How to call a function from a Button in Swift

I am VERY new to Swift! Pleas have mercy on my basic question.

I'm trying programmatically set up a button. I call a function like so:

override func viewDidLoad() { super.viewDidLoad() var yCord1 = 100 var yCord2 = 200 setUpButton("YES", yCord1) setUpButton("NO", yCord2) }

The function:

func setupButton(_ text:String, _ yCord:Int) { let myButton = UIButton() myButton.setTitle(text, for: .normal) myButton.setTitleColor(.white, for: .normal) myButton.backgroundColor = .blue myButton.frame = CGRect(x: 100, y: yCord, width: 100, height: 50) // this didn't work: // myButton.addAction(selector(tapButton()), for: .touchUpInside) // this also didn't work..\ myButton.addTarget(self, action: #selector(buttonTap), for: .touchUpInside) // ADD TO VIEW self.view.addSubview(myButton) }

The function I want the button to call:

func tapButton(_ text:String) { if text == "YES" { print("Yes button has been tapped!") } else { print("NO button tapped") }

I cannot figure out the code to pass in to address assigning a function to the button. It looks like there are 2 options:

myButton.addAction(...

or

myButton.addTarget(...

I couldn't get either to work, I get stuck at what code do I add to the action portion - the for: touchUpInside appears to work OK. I also haven't found an example where I can pass a value through. If that's not possible I think I can develop a work around. Thanks in advance.
