For your NSKeyedArchiver.archivedData(withRootObject: value) to work, your Order needs to conform to the Codable protocol. Just add these in your Order struct to this and it should work just fine.

required public init(coder decoder: NSCoder) {

    item_id = decoder.decodeObject(forKey: "item_id") as? String ?? ""
    quantity = decoder.decodeObject(forKey: "quantity") as? Int ?? 0
    image = decoder.decodeObject(forKey: "image") as? String ?? ""
    name = decoder.decodeObject(forKey: "name") as? String ?? ""
    desc = decoder.decodeObject(forKey: "desc") as? String ?? ""

}

public func encode(with coder: NSCoder) {

    coder.encode(item_id, forKey: "item_id")
    coder.encode(quantity, forKey: "quantity")
    coder.encode(image, forKey: "image")
    coder.encode(name, forKey: "name")
    coder.encode(desc, forKey: "desc")
}
