jsonを複数の値で解析するにはどうすればよいですか？

Question

私のコードにJSONファイルを解析しようとしています。 これまでのところ、値の配列を持つ1つのキー（ジャンル）を除いて、私はそうすることができました。 私はUILabelにそれを提示することができますので、私はそれを解析する方法を知りたいですか？ファイル内

Movieクラス：

import UIKit 
class Movie { 
    var title = "" 
    var image = "" 
    var rating = 0.0 
    var releaseYear = 0 

    init(object: [String: AnyObject]) { 
     self.title = object["title"] as! String 
     self.image = object["image"] as! String 
     self.rating = object["rating"] as! Double 
     self.releaseYear = object["releaseYear"] as! Int 


    } 

    init() { 

    } 
} 

MovieCellクラス：

import UIKit 
import SDWebImage 

class MovieCell: UITableViewCell { 


    @IBOutlet weak var titleLbl: UILabel! 
    @IBOutlet weak var releaseYearLbl: UILabel! 
    @IBOutlet weak var ratingLbl: UILabel! 
    @IBOutlet weak var movieImage: UIImageView! 
    @IBOutlet weak var genreLbl: UILabel! 

    override func awakeFromNib() { 
     super.awakeFromNib() 

    } 

    func createCell(movie: Movie) { 
     self.titleLbl.text = movie.title 
     self.releaseYearLbl.text = "\(movie.releaseYear)" 
     self.ratingLbl.text = "\(movie.rating) ⭐️" 

     movieImage.layer.cornerRadius = 10.0 
     movieImage.clipsToBounds = true 

     self.movieImage.sd_setImage(with: URL(string: movie.image)) 

    } 

    override func setSelected(_ selected: Bool, animated: Bool) { 
     super.setSelected(selected, animated: animated) 

     // Configure the view for the selected state 
    }

ただ、コードの下に分析し、問題に適用

Movieクラスになる

、のUITableView

グローバル変数を持っていた

class Movie { 

    var title = "" 
    var image = "" 
    var rating = 0.0 
    var releaseYear = 0 
    var genre:String? 

    init(object: [String: AnyObject]) { 
     self.title = object["title"] as! String 
     self.image = object["image"] as! String 
     self.rating = object["rating"] as! Double 
     self.releaseYear = object["releaseYear"] as! Int 
     let genreArray = object["genre"] as! [String] 

     /*Whatever you want do here with genre. I thought you need whole array to one readable String*/ 
     for strings in genreArray{ 

      self.genre = self.genre == nil ? strings : self.genre!+" "+strings 
     } 

    } 
} 

クラスクラスは、

です

var movieData = Array<Movie>() 

JSONの解析が意志となり、

if let json = try! JSONSerialization.jsonObject(with: data, options: .allowFragments) as? Array<Dictionary<String, AnyObject>>{ 

for object in json{ 

    self.movieData.append(Movie(object: object)) 
} 

DispatchQueue.main.async { 
    self.tableView.reloadData() 
} 

UITableView datasource

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 

    return movieData.count 
} 

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 

    let cell = self.tableView.dequeueReusableCell(withIdentifier: "cell", for:indexPath) 

    let tableObject:Movie = self.movieData[indexPath.row] 
    cell.textLabel?.text = tableObject.genre //This way you will be get all values and apply it to whatever you want... 
    return cell 
} 

OUTPUT： -
