Description: NSKeyedUnarchiver is a class from Apple’s development platform that provides methods for unarchiving objects that have been previously archived. This class is part of the Foundation framework and is primarily used in application development across various platforms. Its main function is to convert serialized data back into class objects, allowing for the retrieval of information stored persistently. NSKeyedUnarchiver works in conjunction with NSKeyedArchiver, which is the class responsible for archiving objects. The serialization and deserialization of objects is fundamental in application development, as it allows for the saving of object states and their later retrieval, facilitating data management in applications that require persistence, such as databases or disk storage. NSKeyedUnarchiver supports the encoding of complex objects, including those that contain references to other objects, making it a powerful tool for data management in modern applications. Additionally, this class allows for the implementation of custom encoding, meaning developers can define how their own objects should be archived and unarchived, providing flexibility and control over the serialization process.
