The Retry publisher retries an upstream publisher when a given condition is met. You can pass a publisher to run before retrying.
upstreamPublisher.retry { value in
return indicatesFailure(value)
}Restarts the upstream publisher if the value it sent indicates failure. Failures will just be propagated downstream.
apiCallPublisher.retry(butFirst: authenticatePublisher) { response in
return response.statusCode == 401
}Restarts the API call publisher if the response indicates being unauthorized, but will first authenticate using the authenticate publisher.
