Flatiron School Week 4- Questions and Answers

Topics: Cocoapods and Core Data

Question: Should I use [array mutablecopy] or [NSMutableArray arrayFromArray:array]  ?

Answer: Both are the same if the array is already made. Stylistically, prefer the latter.

Question: Is order maintained in Core Data?

Answer: No, if you want to maintain order, add an attribute like createdAt and use an NSSortDescriptor to order by created time.
