title: What's the equivalent of finally in Swift
body: <p>I try to use the error handling modeling in Swift2.</p>
  
  <pre><code>do {
      try NSFileManager.defaultManager().removeItemAtPath("path")
  } catch {
      // ...
  } finally {
      // compiler error.
  }
  </code></pre>
  
  <p>But it seems that there is no <code>finally</code> keyword out there.How can I achieve <code>try-catch-finally pattern</code> in Swift.Any help is welcome.</p>
