title: How to swipe back in Xamarin.iOS?
body: <p>I have a ContentPage with a WebView in my shared Xamarin project. </p>
  
  <p>To enable Android's back button within the WebView, I used the following code:</p>
  
  <pre><code>protected override bool OnBackButtonPressed()
  {
        _myWebView.GoBack();
        return true;
  }
  </code></pre>
  
  <p>As we all know, iOS does not have a back button. I want to enable swiping left in order to navigate to the previous Webview page.</p>
  
  <p>What is the easiest way or approach?</p>
