title: Edit html code from UIWebView swift
body: <p>I am presenting a WebView in my app, however, there are some modifications I would like to make on the website I am presenting. If I load google.com, for example, I might want to change the text of the "google search" button. How do I go about doing this?</p>
  
  <p>The similar questions asked are all in Objective C and do not seem to be working.
  Thank you in advance.</p>
