Hey @ALL,
I've a in-memory shared user in my app.
When I subscribe to changes within a Task to it I do not receive the changes:
Task { for await user in $user.publisher.values { print(user) } }
This prints only the initial value but not the changes. The task never finishes nor does it get cancelled as far as I know.
When I subscribe to the changes via Combine it works:
cancellable = $user.publisher.sink { user in print(user) }
What am I doing wrong?

Hi @ALL. It was my own dumbness. I had a guard statement within the for await loop and in its else block I had a return statement which canceled the loop. 🫣

In-memory keys don't implement any kind of subscribing whatsoever currently: https://github.com/pointfreeco/swift-sharing/blob/main/Sources/Sharing/SharedKeys/InMemoryKey.swift#L56-L60
I suppose it would be a welcome addition to the library in a PR?

Wild guess, have you checked you don't accidentally overwrite _user (mind the underscore, as opposed to $user) with another Shared<...>? That appears to be a trap for some.

@pyrtsa that subscription is left empty because there is no external storage system that needs to be subscribed to. But that shouldn’t affect how the publisher works.
