ListDiffable->diffIdentifier()，your implementation of this method may be wrong.

You should probably replace the data in your datasource instead of appending it, because if it's a refresh, it's probably expected to get the same ids, and then depending on the implementation of the diffIdentifier, you would also get the same identifiers, causing the "duplicate identifier" assertion.
