Answer 1

It is just Typo mistake you might copy paste your code. You can easily find it by debug here is a small mistake you made

Observe here in struct Reviews

   if let customAttribute = dict["reviews"] as? [[String: Any]] {
        var result = [RatingVotes]()
        for obj in customAttribute {
            result.append(RatingVotes(dict: (obj as? [String : Any])!))
        }
        self.ratingVotes = result
    } else {
        self.ratingVotes = [RatingVotes]()
    }

You are using key reviews here dict["reviews"]

it should be rating_votes like dict["rating_votes"]

Hope it is helpful to you

Answer 2

You have getting both time review dictionary same value. if let customAttribute = dict["reviews"] as? [[String: Any] So change here 'review' to 'rating_votes'

Or follow below code may it help you!!

init(dict : [String:Any]) {
    if let customAttribute = dict["rating_votes"] as? [[String: Any]] {
        var result = [RatingVotes]()
        for obj in customAttribute {
            result.append(RatingVotes(dict: (obj as? [String : Any])!))
        }
        self.ratingVotes = result
    } else {
        self.ratingVotes = [RatingVotes]()
    }
    self.reviewId = dict["review_id"]
    self.createdAt = dict["created_at"]
    self.entityId = dict["entity_id"]
    self.entityValue = dict["entity_pk_value"]
    self.statusId = dict["status_id"]
    self.detailId = dict["detail_id"]
    self.title = dict["title"] as? String
    self.detail = dict["detail"] as? String
    self.nickName = dict["nickname"] as? String
    self.customerId = dict["customer_id"]
    self.entityCode = dict["entity_code"]
 }
}
