Threads

Information¶

Important difference between how to handle threads while subscribing or working with the UI in RxSwift

Check thread type¶

Use default Thread.isMainThread in the subscribe block in order to identify whether the thread is Main thread or background thread.

Observable<Int>.create { observer in
    observer.onNext(1)
 return Disposables.create()
}
.subscribe(onNext: { el in
    print(Thread.isMainThread)
})
