Add delegate and dataSource for extension view - ios

Question

First of all, I'm not sure the name of it is "extension view", please look at the screenshot, I mean the view with the yellow background.
I have made a custom table view in this view, and I did all the configurations, the problem is, in the end, I have to add delegate and dataSource for it.
Let's call the table cell inside of the view "OptionTableView".
I wrote these lines the viewdidload of the view controller (the controller that is inside the iPhone frame in the screenshot),
override func viewDidLoad() {
super.viewDidLoad()
OptionTableView.delegate = self
OptionTableView.dataSource = self
}
but it crashes the app with this error:
Thread 1: signal SIGABRT
Because it's UiView, I can't make a new file with a type of UIControlView for it.
Could you help me? How I can add delegate and dataSource for this extension UIView or whatever is called, that let me to use tableview inside it?
Thank you so much for your help

I think you not add protocol of tableview. I write a code for this:-
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var table_view: UITableView!
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell()
return cell
}
override func viewDidLoad() {
super.viewDidLoad()
table_view.dataSource = self
table_view.delegate = self
}
}
