how to use Moya RxSwift to get an array of REST merged

Question

I am trying to learn RxSwift. I had been using Moya and now want to try my hand at RxSwift. Totally confused.

 let popServiceProvider = MoyaProvider<PopRESTService>()
    let o1 = popServiceProvider.rx.request(.getPopByCity(city: "London")).asObservable()
    let o2 = popServiceProvider.rx.request(.getPopByCity(city: "Tokyo")).asObservable()

    let pObservables:[Observable<Response>] = [o1, o2]
    let stats: Observable<Response> = Observable.combineLatest(pObservables)
    let m = stats.map({ a in
        print(a)
    })  

First I get an error on let stats:

Cannot convert value of type 'Observable<[Response]>' to specified type 'Observable'

am I even going in the right direction?

EDIT:

Even this doesn't work. Never first the subscribe:

   wServiceProvider.rx.request(.getWeatherByCity(city: "Chicago"))
    .debug()
    .map(Weather.self)
    .subscribe({ (event) in
        switch event {
        case let .success(response):
            print(response)

        case let .error(response):
            print(response)
        }
    })
    .disposed(by: self.disposeBag)

My misunderstanding of Apple XCTest. I needed to add:

                expectation.fulfill()

in my subscribe.

Observable.combineLatest([o1, o2])
        .map { (responses: [Response]) -> [Weather] in
            responses.map { try? JSONDecoder().decode(Weather.self, from: $0.data) }
                .compactMap { $0 }
        }
        .debug()
        .subscribe(onNext: { (result: [Weather]) in
            print(result)
            expectation.fulfill()

        })
        .disposed(by: disposeBag)
