The following code does not work

class Hero : AnyObject, NSCoding {

    var heroID: String?
    var title: String?
    var imageName: String?
    var detail: String?
    var star: String?

    init() {

    }


    func update(_ dictionary: Dictionary) {

        heroID = dictionary["imageName"] as? String
        title = dictionary["title"] as? String
        imageName = dictionary["imageName"] as? String
        detail = dictionary["detail"] as? String
        star = dictionary["star"] as? String

    }
    required init?(coder aDecoder: NSCoder) {
        heroID = aDecoder.decodeObject(forKey: "heroID") as? String
        title = aDecoder.decodeObject(forKey: "title") as? String
        imageName = aDecoder.decodeObject(forKey: "imageName") as? String
        detail = aDecoder.decodeObject(forKey: "detail") as? String
        star = aDecoder.decodeObject(forKey: "star") as? String
    }

    func encode(with aCoder: NSCoder) {
        aCoder.encode(heroID, forKey: "heroID")
        aCoder.encode(title, forKey: "title")
        aCoder.encode(imageName, forKey: "imageName")
        aCoder.encode(detail, forKey: "detail")
        aCoder.encode(star, forKey: "star")
    }
}

Be sure to write like this

class Hero : NSObject, NSCoding {

    var heroID: String?
    var title: String?
    var imageName: String?
    var detail: String?
    var star: String?

    override init() {

    }
}
