Why do I get an EXC_BAD_ACCESS Error when deleting values from a UITableView?

I am creating an app where I have data stored in a UITableView inside a view controlled by a class I have created, TeamsViewController. I have code to delete values from the table, but sometimes (not always), the app will crash when you delete values from the table view.

I get the error Thread 1: EXC_BAD_ACCESS (code=1, address=0x0) on the class declaration of my AppDelegate:

class AppDelegate: UIResponder, UIApplicationDelegate

Here is the code for TeamsViewController:

@IBOutlet weak var table: UITableView!
var data: [Team]()

override func viewDidLoad()
{
    super.viewDidLoad()

    if(table != nil)
    {
        self.table.delegate = self
        self.table.dataSource = self
        self.table.reloadData()
    }
}
func tableView(tableView: UITableView!, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath!)
{
    println("1234")
    if (editingStyle == UITableViewCellEditingStyle.Delete)
    {
        data.removeAtIndex(indexPath.row)
        table.reloadData()
    }
}

Note that Team is a class that I have created .

I have omitted some of the tableView code, tell me if it is needed and I will add it.

Some more information that might be helpful is that "1234" is NOT printed to the console when the app crashes.

Thank you in advance.

I'm not certain what error it is, but based on a tutorial I did on tableViews, their swipe-to-delete function override contained this line:

tableView.deleteRowsAtIndexPaths(indexPaths, withRowAnimation: .Automatic)

Maybe adding that line would clear your error.
