Swift Trimming String : <p>I am trying to trim a string so that i am left with everything on the right side of a colon in Swift.</p>

<p>For example</p>

<blockquote>
  <p>"Sally: Hello My Name is Sally"</p>
</blockquote>

<p>Becomes</p>

<blockquote>
  <p>"Hello My Name is Sally"</p>
</blockquote>

<p>What would the trim function be?</p>
