Yes, it kinda really acts like @dynamic — technically it might be identical even. Semantically there is a slight difference:
@dynamic says ‘compiler, don’t check if my properties are also implemented. There might be no code you can see but I guarantee it will work at runtime’
@NSManaged now says ‘compiler, don’t check those properties as I have Core Data to take care of the implementation – it will be there at runtime’
so you could even say: @NSManaged is syntactic sugar that is a more narrow version of dynamic 🙂

here someone even used @NSManaged without CD because he wanted the @dynamic behaviour
