title: Swift Syntax on |> and .~
body: <p>There is some Swift syntax that I don't understand...</p>
  
  <pre><code>let creator = .template |&gt; User.lens.avatar.small .~ ""
  </code></pre>
  
  <p>Can someone tell me what the <code>|&gt;</code> and <code>.~</code> syntax do?
  I also see <code>%~</code> used.</p>
  
  <p>If you can point out the location in the Swift documentation I would appreciate it. It's been difficult searching using these characters. I would like to see the full array of symbols.</p>
