How to resolve this error 'Could not cast value of type 'UITableViewController' (0x1049b9668) to 'SliderMenuStatic.SubMenuTableViewController' (0x1028dae80)'

I am trying to pass date from one TableViewController to another TableViewController but I am gettiing this error in prepareForSegue function.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

if (segue.identifier == "passMenu") {

let DirectionviewController = segue.destinationViewController as! SubMenuTableViewController

print("valueToPass", valueToPass)

DirectionviewController.title = valueToPass

}

}
