Pick random directory from plist in Swift

I have class like this below to pick questions from plist, but now I want to take them in random order

class QuizLoader {

public func loadSimpleQuiz(forQuiz guizName: String) throws -> [SimpleQuestion] {
    var questions = [SimpleQuestion]()
    if let path = Bundle.main.path(forResource: guizName, ofType: "plist") {
        if let dict = NSDictionary(contentsOfFile: path) {
            let tempArray: Array = dict["Questions"]! as! [Dictionary<String,AnyObject>]
            for dictionary in tempArray {
                let questionToAdd = SimpleQuestion(question: dictionary["Question"] as! String, correctAnswer: dictionary["CorrectAnswer"] as! String)


            }

            return questions

        } else {
            throw LoaderError.dictionaryField
        }

    } else {
        throw LoaderError.pathField
    }
}

I was trying to do this with this hint but I have error with var unsignedArrayCount = UInt32(quoteDictionary.count)

I have already spend few hours trying to figure it out, but still no luck.
