How to assign an action for UIImageView object in Swift

You'll need a UITapGestureRecognizer.To set up use this:

override func viewDidLoad(){    super.viewDidLoad()    let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped(tapGestureRecognizer:)))    imageView.isUserInteractionEnabled = true    imageView.addGestureRecognizer(tapGestureRecognizer)}@objc func imageTapped(tapGestureRecognizer: UITapGestureRecognizer){    let tappedImage = tapGestureRecognizer.view as! UIImageView    // Your action}

(You could also use a UIButton and assign an image to it, without text and than simply connect an IBAction)

You need to add a a gesture recognizer (For tap use UITapGestureRecognizer, for tap and hold use UILongPressGestureRecognizer) to your UIImageView.

let tap = UITapGestureRecognizer(target: self, action: #selector(YourClass.tappedMe))imageView.addGestureRecognizer(tap)imageView.isUserInteractionEnabled = true

And Implement the selector method like:

@objc func tappedMe(){    println("Tapped on Image")}

You can add a UITapGestureRecognizer to the imageView, just drag one into your Storyboard/xib, Ctrl-drag from the imageView to the gestureRecognizer, and Ctrl-drag from the gestureRecognizer to the Swift-file to make an IBAction.

You'll also need to enable user interactions on the UIImageView, as shown in this image:
