I am able to bind Data from bottom of TableView. All credit goes to Rajeshkumar R for helping me.

Step 1, apply a transform to the table view rotating it 180deg

tableView.transform = CGAffineTransformMakeRotation(-M_PI);

Step 2, rotate your raw cell 180deg in tableView:cellForRowAtIndexPath:

cell.transform = CGAffineTransformMakeRotation(M_PI);

Step 3, reverse your datasource. If you're using an NSMutableArray insert new objects at location 0 instead of using AddObject... Now, the hard part is remembering that left is right and right is left only at the table level, so if you use

[tableView insertRowsAtIndexPaths:targetPath withRowAnimation:UITableViewRowAnimationLeft]

you can use the function below. It worked for me.

func scrollToLastRow() {
    let indexPath = NSIndexPath(row: messageHistoryArray.count-1, section: 0)
    self.createChatTableView.scrollToRow(at: indexPath as IndexPath, at: .bottom, animated: true)
}
