Passing data between view controllers using segues

segue.rb

class MyViewController < UITableViewController
  
  attr_accessor :datasource
  
  # .. UITableViewController delegate methods here ..
  
  def prepareForSegue(segue, sender: sender)
    if (segue.identifier.isEqualToString("segueIdentifier"))
      index_path = @datasource.indexPathForSelectedRow
      destination_view_controller = segue.destinationViewController
      
      # Given that the destination view controller has attr_accessor :datasource
      destination_view_controller.datasource = @datasource[index_path.row]
    end
  end
  
end
