Crash because of NSMutableOrderedSet

[dehlen]

Hello,

When using this library I get the following error message:
Could not cast value of type '_NSFaultingMutableOrderedSet' (0x19fe9c2e8) to 'NSSet' (0x19fe879e8).
It occurs in SMStore.swift - setRelationshipValuesForBackingObject: because of this line:

let relationshipValue: Set<NSObject> = sourceObject.valueForKey(relationship.name) as! Set<NSObject>

I can't find my mistake since I already got the inverse relations set up as you are describing in the README. I hope you can give me a hint why this does not work.

Here is my xcdatamodeld setup :

The error indicates that the OrderedSet can not be casted to a regular Set.

Depending on how relationshipValue is used you either can use an iterative protocol that both Set and OrderedSet implement. Or you need to have different ways to use relationshipValue

By "you" I mean Seams SMStore.swift that you could fix.
