body: <p>What gesture can execute code only while user placing their finger on the screen?</p>
  
  <p>Running certain code should not be Effect of the Cause(gesture), what I want is running certain code while user holding their finger on the screen, and if the user took their finger off the code stops running</p>
  
  <p>For example, </p>
  
  <pre><code>//some view
  .unknownGesture{
  // running this code only while user placing their finger on the screen
  }
  </code></pre>
