A small protocol to remove the need for your view controllers to use tricky #selector syntax

SelectorContext.swift

import UIKit

@objc protocol SelectorContext {

    var selector: Selector { get }
    func selectorCallback(_ sender: Any)
}

extension UIViewController: SelectorContext {

    var selector: Selector {
        return #selector(selectorCallback(_:))
    }

    func selectorCallback(_ sender: Any) {}
}
