Below is just an example to get you started.
First define the location of the view controller:
let contentRect = CGRectMake(0, 30, self.view.bounds.size.width, 100)
Then you need to setup your UITableViewController and set the delegate and the datasource and add it as a child view to the main view controller:
resultsController = UITableViewController(style: UITableViewStyle.Plain)
resultsController.tableView.delegate = self
resultsController.tableView.dataSource = self
resultsController.view.frame = contentRect
self.addChildViewController(resultsController)
self.view.addSubview(resultsController.view)
resultsController.didMoveToParentViewController(self)
You put the entire code where you want to show the search results tableview.
