        if let destinationVC = segue.destination as? SignupViewController, let sendData = sender as? {    
            destinationVC.dept = sendData

The problem is that you use Array<NSArray>

  endData = mydata as! Array<NSArray>

and in prepare cast it like

   let sendData = sender as? [String]

which for sure cast will fail
