@drewmccormack Why it's not a great post: http://blog.metaobject.com/2013/10/should-you-use-coredata.html …

@mpweiher @drewmccormack For evidence, you can look at what Apple does vs says. Are Mail, Aperture, Contacts sync, etc. all “corner cases”?

@mjtsai Not really. Some teams in Apple are surprisingly ignorant of Apple's own tech. What do they use instead? XML? Rest my case.

@drewmccormack Article says that you should use Core Data because Apple uses it for apps, and Apple knows best. But where are said apps?

@mjtsai Quick scan shows Calendar, Contacts, Notes, iBooks. More important, 3rd party apps Pixelmator, Tokens, Transmit, Yojimbo.

@drewmccormack Notes and iBooks don’t use it for syncing, either. Nor for storing large amounts of data. No iWork or iLife apps (AFAIK).

@mjtsai Won't argue with you on iCloud sync: it's rubbish. iWork etc are pretty old. Think it is all still XML.
