viewcontroller conform to protocol "UITableViewDataSource, Video Mode Delegate"? - ios

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

It looks as though you haven't closed the method didReceivedMemoryWarning: and the tableview delegate methods are then effectively inside this method causing your issue. Add a closing bracket and it should be fine:
Update: Here is the updated code. There was some more formatting issues with brackets and an error with your if statement in the cellForRowAtIndex:
