Nick Hutchinson's answer in Swift:

    let idDescription = NSExpressionDescription()
    idDescription.name = "objectID"
    idDescription.expression = NSExpression.expressionForEvaluatedObject()
    idDescription.expressionResultType = .objectIDAttributeType

I can't comment on it because I don't have enough rep :(
