RxSwift-Subjectとの違いを観測できる

観測可能またはSubjectの違い

Subject

//SubjectType에서 ObservableType을 채택
public protocol SubjectType : ObservableType {
    
    associatedtype Observer: ObserverType

    /// Returns observer interface for subject.
    ///
    /// - returns: Observer interface for subject.
    func asObserver() -> Observer
}

の観測対象とSubjectと区別があるとすればUnicastですが、マルチキャストです.

UniCast or MultiCast

let randomWithIntObservable: Observable<Int> = Observable<Int>.create { observer in
    observer.onNext(Int.random(in: 1...100))
    
    return Disposables.create()
}

randomWithIntObservable.subscribe { event in
    print("randomWithInt :(1) \(event)")
}


randomWithIntObservable.subscribe { event in
    print("randomWithInt :(2) \(event)")
}

let randomWithSubject: PublishSubject<Int> = PublishSubject<Int>()


randomWithSubject.subscribe { event in
    print("randomWithIntSubject :(1) \(event)")
}

randomWithSubject.subscribe { event in
    print("radomWithIntSubject :(2) \(event)")
}

randomWithSubject.onNext(Int.random(in: 1...100))
