Sample TableView not print the array Swift OSX - macos

Question

I have the next code in my application but only print the next image,i don't know why.Someone who can help me solve this error.I think that the error is in the Dictionary.
import Cocoa
class ViewController: NSViewController {
#IBOutlet weak var viewTable: NSTableView!
func getDataArray () -> NSArray{
var dataArray:[NSDictionary] = [["FirstName": "Debasis", "LastName": "Das"],
["FirstName": "Nishant", "LastName": "Singh"],
["FirstName": "John", "LastName": "Doe"],
["FirstName": "Jane", "LastName": "Doe"],
["FirstName": "Mary", "LastName": "Jane"]];
return dataArray;
}
func numberOfRowsInTableView(aTableView: NSTableView!) -> Int
{
let numberOfRows:Int = getDataArray().count
return numberOfRows
}
func tableView(tableView: NSTableView!, objectValueForTableColumn tableColumn: NSTableColumn!, row: Int) -> AnyObject!
{
var newString: (AnyObject?) = getDataArray().objectAtIndex(row).objectForKey(tableColumn.identifier)
println(newString)
return newString;
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override var representedObject: AnyObject? {
didSet {
}
}
}
Maybe it's silly but it's good to know how to do, I hope it will be useful.Finally my code works, the only thing he needed was set as data source.

Have you set the Identifier for the cells in the storyboard? If so then just get the row and with the identifier you can get the "FirstName" or "LastName", wich you return
func tableView(tableView: NSTableView, objectValueForTableColumn tableColumn: NSTableColumn?, row: Int) -> AnyObject?
{
var columnIdentifier = tableColumn!.identifier
var newString: (AnyObject?)
newString = getDataArray().objectAtIndex(row).valueForKey(columnIdentifier)
println(newString)
return newString
}
If you have further questions how to work with cell based tableViews: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/TableView/PopulatingCellTables/PopulatingCellTables.html
Edit:
you should set the tableView as Cell Based.
And i think you forget to set ViewController as dataSource and delegete for the tableview in the Storyboard
