TableView cell select event not triggering

I have created a component in XIB file. This file includes 2 components

  1. Label
  2. TableView

I have then linked and set it's File's Owner class to SampleView. I have attached the XIB file view with SampleView.swift file and this file have only following code in it's class:

@IBOutlet var view: UIView!

I have now created a controller file SampleController with protocols UIViewController, UITableViewDelegate and UITableViewDataSource. I have placed the following code in it's init() func to display the custom component:

init() {
        super.init(nibName: nil, bundle: nil)

        modalPresentationStyle = UIModalPresentationStyle.Custom
        view.addSubview(SampleView())
}

I am using this SampleController to programmatically display as a Modal.

These codes does display as the Modal showing Label and TableView. It also populates the data in TableView. The problem is:

When I tap the cell in table, it doesn't trigger the event on first attempt. When I tap another cell then it trigger the previous cell event.

Any idea why is this happening?

Here are 2 functions used for populating and handling cell tap:

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

        var cell = tableView.dequeueReusableCellWithIdentifier("CELL")
        if (cell == nil) {
            cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "CELL")
        }
        cell!.textLabel?.text = sampleData[indexPath.row]["title"]
        return cell
}

func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
       print("tapped")
}

Darn it! I was using didDeselectRowAtIndexPath instead of didSelectRowAtIndexPath. That's what will happen when you are programming after midnight.

You need to use a different method to dequeue the cell:

var cell = tableView.dequeueReusableCellWithIdentifier("CELL", forIndexPath: indexPath)

The check for a nil cell is unnecessary, by the way.
