randomize elements in a class swift 4 [duplicate]

• How do I shuffle an array in Swift? 21 answers

Very new to Swift and rusty developing in general

I have a questionnaire style app, where users can respond to questions, I want to keep track of the correct and incorrect responses as they answer.

I have it working for a known number of questions, but want to build an array of random questions from the base 9 possible responses.

TLDR can you build a randomised array of questions from a class?

class Question {
let questionSymbol : String
let answer : Int
init(text: String, correctAnswer: Int){
    questionSymbol = text
    answer = correctAnswer
}

}

class QuestionBank {
var list  = [Question]()

init() {
    let item = Question(text : "\u{2265}",correctAnswer : 1)
    list.append(item)
    list.append(Question(text : "\u{00B1}", correctAnswer : 2 ))
    list.append(Question(text : "\u{226A}", correctAnswer : 3 ))
    list.append(Question(text : "\u{03A0}", correctAnswer : 4 ))
    list.append(Question(text : "\u{0436}", correctAnswer : 5 ))
    list.append(Question(text : "\u{03C8}", correctAnswer : 6 ))
    list.append(Question(text : "\u{2206}", correctAnswer : 7 ))
    list.append(Question(text : "\u{26AC}", correctAnswer : 8 ))
    list.append(Question(text : "\u{2191}", correctAnswer : 9 ))
}
}

I have looked and seen a number of randomisation things arc4random etc, but I am not sure how to build an array of say 150 random questions preserving the above structure in an array type based on this...!
