From Apple Documentation
The NSPrivateQueueConcurrencyType configuration creates its own queue upon initialization and can be used only on that queue. Because the queue is private and internal to the NSManagedObjectContext instance, it can only be accessed through the performBlock: and the performBlockAndWait: methods.
Why you are not using these two methods in your code?
Dataset I used has 100,000 json records with two words per record. Size was ~8MB. This causes the app to crashe each time at persistenceManager.mergeWithMainContext.
After deleting objects (Events in your case), then closing and restarting the application, the objects that I deleted still show up. I was wondering if I was doing something wrong, since I am deleting my objects just as you are deleting your Event objects.
Datasets get persisted redundantly. When deleting the redundant batch that is persisted the app crashes.
Steps to reproduce:
The offending class:
EventTableViewController.swift
The offending line:
Line 121 eventList.remove(at: (indexPath as NSIndexPath).row)
