are needsDisplayForKey/actionForKey overrides working correctly?

Question

I\'m trying to convert some code that works in Objective-C to Swift. The problem I\'m running into is that needsDisplayForKey/actionForKey aren\'t getting called the same way.

Answer 1

I got this working in Swift by using @NSManaged attribute in front of the variable declaration (where you would use the the @dynamic attribute in Objective-C)
