RxSwift vs Combine

PublishSubject.swift

let subject = PublishSubject<String>()

subject.onNext("Is anyone listening?")


let subcription1 = subject.subscribe { event in
    print("1) \(event)")
}

let subcription2 = subject.subscribe { event in
    print("2) \(event)")
}

subject.onNext("Hello")
subject.onCompleted()
subject.onNext("Is alive?")

<Output>
1) next(Hello)
2) next(Hello)
1) completed
2) completed
