I know how to add tags in main.storyboard
files, but now I am working on creating everything programmatically. However, I couldn't find anything online that tells me how to add tags to a button. I tried to read the apple documentation but don't know how to implement it.
Here is for example how I created my button, how can I add a tag to it, so that when I make multiple buttons and want to link them to a single action I can know what button has been pressed?
let buttonOne() : UIButton {
let button = UIButton(type: .system)
button.backgroundColor = .red
return button
}()

Declare The Button
let menuChooseButton = UIButton()
menuChooseButton.frame.origin.y = 0
menuChooseButton.frame.origin.x = xPosition
menuChooseButton.frame.size.width = subViewWidth
menuChooseButton.frame.size.height = subViewHeight
menuChooseButton.backgroundColor = .clear
menuChooseButton.setTitle("", for: .normal)
menuChooseButton.tag = i
menuChooseButton.addTarget(self, action: #selector(menuSelectAction), for: .touchUpInside)
menuScrollView.addSubview(menuChooseButton)
Define Button Action
@objc func menuSelectAction(sender: UIButton!){
var tagNo: Int = sender.tag
if tagNo == 0{
// Whatever you want
}
}

Try this:
let buttonOne() : UIButton {
let button = UIButton(type: .system)
button.backgroundColor = .red
button.tag = 2
return button
}()
