let loadNextPageTrigger = PublishSubject<Void>()

let loading = Variable<Bool>(false)


let nextPageRequest = loading.asObservable()

    .sample(loadNextPageTrigger)

    .flatMap { [unowned self] loading -> Observable<Int> in

        if (loading || self.pageStatus != true || self.netStatus != true) {

            return Observable.empty()

        }
        else
        {

            return Observable<Int>.create
                { [unowned self] observer in

                    print("self.pageIndex called",self.offset)

                    self.offset += 20

                    observer.onNext(self.offset)

                    observer.onCompleted()

                    return Disposables.create()

            }

        }

}

on returning obervable.empty() it terminates the Observable.

You need to manage your code using singleton.That keeps observable which will live throughout app. use from singleton class

How to keep an Observable alive after onError? · Issue #3870 , but they should keep receiving values after that; if a new subscription is performed after an error it should get the previous non-error result if any,  Rx is the most powerful library that I know when it comes to asynchronous operations. But you don’t always need to use Observables. Promises are still here, and it’s OK to use them when you have a single event as we saw in this article. That’s all! ☞

You could just avoid returning an observable in that situation:

let nextPageRequest = loading.asObservable()

    .sample(loadNextPageTrigger)

    .flatMap { [unowned self] loading -> Observable<Int> in 

            return Observable<Int>.create { [unowned self] observer in

                    print("self.pageIndex called",self.offset)

                    self.offset += 20

                    observer.onNext(self.offset)

                    observer.onCompleted()

                    return Disposables.create()

            }


}

Also if you need the status of that expression you could pass it as well:

let nextPageRequest = loading.asObservable()

    .sample(loadNextPageTrigger)

    .flatMap { [unowned self] loading -> Observable<(Bool, Int)> in 

            return Observable<(Bool, Int)>.create { [unowned self] observer in

                    print("self.pageIndex called",self.offset)

                    self.offset += 20

                    let status = loading || self.pageStatus != true || self.netStatus != true

                    observer.onNext(status, self.offset)

                    observer.onCompleted()

                    return Disposables.create()

            }


}

How to keep an Observable alive after Error in Angular?, Observable and Observer sign a contract through the subscription which will be called whenever the click event is fired but error() and complete() will We get a response. it passes through catchError() because it does not  Observables can have multiple values over time Now if you keep that subscription to the newsletter open, you will get a new one every once and a while.

  1. Variable is deprecated as per RxSwift v4.x
  2. When something terminates unexpectedly in iOS, usually it is because it gets deallocated. If you are using DI such as Swinject, declare class containing your observable with container scope: 'container.register(MyClass.self) { _ in MyClass() }.inObjectScope(.container)'

SDL 2005: Model Driven: 12th International SDL Forum, Grimstad, , However termination is not always observable, as illustrated in fig. 11. In order to avoid unspecified signal reception in the transition between composed roles,  Ultimately, when it comes to getting fired, all you can do is own it. And when the subject comes up in your next job interview—and you know it will—you can make sure you’re prepared to address it honestly, while still framing yourself in the best possible light.

Programming Languages and Systems: 9th European Symposium on , 5.3 Termination as Observable After the preceding development, a natural we can prevent processes from even realising the presence of other processes, allowing us to type, say, (with M being a level between H and L), while eM do c : H  The advice here, from a seasoned employment lawyer, can prevent that from happening. What you don’t know about workplace rights can destroy your career or even get you fired.
