I screw up on the every time  Just make sure the tableView delegate and dataSource are declared in viewDidLoad  Then I normally populate a few arrays to simulate returned data and then take it from there              Populate Table with data             public func tableView   tableView  UITableView  cellForRowAt indexPath  IndexPath  - gt  UITableViewCell       let cell   tableView dequeueReusableCell withIdentifier   Cell   as  SetupCellView     cell  ControllerLbl text   ViewContHeading indexPath row      cell  DetailLbl text   ViewContDetail indexPath row      cell  StartupImageImg image   UIImage named  ViewContImages indexPath row       return cell

A of couple things that need to happen      The view controller needs to extend the type UITableViewDelegate The view controller needs to include the didSelectRowAt function  The table view must have the view controller assigned as its delegate      Below is one place where assigning the delegate could take place  within the view controller    override func loadView         tableView dataSource   self     tableView delegate   self     view   tableView     And a simple implementation of the didSelectRowAt function   func tableView   tableView  UITableView  didSelectRowAt indexPath  IndexPath        print  row    indexPath row

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  - gt  UITableViewCell       let cell   tableView dequeueReusableCellWithIdentifier  CellIdentifier   forIndexPath  indexPath  as UITableViewCell     var  testName    tasks indexPath row      cell textLabel  text testName     return cell     Hope it helps

Inherit the tableview delegate and datasource  Implement delegates what you need       override func viewDidLoad             super viewDidLoad           tableView delegate   self         tableView dataSource   self         And Finally implement this delegate       func tableView   tableView  UITableView  didSelectRowAt        indexPath  IndexPath         print  row selected     indexPath row
