Answer 1

var movies: [NSDictionary]? 
var dates: NSDictionary? 

var page: Int? // var for page 
var maximum: String? // var for maximum in dates 

func fetchNowPlayingMovies(){ 
    let apiKey = "8e3967947a95555f9c430e68d070a0e7" 
    let url = URL(string: "https://api.themoviedb.org/3/movie/now_playing?api_key=\(apiKey)"+"&language=en-US&page=1") 
    let request = URLRequest(url: url! as URL, cachePolicy: URLRequest.CachePolicy.reloadIgnoringCacheData, timeoutInterval: 10) 
    let session = URLSession(configuration: URLSessionConfiguration.default, delegate: nil, delegateQueue: OperationQueue.main) 
    let task: URLSessionDataTask = session.dataTask(with:request, completionHandler: {(dataOrNil, reponse, error) in 
     if let data = dataOrNil{ 
      if let responseDictionary = try! JSONSerialization.jsonObject(with: data, options: []) as? NSDictionary { 
       //print("reponse: \(responseDictionary)") 
       self.movies = responseDictionary["results"] as? [NSDictionary] 
       self.dates = responseDictionary["dates"] as? NSDictionary 

       // This is how you get to page 
       print("page: \(responseDictionary["page"]!)") 
       self.page = responseDictionary["page"] as? Int 
       print("page: \(self.page!)") 

       // This is how you get to maximum in dates 
       self.maximum = self.dates?["maximum"] as? String 
       print("maximum: \(self.maximum!)") 

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

Ich hoffe, es
