How to know subscription state about apollo-ios HOT 1 OPEN

Hi @arnauddorgans - there unfortunately isn't any way to get the status of a single subscription.

The current implementation is very naive with regards to it's implementation of subscribers. There is a list of subscribers keyed by an identifier with no state being stored about the subscriptions. I suppose if a subscriber identifier is in that list it could be considered 'open' but for identifiers that are not present we'd have no idea if that had even a valid identifier so it would be incorrect to return 'closed' when it could have been 'never existed'.

There is probably a hacky solution we could implement to enable this for now but 2.0 is really where we'll improve everything networking.

WebSocketTransportDelegate will give you connection events for WebSocketTransport so you could use this as a sort of proxy indicator if you only have a single subscription, but if you use the same websocket transport for multiple subscriptions then that will not work.
