How Smart (Or Dumb?) Should NSManagedObjects Be?

Read Original

This article discusses the design philosophy behind NSManagedObject subclasses in Core Data, advising developers to keep them focused on Core Data-related functionality. It covers overrideable lifecycle methods like awakeFromFetch, awakeFromInsert, willSave, and didSave, as well as custom validation logic and key-value observing. The key takeaway is to let Core Data needs guide subclass extensions, avoiding unnecessary complexity.
