Okay i'm pretty new to all of this but right now I'm trying to wrap my head around core data. Right now I'm just trying to make a simple drill down type app using core data as the DB So I have an entity called Apartments with two attributes "number" "timeStamp" and a one-to-many relationship called checklist with the cascading delete rule. Then I have another entity called "Checklist" with attributes like "name" "timeStamp" etc. Basically how do I list the Checklists under a specific Apartment in my view controller? This has something to do with the fetchrequest right? I've seen dot notation used in the fetchrequest key is that what it's for?
