what are fetched properties? How do you create a fetched property?

Answer Posted / Deep Ranjan Tiwari

"Fetched properties" are properties that return an array of managed objects based on a predicate. They allow you to perform complex queries without having to write custom fetch requests. To create a fetched property, define it in the entity definition file and set the attribute type to transformable or NSManagedObjectIDArrayType. The predicate is defined as the formula in the fetched property declaration.
