Protocol extension not recognized in class definition

In my iOS project I have this file:

import UIKit

protocol ViewController {
    static func instantiate() -> Self
}

extension ViewController {
    static func instantiate() -> Self {
        let fullName = NSStringFromClass(self)
        let className = fullName.componentsSeparated(by: ".")[1]
        let storyboard = UIStoryboard(name: "Main", bundle: Bundle.mainBundle)
        let controller = storyboard.instantiateViewController(withIdentifier: className) as! Self

        return controller
    }
}

The in my controller file I have this:

@IBObject public class RootViewController: UITableViewController, ViewController {
. . .
}

Shouldn’t it recognize the default implementation of the instantiate method? It’s giving an error on the class declaration saying the static func instantiate() not implemented.

It should, yeah. does it wort if you add the method body tight in the protocol declaration?
