Array of 2 button to add at view - xcode

Question

func addStartingButtons2() {
let button = UIButton(frame: CGRect(x: 50, y: buttonY, width: 250, height: 30))
button.layer.cornerRadius = 10 // get some fancy pantsy rounding
button.backgroundColor = UIColor.darkGray
button.setTitle("Button for Villain: \(String(describing: hashes[button]))", for: UIControlState.normal)
buttons.append(button)
buttons.append(button)
for button in buttons {
self.view.addSubview(button)
button.frame.origin.y += 50
}
}
Where:
var hashes = [UIButton : [Double]]()
var buttons = [UIButton]()
Want to add this function 2 same buttons one onder other, but only one button is realised

Answer 1

Well yeah, you are trying to add the same button twice.
I didn't test the code but you should be able to do this by putting the logic in a for loop and adding a bit of padding between the buttons, otherwise you will see them overlapping.
Something like this:
func addStartingButtons2() {
for villain in villains { // this depends on your needs, it's just an example
let button = UIButton(frame: CGRect(x: 50, y: buttonY, width: 250, height: 30))
// Add offset for the next button.
buttonY += 40
button.layer.cornerRadius = 10 // get some fancy pantsy rounding
button.backgroundColor = UIColor.darkGray
button.setTitle("Button for Villain: \(String(describing: hashes[button]))", for: UIControlState.normal)
buttons.append(button)
}
for button in buttons {
self.view.addSubview(button)
button.frame.origin.y += 50
}
// If you want to avoid the second loop
// you can just put view.addSubview(button) inside the first for loop
}

Answer 2

This won't work. Your array buttons is storing a reference of your button, so you are actually putting two references into the array.
To see the result by yourself, put a break point in your loop and you will see the button with same address twice.
If you want to have multiple buttons, you have to create them one by one.
