I'm trying to capture the long touch on my image. So I can send an action to you in a long touch.

@IBOutlet weak var imageRecord: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()

    let longPressRecognizer = UILongPressGestureRecognizer(target: self, action: #selector(addReconigzer(press:)))
    longPressRecognizer.minimumPressDuration = 1.0
    imageRecord.addGestureRecognizer(longPressRecognizer)
}

@objc func addReconigzer(press:UILongPressGestureRecognizer){
    if press.state == .began
    {
        print("oi amigo")
    }
}

But for some reason the "hi friend" is not printed on my console when I'm preloading the image for a certain time. Can someone tell me where I am wrong or what I should do to be able to have the action performed when I press my image for a long time?

I accept suggestions to be able to do otherwise, already tried to do with button but also not to get someone can help me?

It is necessary to enable user interaction since the image is not an element of interaction initially. This can be done in both the storyboard / XIB and in the code.

No Storyboard:

Or

via code

imageRecord.userInteractionEnabled = true

Tip: Make sure you do not have any other elements on top of the image that is blocking the longpress. (What could be the cause of the button not working)
