How to pass prepareForSegue: an object

Question

I have many annotations in a mapview (with rightCalloutAccessory buttons). The button will perform a segue from this mapview to a tableview

Answer 1

Just use this function.

 override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    let index = CategorytableView.indexPathForSelectedRow
    let indexNumber = index?.row
    let VC = segue.destination as! DestinationViewController
   VC.value = self.data

}
