It actually fetches, but you have to downcast it to nsobject and get values using valueforkey . If you have your like.event , like.event.name will crash, however like.event.valueForKey("name") will work. So basically it works , but it's not very convenient.
No, it didn't, still can only store but not fetch relational data.
If I fetch with KCSLinkedAppdataStore a Like , the corresponding event is not resolved , however property "toUser" is being resolved.
