"Expected declaration" error, empty last line of file

I am getting a "expected declaration" error on the last (empty) line of my InteractiveStory.swift file.

Here's the github link, I couldn't figure out how to post the code from the file with the error appearing as well.

Firstly, your struct Adventure misses a closing }, which confuses the compiler.

Secondly, you will have to move the return statement in your addChoice method outside the switch statement as below.

func addChoice(title: String, page: Page) -> Page {
        switch (firstChoice, secondChoice) {
        case (.Some, .Some):
            break
        case (.None, .None), (.None, .Some):
            firstChoice = (title, page)
        case (.Some, .None):
            secondChoice = (title, page)
        }

        return page
}

Please note that I have not checked whether that makes sense, it should remove the compiler warnings, though.

Hope that helps :)
