// When you’re downloading objects from the web, it’s common to need to merge changes
// from the server to already-existing local objects. (If your data model allows for
// mutable objects, as with Core Data, that is.)
//
// The below is a Swift translation of how I’ve done this in Objective-C.
// Note that it works just fine in Swift — though it does require NSObject subclasses.
