You can create a subclass of UIButton, add one property named parameter which you want to pass as an extra parameter.

In addTarget(), you can only choose passing the caller or not. In this case, the caller is a UIButton.

So use the subclass and call addTarget(), then you can get the string which you want send:

func myFunc(sender: customUIButton) {
    // do something with sender.parameter
}

Hope it can help you.
