display a Storyboard from a plugin IOS

Hello, I'm working on an application, who communicate with a plugin iOS that I have code. Howether, it seems that I can't display storyboard who are in these plugins.
This is my code to load my storyboard :
let storyboard = UIStoryboard(name: "Main", bundle: nil)

let vc = storyboard.instantiateViewController(withIdentifier: "StoryboardPhoto")

self.present(vc, animated: true)
I have verify and the name of my storyboard, and his identifier are good. Do I need to add something more in Unity to let it works ?
Thanks for your reply
