syncContextDidSave calling notifyAboutChangedObjectsFromSaveNotification

[bluk]

In https://github.com/objcio/core-data/blob/master/Moody/MoodySync/SyncContextOwner.swift#L65 , does anyone know why the notifyAboutChangedObjectsFromSaveNotification is called?

The sync context is saved and then the changes are merged into the main managed object context in the ContextOwnerType's syncContextDidSave function. It seems that since the changes are coming from the sync context, that we shouldn't have to basically call performLocalChanges in notifyAboutChangedObjectsFromSaveNotification.

Thanks for any help anyone can provide!

@bluk There is a small section in the book explaining how to handle ordering between changeProcessors. So, basically if one of your changeProcessors needs to process objects only after they have been processed by another changeProcessor, you can adjust the predicate so that the objects will satisfy the predicate only after being processed by the first changeProcessor (for example, if you changeProcessor needs to work only with the uploaded objects, your predicate should contain remoteID != NULL). Once the first changeProcessor processes the objects, it will then set some of the fields of these objects on the syncContext, and because of the performLocalChanges these changed objects will be picked and processed by the second changeProcessor immediately, and not after another trigger of the synchronization.
