This is proving very hard to diagnose, as it doesn't always happen. I tried observing -managedObjectContext, but it never gets called with a nil value. Moreover, my entity's -dealloc method is sometimes called even though none of the -awake methods gets called. This is a complex app with a lot of async operation, so this entity gets created and destroyed often, making it that much harder to figure out exactly what's going on.
I can bulletproof the place where the crash occurs when the moc is nil, but I'd really like to track down the underlying problem. > On Mar 27, 2019, at 12:17 , Mike Abdullah <mabdul...@karelia.com> wrote: > > Given the number of objects Core Data is designed to juggle, managing that > number of weak references might well affect performance.
