Answer 1

You have a custom class Furniture which you are trying to archive with NSKeyedArchiver. In order for this to work, the Furniture class needs to conform to the < NSCoding > protocol. Which means implementing the encodeWithCoder: and initWithCoder: methods.

Currently you don't implement these methods. You need to add them.
