Hi Zeeshan,

Thanks for your feedback.

This command matches RxSwift version 5 (where the first input type, RxTimeInterval, is a type-alias of DispatchTimeInterval and not of TimeInterval). It seems your RxSwift framework is outdated.

Try using:

_ = Observable<Int>.interval(1, scheduler: MainScheduler.instance)
    .subscribe(onNext: { _ in
    print(“Rx Resource Count: \(RxSwift.Resources.total)”)
})
