What does @NSManaged do?

Question

I have encountered this keyword in various occasions. I kind of know what it\'s suppose to do. But I really want a better understanding of it.

What I noticed about

Answer 1

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
