Need help displaying a page made with Scenes into an App in iOS made with View Controllers and Storyboards

I have a 1 page app that was created for me, but it was made with the Scenes feature of XCode and my app that I'm trying to copy it into is made with View Controllers and Storyboards. I think I have to make the scene page into a "widget" or something with its own target to get it to work in my existing app.

I'm getting a lot of the "main" errors. I would like help fixing this asap. Thanks!
