SWIFT:如果问题有不同的分数，请跟踪分数

Question

如果我想跟踪我的分数，我正在尝试创建一个测验应用程序。

但是，问题的分数都有一些不同的价值。我希望分数加上前面的值。

到目前为止，这是我的代码。我期待着你的回答。非常感谢。

(我对结构和问题有单独的看法(

当你看到我的代码时，如果你看到一些可以改进的地方，请让我知道

在变异函数ScoreUP中，对得分变量进行以下更新

if userChoice == currentStory.choice1 {
score += Int(Double(currentStory.scoreX1))
} else if userChoice == currentStory.choice2 {
score += Int(Double(currentStory.scoreX2))
}
