Does keeping a reference to Observer cause a retain-cycle? about rxcoredata HOT 2 CLOSED

No, in this case there is no retain cycle.

Observable.create { observer in
			
			let observerAdapter = FetchedResultsControllerEntityObserver(observer: observer, fetchRequest: fetchRequest, managedObjectContext: self.base, sectionNameKeyPath: sectionNameKeyPath, cacheName: cacheName)
			
			return Disposables.create {
				observerAdapter.dispose()
			}
        }

Observer is retained by Observable and FetchedResultsControllerEntityObserver
FetchedResultsControllerEntityObserver is retained by Observable, it has a reference in Disposable
As soon as Observable will be deallocated, FetchedResultsControllerEntityObserver will have no other reference which will release it. Then Observer will be released as well.

Oh, so the Observable owns the Observer. And FetchedResultsControllerEntityObserver is also owned by the Observable, so it's all down stream and will be deallocated with Observable. That makes a lot of sense. Thank you for your explanation.
