title: How to set Cursor in TextField
body: <p>My ViewController contains a TextField. How can you make the Cursor go to the TextField ?</p>
  
  <p>I am thinking of a method similar to this - but what to add for the Cursor to jump into the TextField allowing the user to start typing whenever this method is called ??</p>
  
  <pre><code>func reloadEntries() {
      self.txtfield?.becomeFirstResponder()
      ...
  }
  </code></pre>
