Handle unrelated serial api calls in RxSwift

Question

I have a requirement to get responses from multiple requests with different models in RxSwift. I want to do this without GCD or Semaphore and only with RxSwift. I try this code but have some problems with in different responses with different models and counts of results objects.

 Observable.zip(service.fetchAlbums(), service.fetchUsers())
.subscribe(onNext: { (albums, users) in
        print(albums)
        print(users)
    })
    .disposed(by: self.disposeBag)

What are the problems you are having? – Daniel T. Sep 11 '22 at 11:15 — Daniel T., Sep 11 '22 at 11:15

The following works fine.

import RxSwift

func example(service: Service, disposeBag: DisposeBag) {
    Observable.zip(service.fetchAlbums(), service.fetchUsers())
        .subscribe(onNext: { (albums, users) in
            print(albums)
            print(users)
        })
        .disposed(by: disposeBag)
}

protocol Service {
    func fetchAlbums() -> Observable<[Album]>
    func fetchUsers() -> Observable<[User]>
}

struct Album { }
struct User { }
