You can implement refresh control like this.

class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {

    @IBOutlet var tableView: UITableView!
    var refreshControl : UIRefreshControl!

}

override func viewDidLoad() {
    super.viewDidLoad()


    self.refreshControl = UIRefreshControl()
    self.refreshControl.backgroundColor = UIColor.clearColor()
    self.refreshControl.tintColor = UIColor.blackColor()

    self.refreshControl.addTarget(self, action: "methodPullToRefresh:", forControlEvents: UIControlEvents.ValueChanged) 

    self.tableView.addSubview(self.refreshControl)

}

func methodPullToRefresh(sender:AnyObject)
{
    self.refreshControl?.beginRefreshing()

}

// Once you are done with your task
self.refreshControl?.endRefreshing()

// Main queue thread is only required when refresh controls comes or goes off with delay, if it works quickly then no need to add this
dispatch_async(dispatch_get_main_queue()) {

}

Hope, this will resolve your problem.

All the best.
