How does one choose which Core Data record to fetch?
I have one entity, “Credit Card”, and I have ten actual credit cards stored in that entity. How do I say “Hey, I want to fetch THAT card?”

You create an NSFetchRequest with a predicate that identifies the credit card you want (e.g.,
id = 3orcardHolderName = "JOE SMITH"), then ask the NSManagedObjectContext to execute the fetch request, returning the result set (which will contain the one card you want).
