The canonical way to save an NSDictionary into CoreData is with NSValueTransformers.

I don't know if it works with CFDictionaries however. There is no mention of it working or not. With toll free bridging however it sure seems like it should work.

If it were me, I'd try using the value transformer. If that doesn't work, you can easily convert the CFDictionaryRef into an NSDictionary with:

NSDictionary *dictionaryObject = [NSDictionary dictionaryWithDictionary:(NSDictionary *)dictionaryRef];

You cannot save dictionaries to CoreData.
You could however try to convert it to a NSData first and convert it back to a dictionary when before using it. See this post.
