    if answerButton.tag == 1 {

    answerButton.setTitle(questionBank.list[questionNumber].answer1, 
    for: .normal)
    } else if answerButton.tag == 2 {

    answerButton.setTitle(questionBank.list[questionNumber].answer2, 
    for: .normal)
    } else if answerButton.tag == 3 {

  answerButton.setTitle(questionBank.list[questionNumber].answer3,

You can create your @IBOutlet collection, for example:

@IBOutlet private var buttons: [UIButton]!

Then in your function:

@IBAction func answerButtonAction(_ sender: UIButton) {  

    let answers = [que.answer1, que.answer2, ...]

    zip(buttons, answers).forEach { (button, answer) in
        button.setTitle(answer, for: .normal)
    }              
}

//Setting UIButton title

let button = UIButton()

button.setTitle("My Amazing Button", for: .normal)
