Can't load data to tableview after it has been passed with delegation

I pass an array with delegation to tableviewcell, where I have tableview. Then I assign this array to an existing array so it should load to tableview. But it seems to be empty. Please, help! 

func passArray(steps: [Step]) {

    self.array = steps
    print(steps)

}


func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return array.count
}

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

    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CellTableViewCell

    cell.textView.text = (array[indexPath.row] as! Step).text as String
    print(11, array)


    return cell
}

and here is where I have declared protocol 

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

    selectedRowIndex = indexPath


    let cell = tableView.cellForRowAtIndexPath(indexPath) as! IdeaTableViewCell

    editButton.frame = CGRect(x: cell.cellView.frame.size.width - 10, y: 15, width: 20, height: 20)
    editButton.setImage(UIImage(named: "change.png"), forState: .Normal)
    editButton.addTarget(self, action: "editButtonSegue", forControlEvents: .TouchUpInside)
    cell.addSubview(editButton)

    cell.cellViewText.text = "\(ideas[indexPath.row].valueForKey("text") as! String). And it is cool because \(ideas[indexPath.row].valueForKey("why") as! String) and it has \((ideas[indexPath.row].valueForKey("steps") as! [Step]).count) steps"

    cell.cellViewTextBottomConstraint.constant = cell.tableView.contentSize.height + 16

    cell.cellViewText.updateConstraintsIfNeeded()
    cell.tableView.updateConstraintsIfNeeded()
    cell.tableView.hidden = false
    cell.tableView.beginUpdates()
    cell.tableView.endUpdates()
    delegate1?.passArray(ideas[indexPath.row].valueForKey("steps") as! [Step])
    tableView.beginUpdates()
    tableView.endUpdates()



}

First of all check your array must not be empty and where you fill your array with values after that call the method 

[self.yourTableViewName reloadData];
