How to define CoreData relationship in Swift?

Question

In CoreData, I have defined an unordered to-many relationship from Node to Tag. I\'ve created an Swift entity like this:

import Cor

Building on @Keenle's answer, if you want to be cheeky and concise and be able to say

node.tags.append(tag)

one can wrap the call to self.mutableSetValueForKey:

class Node: NSManagedObject {

    var tags: NSMutableOrderedSet {
        return self.mutableOrderedSetValueForKey("tags")
    }
}
