title: How to detect which image has been tapped in swift
body: <p>I have created 6 UIImageViews on a ViewController, and I am later going to add TapGestureRecognizers to all of them. </p>
  
  <p>I want to make it so that depending on what image has been clicked, another ViewController will open and display certain information.</p>
  
  <p>For this to happen, I need to know which image has been clicked. How would I do this in Swift?</p>
