Hey, Apple team, any updates on that topic? Why does NSBatchInsertRequest do not provide any API for getting an internal context that is used for NSManagedObject creation: https://developer.apple.com/documentation/coredata/nsbatchinsertrequest/3618791-init It would be nice to have an access to NSManagedObject context here: managedObjectHandler handler: @escaping (NSManagedObject, NSManagedObjectContext) -> Bool So we could make add a relationship models just in place, without struggling with a workaround solutions.
