How to detect tableView cell touched or clicked in swift

If you want the value from cell then you don't have to recreate cell in the didSelectRowAtIndexPath

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    println(tasks[indexPath.row])
}

Task would be as follows :

let tasks=["Short walk",
    "Audiometry",
    "Finger tapping",
    "Reaction time",
    "Spatial span memory"
]

also you have to check the cellForRowAtIndexPath you have to set identifier.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("CellIdentifier", forIndexPath: indexPath) as UITableViewCell
    var (testName) = tasks[indexPath.row]
    cell.textLabel?.text=testName
    return cell
}

Hope it helps.

In Swift 3.0

You can find the event for the touch/click of the cell of tableview through it delegate method. As well, can find the section and row value of the cell like this.

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
       print("section: \(indexPath.section)")
       print("row: \(indexPath.row)")
}
