You'll need a <code>UITapGestureRecognizer</code>.
To set up use this:

<pre><code>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
}
</code></pre>

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

You need to add a a gesture recognizer (For tap use <a href="https://developer.apple.com/library/ios/documentation/UIKit/Reference/UITapGestureRecognizer_Class/index.html" rel="noreferrer">UITapGestureRecognizer</a>, for tap and hold use <a href="https://developer.apple.com/library/ios/documentation/UIKit/Reference/UILongPressGestureRecognizer_Class/index.html" rel="noreferrer">UILongPressGestureRecognizer</a>) to your <code>UIImageView</code>.

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

And Implement the selector method like:

<pre><code>@objc func tappedMe()
{
 println("Tapped on Image")
}
</code></pre>

You can add a <code>UITapGestureRecognizer</code> 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 <code>IBAction</code>.

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

You could actually just set the image of the <code>UIButton</code> to what you would normally put in a <code>UIImageView</code>. For example, where you would do:

<pre><code>myImageView.image = myUIImage
</code></pre>

You could instead use:

<pre><code>myButton.setImage(myUIImage, forState: UIControlState.Normal)
</code></pre>

So, here's what your code could look like:

<pre><code>override func viewDidLoad(){
 super.viewDidLoad()

 var myUIImage: UIImage //set the UIImage here
 myButton.setImage(myUIImage, forState: UIControlState.Normal)
}

@IBOutlet var myButton: UIButton!
@IBAction func buttonTap(sender: UIButton!){
 //handle the image tap
}
</code></pre>

The great thing about using this method is that if you have to load the image from a database, you could set the title of the button before you set the image:

<pre><code>myButton.setTitle("Loading Image...", forState: UIControlState.Normal)
</code></pre>

To tell your users that you are loading the image

I'm trying to assign an <code>UIImageView</code> to an action when the user taps it.

I know how to create an action for a <code>UIButton</code>, but how could I mimic the same behavior of a <code>UIButton</code>, but using a <code>UIImageView</code>?
