Describe the feature request

Enhance PollerError with associated value Error, i.e. PollerError.noResponse(Error?).

Background

In Poller.swift: line 129, the function getFeatures(context:completionHandler:) -> Void completes with noResponse error.

guard let httpResponse = response as? HTTPURLResponse else {
    Printer.printMessage("No response")
    completionHandler?(.noResponse)
    return
}

Our iOS project has to catch the exact error from the session to do some other requests, especially for the noResponse error.

Solution suggestions

Providing detailed error in associated values on PollerError. And pass them from getFeatures(context:completionHandler:) -> Void of Poller.swift.

public enum PollerError: Error {
    case decoding(Error)
    case network(Error?)
    case url
    case noResponse(Error?)
    case unhandledStatusCode(Int)
}
