Trick, how to add a generic function available for each NSManagedObject subclass
View Extension for all NSManagedObject Subclass
 extension NSObjectProtocol where Self: NSManagedObject { static func findAllWithPredicate(searchTerm: NSPredicate?, inContext context: NSManagedObjectContext = NSManagedObjectContext.MR_defaultContext()) -> [Self] { //You can implement the fetchrequest here by yourself, but now I'm using MagicalRecord service to keep it simple return self.MR_findAllWithPredicate(searchTerm, inContext: context) as! [Self] } } Usage (There is no cast required here, but the result is a [AnswerObject]):
