UITapGesture not recognised on the simulator when tapping a UIImageView

Question

I am trying to display a new image based on a user tapping the image view. I have added a UITapGestureRecognizer on top of the UIImageView which has been defined a "displayPhoto" and connected it as an outlet to the view controller.

@IBOutlet weak var displayPhoto: UIImageView! @IBAction func changeImage(_ sender: UITapGestureRecognizer) { displayPhoto.image = UIImage(named: "myimage") }

The sent action is listed as follows:

sent actions

When I run the app and click on the image, nothing happens. I've even tried to make the first line of the IBAction function a fatal error but nothing happens. What am I missing?

Thanks in advance for any help.

The full view and connection

The UIImageView already has "User Interaction Enabled" checked — Jaisal Patel

Also done. If I hover on the filled circle next to the outlet definition, it highlights the tap gesture recogniser on the scene dock — Jaisal Patel

When I hover over the sent action, it highlights the whole view controller. I have just named it view for the sake of the example.. — Jaisal Patel

Have changed the view to be "New item" and pasted a photo showing the reference outlet — Jaisal Patel

Firstly you try; clean your project

command+option+shift+K

The first case cannot be empty

You should add a picture.

 override func viewDidLoad() { super.viewDidLoad() displayPhoto.image = UIImage(named: "firsCase") }

The UIImageView has a default display photo

It is created as nil you created. You have to set the default picture under it. Please You try
