I always seem to forget how to add a target to a button, so that it will automatically run an action or update something immediately. Sometime you just don’t have the brain storage to keep it all in there. So here’s the recipe:

1. Make sure your button(s) have tags. This make it easier to do different actions for different buttons. Set the tag with code or do it in Storyboard.

fizzButton.tag = 3

2. Create a method with an @objc so that your button knows what it should do once it is pressed.

@objc func buttonTapped(sender: UIButton)
{
    if(sender.tag == 3)
    {
        print("hello, fizz") // Do something here for button with tag = 3
    }
}

3. Add the addTarget(_:action:for) method on the button in the viewDidLoad() method.

override func viewDidLoad()
{
    super.viewDidLoad()
    
    fizzButton.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
}

That’s about it.
