectablePublisher: Disposable: Cancellable: DisposeBag: A … And this is mostly because RxSwift doesn’t enforce any particular architecture upon your app. ... -> Completable { return Completable.merge( data .flatMap { value -> Completable in method1(value) .map(method2) .filter { $0 != nil } .map { $0! } If immediate cleanup is required, we can just create a new bag. Once when your Completable completes, it is terminated. Deprecates `image(transitionType:)` in favor of `image`.
