初始化程序只能在类型内声明

Question

import UIKit

func Question() {
    var questiontext : String
    var answer : Bool

    init(text: String , correctanswer: Bool ){ //error in this point : Initializers may only be declared within a type
        questiontext = text
        answer = correctanswer
    }
}

我该如何解决这个问题？

Answer 1

init应该在class / struct类型内，而不是func

class Question { 
    var questiontext : String
    var answer : Bool 
    init(text: String , correctanswer: Bool ){  
        questiontext = text
        answer = correctanswer
    } 
}
