The example used in the video is an update of the project used last year to explain the batch functions. in that project NSBatchInsertRequest is used to insert large data in few seconds but NSBatchInsertRequest could not be used to set the relationships. I don't understand if this is changed or not, but, if not, can I use the concurrency to set the relationship? is it possible to have an simple example in which you can save large data with relationship in few seconds?
