You can create an NSMutableArray instance variable to hold the selected values:
var selected = NSMutableArray()
Then, in your didSelectRowAtIndexPath method, add to the array if the object does not exist or remove the object if it does exist.
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let rowValue = dwarves[indexPath.row]; println("You selected cell \(indexPath.row)")
// if the item exsits then remove it
if selected.containsObject(rowValue) {
selected.removeObject(rowValue)
} else { // else the item doesn't exist so add it
selected.addObject(rowValue)
}
println(selected)
}
