expected identifier for type name

The below code is giving me the error:

expected identifier for type name

Maybe it could be the reason that I should handle with it with self, because I saw some post. but it didn't work.

What kind of identifier Xcode talks about me? And how can I fix it?

If I fixed this error, but there are more errors, should I work with a UITableViewController rather than a separate UIViewController and UITableViewDelegate?

import UIKit
import Parse

class Home: UIViewController, UITableViewDelegate,  {  //error here "expected identifier for type name"


    @IBOutlet weak var homepageTableView: UITableView!
    var imageFiles = [PFFile]()
    var imageText = [String]()

    override func viewDidLoad() {
        super.viewDidLoad()

        var query = PFQuery(className: "Posts")
        query.orderByAscending("createdAt")
        query.findObjectsInBackgroundWithBlock { ( posts : [AnyObject]?, error : NSError?) -> Void in
            if error == nil {
                //불러오는데 성공
                for posts in posts! {
                    self.imageFiles.append(posts["imageFile"] as! PFFile)
                    self.imageText.append(posts["imageText"] as! String)
                    println(self.imageFiles.count)
                }

                /**reload the table **/
                self.homepageTableView.reloadData()
                println("reloaded")
            } else {
                println(error)
            }
        }
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return imageFiles.count
    }

    func tableView(tableView:  UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell : TableViewCell = tableView.dequeueReusableCellWithIdentifier("Cell") as! TableViewCell

        //text
        cell.previewCommentLabel.text = imageText[indexPath.row]

        //image
        imageFiles[indexPath.row].getDataInBackgroundWithBlock({ ( imageData : NSData?, error : NSError?) -> Void in

            if imageData != nil {
                //ㅇㅋ
                var image = UIImage(data: imageData!)
                cell.previewImage.image = image
            }else {
                println(error)
                //no
            }
        })

        return cell
    }
}

You have a comma in your class definition that isn't needed (after UITableViewDelegate).

Change:

class Home: UIViewController, UITableViewDelegate,  {  //error here "expected identifier for type name"

to:

class Home: UIViewController, UITableViewDelegate  {  //error here "expected identifier for type name"

Using a UITableViewController instead of a UIViewController with UITableViewDelegate shouldn't make much difference, as you will still have to implement the same delegate methods.

However, you will have to implement UITableViewDataSource in order to populate the table view. UITableViewDelegate is for handling selection of rows (etc.) rather than displaying them.

Significantly, tableView:numberOfRowsInSection: and tableView(tableView:cellForRowAtIndexPath: are part of UITableViewDataSource.

You have an extra comma there.

class Home: UIViewController, UITableViewDelegate,  {  //error here "expected identifier for type name"

Should be:

class Home: UIViewController, UITableViewDelegate  {  //error here "expected identifier for type name"
