@objc

I don't know if this is due to Swift being updated to Swift 4 as I went through this course, but I was forced, by XCode, to add @objc to the front of my loadFirstChoice() and loadSecondChoice() methods.

Example:

 @objc func loadFirstChoice() {
         if let page = page, let firstChoice = page.firstChoice {
             let nextPage = firstChoice.page
             let pageController = PageController(page: nextPage)
             navigationController?.pushViewController(pageController, animated: true)
        }
    }

Some clarification on what this means and why we need it would be helpful.
