I can currently get rid of repeating objects in an array, but I want to call that array in the `indexPath.row` method, but I get the error that the variable is not defined since it is declared in a function. I tried instantiating as a nil globally, but that does not get rid of the repeating objects.

```
Var myVar = [<the T type>]()
uniq(<some source>, uniqueTitle: &myVar)

func uniq<S : SequenceType, T : Hashable where S.Generator.Element == T>(source: S) -> [T] {
            var buffer = [T]()
            var added = Set<T>()
            for elem in source {
                if !added.contains(elem) {
                    buffer.append(elem)
                    added.insert(elem)

                }
            }
            return buffer
        }
        //titleatcell is an array with repeating objects.
        titleatcell.append(title!)
        var uniqueTitle = uniq(titleatcell)
        uniqueTitle.append(title!)
        print(uniqueTitle)

     //return count of objects in array
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell = table.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) 

    //Error: uniqueTitle is not declared. 
    cell.textLabel?.text = uniqueTitle[indexPath.row]
    return cell
}

```
