    This is not the exact response to your question, but a problem people might now encouter with your code now:

    In the latest version of XCode, you must now unwrap the predicate, like this:

    var compound = NSCompoundPredicate.andPredicateWithSubpredicates([predicate1!, predicate2!])
    

    because NSPredicate initializer now return NSPredicate? type.
