You can put an UITapGestureRecognizer inside your UIImageView using Interface Builder or in code (as you want), I prefer the first. The you can put an @IBAction and handle the tap inside your UIImageView , Don't forget to set the UserInteractionEnabled to true in Interface Builder or in code.

To present the next view controller you can do it in code like below or just using Interface Builder using a segue through the UITapGestureRecognizer you set before (it's up to you).

To present the view controller manually like in the following code you need to set the Storyboard ID for you view controller like in the following picture (in the Identity Inspector panel ):

@IBAction func imageTapped(sender: AnyObject) {

    // Set the storyboard name by default is Main
    let storyboard = UIStoryboard(name: "MyStoryboardName", bundle: nil)

    // Instantiate the ViewController with the name you set before like in the image
    let nextViewController = storyboard.instantiateViewControllerWithIdentifier("ViewControllerB") as! UIViewController

    // present the nextViewController
    self.presentViewController(nextViewController, animated: true, completion: nil)
}

I hope this help you.
