On click just set their text to each other.

var tempString = secondButton.titleLabel.text
secondButton.setTitle(firstButton.titleLabel.text, forState: UIControlState.Normal)
firstButton.setTitle(tempString, forState: UIControlState.Normal)

@IBOutlet var firstButton: UIButton!
@IBOutlet var secondButton: UIButton!

@IBAction func didTouchUpInsideSwapButton() {

    let firstButtonText = firstButton.titleLabel?.text

    firstButton.setTitle(secondButton.titleLabel?.text, for: .normal)
    secondButton.setTitle(firstButtonText, for: .normal)
}
