I'm calling my presenter functon that is listed in a protocol that my presenter is implementing but whenever i call it it never goes inside, 
how do i initilize my presenter so i can call the interface funcion ?

here is my view controller:

```
import UIKit

class FirstScreenViewController: UIViewController, MainViewProtocol {

    var myPresenter: MainPresenterProtocol?

    func outputPresenterFunction() {
       print (myPresenter?.presenterProtocolFuncTwo(numOne: 2, numTwo: 4, sucssesMessage: "Made it ?", failMessage: "failed :(" ) ?? "Default landed")
    }

}

```

in my presenter i have:

```
import Foundation

class MainPresenter: MainPresenterProtocol {

    var screenViewController: MainViewProtocol?

    func presenterProtocolFuncTwo(numOne: Int, numTwo: Int, sucssesMessage: String, failMessage: String) -> String {
        print("function is called")
        return "presenter function is called sussfuly"
    }

}

```

and my protocol itself:

```
protocol MainViewProtocol {
    func showSmallHeadline(textToShow: String)
    func showHeadline(textToShow: String)
}

protocol MainPresenterProtocol {
    static func presenterProtocolFuncOne()
    func presenterProtocolFuncTwo(numOne: Int, numTwo: Int, sucssesMessage: String, failMessage: String) -> String
    func presenterProtocolFucThree () -> Bool
}

```

whenever i call the presenterProtocolFuncTwo, i get my default value and it doens't go inside the function in my presenter
