Why not use a helper method that you can call inside loadFirstChoice() and loadSecondChoice() to make the code more DRY?

Couldn't you use a nested function that passes the Choice parameter, like so?

func loadFirstChoice() {
    if let page = page, firstChoice = page.firstChoice {
        loadChoice(firstChoice)
    }
}

func loadSecondChoice() {
    if let page = page, secondChoice = page.secondChoice {
        loadChoice(firstChoice)
    }
}

func loadChoice(choice: Choice) {
    let nextPage = choice.page
    let pageController = PageController(page: nextPage)

    navigationController?.pushViewController(pageController, animated: true)
}
