Adding a table row object to a PFRelation

I'm creating a table with a list of users, when the users are pressed they are then added to a PFRelation in the user's class. When I write objectAtIndex it underlines it and throws an error. The Code is..

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        var cell:UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
        cell.accessoryType = UITableViewCellAccessoryType.Checkmark

        var relation : PFRelation = PFUser.currentUser().relationForKey("friendship")
        let user:PFObject = self.userArray.objectAtIndex(indexPath.row) as PFObject

        PFUser.currentUser().saveInBackgroundWithBlock { (succeed:Bool, error: NSError!) -> Void in
            if error != nil {
                NSLog("Unable to save")


The array if defined here..

    var userArray: [String] = []

    override func viewDidLoad() {

        var query = PFUser.query()
        query.whereKey("username", notEqualTo: PFUser.currentUser().username)
        var users = query.findObjects()
        for user in users {



Any help would be greatly appreciated. Thanks, Chris

var allUsers:NSArray = [] // NSArray *allUsers . . . try this

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    self.tableView.deselectRowAtIndexPath(indexPath, animated: false)

    var cell = tableView.cellForRowAtIndexPath(indexPath)
    cell!.accessoryType = UITableViewCellAccessoryType.Checkmark

    var user = self.allUsers[indexPath.row] as! PFUser
    var friendsRelation = self.currentUser!.relationForKey("friendsRelation")
    self.currentUser!.saveInBackgroundWithBlock {
        (success: Bool, error: NSError?) -> Void in
        if (success) {
            // The post has been added to the user's likes relation.
        } else {
            // There was a problem, check error.description
            println("Error: \(error!)\(error!.userInfo)")

and dont forget to add this

class EditFriendsController: UITableViewController, UITableViewDataSource, UITableViewDelegate {


stuck in at least a couple of hours because of this "UITableViewDataSource & UITableViewDelegate"
