ios - 未使用结构

Question

我的应用程序包含 50 多个问题。每个问题都有:

1. 一个问题，
2. 正确答案
3. 三个错误答案
4. 图像名称

所以我用这些属性创建了一个结构。屏幕上一次只会显示一个问题，因此我开始设置我的问题，如下所示:

let question1 = structName... (pass question info)
let question2 = structName... (pass question 2 info)

但是，这会收到“变量未使用”警告。我做错了什么以及我该怎么做？

Answer 1

我无法将错误的答案合并到一个数组中，但我可以通过将所有结构存储在一个数组中来使用此设计模式，这确保了它们全部被使用:

    //Question one
    let questionPackage = QuestionInfo(
        questionNum: 1,
        questionType: "Single",
        answer: "Correct answer here",
        wrongAnswer_1: "This is wrong",
        wrongAnswer_2: "So is this",
        wrongAnswer_3: "So is not right"
    )

    //Question two
    let questionPackage2 = QuestionInfo(
        questionNum: 1,
        questionType: "Single",
        answer: "Correct answer here",
        wrongAnswer_1: "This is wrong",
        wrongAnswer_2: "So is this",
        wrongAnswer_3: "So is not right"
    )

    let questionArray = [questionPackage,questionPackage2]
    let loadQuestion = questionArray[questionNum]
