Xcode and HTML
can I modify Xcode so that I can have an HTML template and have autofilling HTML code? trying to learn

Why not just use Sublime Text 3, or Textastic (Mac App Store), both of which integrate Emmet within their products, and understand the Emmet shortcuts to expand HTML and CSS constructs in code? I believe that is as close to auto-filling HTML code as you are going to get.
You will find that Apple never built Xcode to save you time with HTML code.
