Dynamically Setting Row height in Tableview works on some cells only - uitableview

Question

I have a table view where rows are populated with data from an array.
Row height is set dynamically in viewDidLoad() by calling this function:
func configureTableView() {
/* When you set the rowHeight as UITableViewAutomaticDimension, the table view knows to use the auto layout constraints to determine each cell’s height. This also reuqires a estimetedRowHeoght, an arbitary number */
println("Configure Table View called")
tableView.estimatedRowHeight = 74.0;
tableView.rowHeight = UITableViewAutomaticDimension;
tableView.separatorStyle = UITableViewCellSeparatorStyle.None;
}
The data to populate each row is loading into arrays aysnrounscly from Parse.
Once data is loaded into arrays I then call:
self.tableView.reloadData();
self.configureTableView();
... in order to reload table row data and then re-conguire the row height dynamically, according to size of comments populating label within a row.
Problem is two fold:
Only some rows have the height set dynamically, other rows the row height appears to be fixed you can't view the comments if more than one line
When user scrolls the tableview, the refreshed view all rows are static, none appear to have height set dynamically, only one line of comment can be seen.
Any input appreciated
I am also using a footer view which is created programmictally with code to allow fro showing and hiding the keyboard, i think this may of something to do with it ....
// viewDidlOad
/* Setup the keyboard notifications so does not block textview for adding comments */
NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyBoardWillShow:", name: UIKeyboardWillShowNotification, object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyBoardWillHide:", name: UIKeyboardWillHideNotification, object: nil)
/* Setup the contentInsets fo keyboard */
self.tableView.contentInset = UIEdgeInsetsZero
self.tableView.scrollIndicatorInsets = UIEdgeInsetsZero
self.edgesForExtendedLayout = UIRectEdge.None
/* Make sure the content doesn't go below tabbar/navbar */
self.extendedLayoutIncludesOpaqueBars = true
self.automaticallyAdjustsScrollViewInsets = false
Apologies in advance but Allot of code here for setting up footer view and handling user input....
