NSKeyedArchiver
NSKeyedArchiver is a component of Apple's Foundation framework that provides a keyed archiving mechanism for encoding and decoding objects that implement the NSCoding protocol. It is used to convert an object graph into a data representation suitable for persistence, transmission, or storage, and to reconstruct the original objects from that representation.
Objects intended for archiving must implement NSCoding by providing methods to encode and initialize themselves from
Modern usage favors data-based archiving over file-based roots. Archiving and unarchiving are typically performed with the
Security considerations include support for NSSecureCoding. Classes should adopt NSSecureCoding and implement supportsSecureCoding to ensure that
