Swift - Quiz App Review

// **Update Here**
 
// This is how I have tried to go about giving the user their results.
 
// So basically what I tried to do was enumerate the question array and pull out all the users answers and the correct answers and // // append them to a new array.
 
// users answers go to userAnswers
 
// correct answers go to correctAnswers
 
// Then it calls a function checkResults that will check how many answers the user got wrong or right.
 
// This is where I got stuck. I used a map function to compare the 2 arrays and give me a new array back called answer. If the answers // matched the it would return true and if they didn`t it would return false.
 
// Now I am not entirely sure how to convert the results inside answer into Correct or Incorrect.
 
// I tried using something like this:
 
// var finalResults = answer.map({"The following answer is \($0)"})
// But I still do not know the best way to convert the answer array to Strings.
 
// Eventually I plan to display the results of that array into a table view (which I know how to do) so it says something like "This // answer was correct" or "This answer was incorrect".




@IBAction func submitAll(sender: UIButton) {

    let hasAnsweredAllQuestions = questions.reduce(true) { (x, q) in x && (q.usersAnswer != nil) }
    println("has user answered all questions?: \(hasAnsweredAllQuestions)")

    for (index, _) in enumerate(questions) {
        userAnswers.append(questions[index].usersAnswer!)
        correctAnswers.append(questions[index].answer)
    }
    if correctAnswers.count == 3 {
        checkResults()
    }
}
