How can I decode an object when original class is not available?

Question

I have an iOS 7 application that saves a custom object to app\'s iCloud Docs folder as a file. For this, I make use of NSCoding protocol.

@interface Person : NSO

If the name of the class in Objective-C is important, you need to explicitly specify the name. Otherwise, Swift will provide some mangled name.

@objc(Person)
class PersonOldVersion: NSObject, NSCoding {
    var name = ""
    var lastName = ""
}
