Books / Videos / Ressources to dive deep into Core Data?

My boss gave me the big mission to become an Core Data nerd. He wants me to spend at l开发者_StackOverflow社区east 4 months fulltime on this topic, so that I can help with any problem that arises. Damn.

Ok... I assume you have lots of great links for me! Let me suck them into my brain like a vacuum cleaner.

Videos, Books, Ressources, etc... he gave me $500 budget for buying books and trainings! So just recommend anything you think is good, and I'll drain his pockets empty.

Been there, done that...
