Button tap and long press gesture

Hard to say what´s not working with your code, with the only two rows that you have provided, but I would recommend you to do it in this way instead:

Create an outlet to your button instead

@IBOutlet weak var myBtn: UIButton!

And in your viewDidLoad() add the gestures to the buttons

let tapGesture = UITapGestureRecognizer(target: self, action: "normalTap")  
let longGesture = UILongPressGestureRecognizer(target: self, action: "longTap:")
tapGesture.numberOfTapsRequired = 1
myBtn.addGestureRecognizer(tapGesture)
myBtn.addGestureRecognizer(longGesture)

And then create the actions to handle the taps

func normalTap(){

    print("Normal tap")
}

func longTap(sender : UIGestureRecognizer){
    print("Long tap")
    if sender.state == .Ended {
    print("UIGestureRecognizerStateEnded")
    //Do Whatever You want on End of Gesture
    }
    else if sender.state == .Began {
        print("UIGestureRecognizerStateBegan.")
        //Do Whatever You want on Began of Gesture
    }
}

Swift 3.0 version:

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(ViewController.normalTap))
let longGesture = UILongPressGestureRecognizer(target: self, action: Selector(("longTap:")))
tapGesture.numberOfTapsRequired = 1
myBtn.addGestureRecognizer(tapGesture)
myBtn.addGestureRecognizer(longGesture)

func normalTap(){

    print("Normal tap")
}

func longTap(sender : UIGestureRecognizer){
    print("Long tap")
    if sender.state == .ended {
        print("UIGestureRecognizerStateEnded")
        //Do Whatever You want on End of Gesture
    }
    else if sender.state == .began {
        print("UIGestureRecognizerStateBegan.")
        //Do Whatever You want on Began of Gesture
    }
}

Updated syntax for Swift 4.x:

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(normalTap(_:)))
tapGesture.numberOfTapsRequired = 1
myBtn.addGestureRecognizer(tapGesture)

let longGesture = UILongPressGestureRecognizer(target: self, action: #selector(longTap(_:)))
myBtn.addGestureRecognizer(longGesture)

@objc func normalTap(_ sender: UIGestureRecognizer){
    print("Normal tap")
}

@objc func longTap(_ sender: UIGestureRecognizer){
    print("Long tap")
    if sender.state == .ended {
        print("UIGestureRecognizerStateEnded")
        //Do Whatever You want on End of Gesture
    }
    else if sender.state == .began {
        print("UIGestureRecognizerStateBegan.")
        //Do Whatever You want on Began of Gesture
    }
}
