Populating two types of UITableViewCell in a single UITableView

I have a ViewController called notificationsVC with two tableViews - notifTable and messageTable. In notifTable I have two types of UITableViewCells -

enter image description here

As you can see there's a followed you and commented/liked your post patterns. Until now I have been using two UITableViewCell's like this. (reuse identifier - cell1 and cell3)

enter image description here

The first one I made a coach touch file named notification_cell.swift and another notification2_cell.swift

notification_cell.swift

import UIKit
class notification_cell: UITableViewCell {    
    @IBOutlet weak var profilePic: UIImageView!    
    @IBOutlet weak var username: UILabel!    
    @IBOutlet weak var followNotif: UILabel! 
}

notification2_cell.swift

import UIKit
class notification2_cell: UITableViewCell {    
    @IBOutlet weak var profilePic: UIImageView! 
    @IBOutlet weak var username: UILabel!    
    @IBOutlet weak var c_l_notif: UILabel!    
    @IBOutlet weak var postImage: UIImageView!
}

I have four arrays in all -

var username = [String]()
var notif = [String]()
var u_id = [String]()
var p_id = [String]()

For eg, when I do a API call I get this

username-> ["Anton Griezmann", "Anonymous", "Anonymous"]
u_id-> ["2", "30", "31"]
notif-> ["followed you", "liked your post", "liked your post"]
p_id-> ["", "9", "9"]

What I'm trying to do is whenever there's a blank "" in p_id I know I have to initialise cell1 and otherwise cell3

This is my code for cellForRowAtIndexpath

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) ->
    UITableViewCell{
        var cell = UITableViewCell()
        var index = [Int]()

        if(tableView==self.notifTable)
        {
            for i in 0..<p_id.count {
                if p_id[indexPath.row].isEmpty {
                    index.append(i)

                //cell for followed you
                let cell = tableView.dequeueReusableCellWithIdentifier("cell1", forIndexPath: indexPath) as! notification_cell
                    cell.username.text = username[indexPath.row]
                    cell.followNotif.text =
                    notif[indexPath.row]
                    return cell

                }
                else {

                    //cell for commented/liked
                    let cell = tableView.dequeueReusableCellWithIdentifier("cell3", forIndexPath: indexPath) as! notification2_cell
                    cell.username.text = username[indexPath.row]
                    cell.c_l_notif.text = notif[indexPath.row]
                    return cell

                }

            }

        }
        else
        {
            let cell = tableView.dequeueReusableCellWithIdentifier("cell2", forIndexPath: indexPath)
            cell.textLabel?.text = "hola"

            return cell

        }


}

What I get when I run it is this

enter image description here

That is the first cell is getting overwritten again. I need a way to find out which cell should be initialised at what indexPath but can't think of how. Any suggestions are welcome!

First of all you are returning wrong cell in your cellForRowAtIndexPath try to return cell inside the if - else block, and if you want to check for p_id[indexPath.row] is "" means it is empty so you can check its length or use isEmpty function of String, There is no need to go through a loop, Also.

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

        if(tableView==self.notifTable)
        {
            if (p_id[indexPath.row].isEmpty) {

                //cell for followed you
                let cell = tableView.dequeueReusableCellWithIdentifier("cell1", forIndexPath: indexPath) as! notification_cell
                cell.username.text = username[indexPath.row]
                cell.followNotif.text =
                    notif[indexPath.row]
                return cell
            }
            else {

                //cell for commented/liked
                let cell = tableView.dequeueReusableCellWithIdentifier("cell3", forIndexPath: indexPath) as! notification2_cell
                cell.username.text = username[indexPath.row]
                cell.c_l_notif.text = notif[indexPath.row]
                return cell
            }
        }
        else
        {
            let cell = tableView.dequeueReusableCellWithIdentifier("cell2", forIndexPath: indexPath)
            cell.textLabel?.text = "hola"

            return cell

        }            
}
