@objc func longPress(gesture: UILongPressGestureRecognizer) {
    if gesture.state == UIGestureRecognizerState.began {
        print("Long Press")

func addLongPressGesture(){
    let longPress = UILongPressGestureRecognizer(target: self, action: #selector(longPress(gesture:)))
    longPress.minimumPressDuration = 1.5
    self.countButton.addGestureRecognizer(longPress)
}

Why not create a custom UIButton class, create a protocol and let the button send back the info to delegte. Something like this:

    //create your button using a factory (it'll be easier of course)
    //For example you could have a variable in the custom class to have a unique identifier, or just use the tag property)

    func createButtonWithInfo(buttonInfo: [String: Any]) -> CustomUIButton {
        let button = UIButton(type: .custom)
        button.tapDelegate = self
        /*
Add gesture recognizers to the button as well as any other info in the buttonInfo

*/
        return button
    }

    func buttonDelegateReceivedTapGestureRecognizerFrom(button: CustomUIButton){
        //Whatever you want to do
    }

If you want to perform any action with single tap you and long press the you can add gestures into button this way:

@IBOutlet weak var btn: UIButton!

override func viewDidLoad() {

    let tapGesture = UITapGestureRecognizer(target: self, #selector (tap))  //Tap function will call when user tap on button
    let longGesture = UILongPressGestureRecognizer(target: self, #selector(long))  //Long function will call when user long press on button.
    tapGesture.numberOfTapsRequired = 1
    btn.addGestureRecognizer(tapGesture)
    btn.addGestureRecognizer(longGesture)
}

@objc func tap() {

    print("Tap happend")
}

@objc func long() {

    print("Long press")
}

This way you can add multiple method for single button and you just need Outlet for that button for that..
