Storyboarded.swift

import UIKit

protocol Storyboarded {
    static func instantiate(storyboardName: String?) -> Self
}

extension Storyboarded where Self: UIViewController {
    static func instantiate(storyboardName: String?) -> Self {
        // this pulls out "MyApp.MyViewController"
        let fullName = NSStringFromClass(self)
        let className = fullName.components(separatedBy: ".")[1]

        // load our storyboard
        let storyboard = UIStoryboard(name: storyboardName ?? "Main", bundle: Bundle.main)

        // instantiate a view controller with that identifier, and force cast as the type that was requested
        return storyboard.instantiateViewController(withIdentifier: className) as! Self
    }
