RxSwift TestScheduler for two sources

Question

I would like to emit two different signals for two different sources, but I get crash Thread 1: EXC_BAD_ACCESS (code=1, address=0x0) in RxSwift/Event.swift in line 29: return "next(\(value))"

this is my simplified code:

        let scheduler = TestScheduler(initialClock: 0)

        locationsFactory = TestableLocationsFactory()
        locationsFactory.didReceiveRegion = scheduler.createColdObservable([
        .next(100, regionEvents[0]),
        .next(200, regionEvents[1])
        ]).asObservable()

        locationsFactory.location = scheduler.createColdObservable([
        .next(120, locations[0]),
        .next(220, locations[1])
        ]).asObservable()

        let result = scheduler.createObserver(LocationChange.self)
        let dispatcher = BestAccuracyLocationsDispatcher(persistenceService: persistenceService, apiClient: api, locationManager: locationsFactory)

        subscription = dispatcher.dispatcher.subscribe(result)
        scheduler.start()

        let events = result.events

        XCTAssertEqual(events, [
            .next(120, LocationChange(location: locations[0], trigger: .updateLocations)),
            .next(220, LocationChange(location: locations[1], trigger: .updateLocations)),
        ])

When I remove locationsFactory.didReceiveRegion or locationsFactory.location it works.

Can I create two different scheduler's observables?

Answer 1

I used mock of region let region = CLRegion() which is an abstract class. It started to work when I changed it to:

let region = CLCircularRegion(center: CLLocationCoordinate2D(latitude: 5.555, longitude: 6.666), radius: Double(50), identifier: "xxx")
