[Additional Errors][Error]1How to make my viewcontroller conform to protocol "UITableViewDataSource, and Video Mode Delegate"?

I have tried a number of suggested changes in the previous threads, but nothing got me through, Please help me out.

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:

import UIKit
import Alamofire


class tab: UIViewController, UITableViewDataSource, UITableViewDelegate, VideoModelDelegate { 

    @IBOutlet weak var table: UITableView!
    @IBOutlet weak var name: UILabel!

    var videos : [Video] = [Video]()
    var selectedVideo:Video?
    let model:VideoModel = VideoModel()
    var arrRes = [[String:AnyObject]]() //Array of dictionary

    override func viewDidLoad() {
        super.viewDidLoad()


        self.model.delegate = self
        //self.videos = model.getVideos()

        model.getFeedVideos()


        self.table.dataSource = self
        self.table.delegate = self


        /*Alamofire.request(.GET, "http://online.m-tutor.com/mtutor/gateway/mtutorAPI_1.php?type=university").response { (req, res, data, error) -> Void in

            let outputString = NSString(data: data!, encoding:NSUTF8StringEncoding)
            print(outputString)
        }


        Alamofire.request(.GET, "http://online.m-tutor.com/mtutor/gateway/mtutorAPI_1.php?type=university").responseJSON { response in
            if let swiftyJsonVar = response.data

  • Sir, I made the changes, but still the error exists. The Xcode is suggesting me these changes for this line "let videoThumbnailUrl != nil "(Suggestions:1- Unary operator cannot be separated from its operand, 2- Consecutive statements on line should be separated by ';') and other error do remain as if the same. Kindly help me... – Manee ios Mar 24 '16 at 10:21
  • Just spotted some more syntax issues, check comments in update. – Joe Benton Mar 24 '16 at 10:26
  • Sir the error count has reduced, as of now I am getting these two errors if let videoThumbnailUrl = videos[indexPath.row].videoThumbnailUrlString {(ERROR- Value of type 'video' has no member ' videoThumbnailUrlString' ) and the other ERROR is "Type 'tab' does not conform to protocol 'UITableViewDataSource'" – Manee ios Mar 24 '16 at 10:32
  • What are the two errors. (sorry I dont have xCode at the minute to test, just doing this from reading your code snippets) – Joe Benton Mar 24 '16 at 10:40
  • 1) Value of type 'video' has no member ' UITableViewDataSource' 2) Type 'tab' does not conform to protocol 'UITableViewDataSource – Manee ios Mar 24 '16 at 10:42
  • That first issue is whatever you have called it in your video model? Maybe check incase videoThumbnailUrlString should be something else? – Joe Benton Mar 24 '16 at 10:47
  • Dear Joe I have attached the videomodel code above, please have a look – Manee ios Mar 24 '16 at 10:54
