…how were you triggering UI updates from model changes? KVO? NSFetchedResultsController? Core Data change notifications?

A DataStorage object vended signals by filtering the Core Data notifications.

Interesting. The case that seems hardest is when things would fall into/out of fetched sets. Were you solving for that?

DataChangeEvent<T> is the signal's value type.

so would, say, a table data source get ALL such signals, and check each against its fetch criteria?

No, DataStorage defines eg func findTopicsInDomain(domain) -> Signal
