viewcontroller соответствует протоколу «UITableViewDataSource, Video Mode Delegate»?

Question

import UIKit 
import Alamofire 

protocol VideoModelDelegate{ 
func dataReady() 
} 

class VideoModel: NSObject { 

let API_KEY = "" 
let UPLOADS_PLAYLIST_ID = "" 


var videoArray = [Video]() 

var delegate:VideoModelDelegate? 

func getFeedVideos() -> [Video] { 

     Alamofire.request(.GET, "",parameters: ["part":"snippet",   "playlistId":UPLOADS_PLAYLIST_ID ,"key":API_KEY], 
encoding: ParameterEncoding.URL, headers: nil).responseJSON {(response) -> Void in 

     if let JSON = response.result.value{ 

      var arrayOfVideos = [Video]() 

      for video in JSON["items"] as! NSArray { 
       print(video) 
       let videoObj = Video() 
     videoObj.videoId = video.valueForKeyPath("snippet,resourceId,  videoId") 
       String 
     videoObj.videoTitle = video.valueForKeyPath("snippet.title") as! String 
     videoObj.videoDescription = video.valueForKeyPath("snippet.description") as! 
       String 
       videoObj.videoThumbnailUrl = video.valueForKeyPath("snippet.thumbnails.maxres.url") as! String 
       arrayOfVideos.append(videoObj) 
     } 

      self.videoArray = arrayOfVideos 

      if self.delegate != nil { 
       self.delegate!.dataReady() 

      } 

     } 
    } 
     } 
    func getVideos() -> [Video] { 
    var videos = [Video]() 

    let video1 = Video() 

    video1.videoId = "" 
    video1.videoTitle = "" 

    videos.append(video1) 

    return videos 

} 

}

[Дополнительные ошибки] [Ошибка] 1 Как сделать мой ViewController соответствовать протоколу "UITableViewDataSource и ВИДЕОРЕЖИМЕ делегат"?

Я пробовал ряд предлагаемых изменений в предыдущих потоках, но ничего не дошло, пожалуйста, помогите мне.

Заранее спасибо

Это выглядит так, как будто вы не закрыли метод didReceivedMemoryWarning: и методы TableView делегат затем эффективно внутри этого метода вызывает проблему. Добавьте закрывающий кронштейн, и все должно быть хорошо:

Обновление: Вот обновленный код. Был еще некоторые проблемы с форматированием скобками и ошибка с вашей, если заявление в cellForRowAtIndex:
