Hi Davide!

Thank you so much for the feedback. I also ran into a similar problem when using it for testing. In my case, I had a bug where the publisher never emitted a value neither was completed. This caused the test to run forever. I believe the solution I had was very similar to yours, the only difference is that I had to put a timeout as well. I'd love to update the article with your solution giving you the credits! Do you think this code snippet represents your solution and/or fixes it?

extension AnyPublisher {

func async(timeout: RunLoop.SchedulerTimeType.Stride = .seconds(1)) async throws -> Output {

try await withCheckedThrowingContinuation { continuation in

var cancellable: AnyCancellable?

var finishedWithoutValue = true

cancellable = first()

.timeout(timeout, scheduler: RunLoop.main)

.sink { result in

switch result {

case .finished:

if finishedWithoutValue {

continuation.resume(throwing: AsyncError.finishedWithoutValue)

}

case let .failure(error):

continuation.resume(throwing: error)

}

cancellable?.cancel()

} receiveValue: { value in

finishedWithoutValue = false

continuation.resume(with: .success(value))

}

}

}

}
