uitableview - Swift: Pass UITableViewCell label to new ViewController

Question

I have a UITableView that populates Cells with data based on a JSON call. like so:

var items = ["Loading..."]
var indexValue = 0

// Here is SwiftyJSON code //

for (index, item) in enumerate(json) {
    var indvItem = json[index]["Brand"]["Name"].stringValue
    self.items.insert(indvItem, atIndex: indexValue)
    indexValue++
}
self.tableView.reloadData()

How do I get the label of the cell when it is selected and then also pass that to another ViewController?

I have managed to get:

func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
    println("You selected cell #(indexPath.row)!")

    // Get Cell Label
    let indexPath = tableView.indexPathForSelectedRow();
    let currentCell = tableView.cellForRowAtIndexPath(indexPath!) as UITableViewCell!;

    println(currentCell.textLabel.text)
}

I just cant figure out how to pass that as a variable to the next UIViewController.

Thanks

Passing data between two view controllers depends on how view controllers are linked to each other. If they are linked with segue you will need to use performSegueWithIdentifier method and override prepareForSegue method

var valueToPass:String!

func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
    println("You selected cell #(indexPath.row)!")

    // Get Cell Label
    let indexPath = tableView.indexPathForSelectedRow();
    let currentCell = tableView.cellForRowAtIndexPath(indexPath!) as UITableViewCell!;

    valueToPass = currentCell.textLabel.text
    performSegueWithIdentifier("yourSegueIdentifer", sender: self)

}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    if (segue.identifier == "yourSegueIdentifer") {

        // initialize new view controller and cast it as your view controller
        var viewController = segue.destinationViewController as AnotherViewController
        // your new view controller should have property that will store passed value
        viewController.passedValue = valueToPass
    }

}

If your view controller are not linked with segue then you can pass values directly from your tableView function

func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
    println("You selected cell #(indexPath.row)!")

    // Get Cell Label
    let indexPath = tableView.indexPathForSelectedRow();
    let currentCell = tableView.cellForRowAtIndexPath(indexPath!) as UITableViewCell!;
    let storyboard = UIStoryboard(name: "YourStoryBoardFileName", bundle: nil)
    var viewController = storyboard.instantiateViewControllerWithIdentifier("viewControllerIdentifer") as AnotherViewController
    viewController.passedValue = currentCell.textLabel.text
    self.presentViewController(viewContoller, animated: true , completion: nil) 
}
