Only the 1st sentence is displayed after I press the button

Question

When I press the BUTTON for the 1st time, the label displays "Who's is Arnold?"

When I press the BUTTON for the 2nd time I'd want "Who's is Kevin?" to be displayed on the label field, instead of "Who's is Arnold?"

When I press the button for the 3rd time I'd want "Who's is Liu?" to be displayed on the label field, instead of "Who's is Kevin?"

 @IBAction func answerButtonTapped(send: UIButton){ 

   var question = questionField.text 
   var i = 0 


   var listOfQuestions = ["Who is Arnold?", "Who is Kevin?", "Who is Liu?"] 


    for (i=0; i<=listOfQuestions.count; i++){
        questionField.text = "(listOfQuestions[i])"
    } 
}

Answer 1

var counter = 0
var listOfQuestions = ["Who is Arnold?", "Who is Kevin?", "Who is Liu?"]

@IBAction func answerButtonTapped(send: UIButton){ 
  questionField.text = listOfQuestions[counter%listOfQuestions.count] 
  counter++
}
