title: NSLocalizedString with variables Swift
body: <p>I'm trying to figure out how to use NSLocalizedString with variables.</p>
  
  <p>For example, if I want to output "by Peter and Larry", in my <code>Localizable.strings</code> file, should I have the following?</p>
  
  <pre><code>"account.by_user" = "by %@ and %@";
  </code></pre>
  
  <p>How would I call <code>NSLocalizedString("account.by_user", comment: "")</code> with if there are 2 variables <code>name1</code> and <code>name2</code> where <code>name1</code> = Peter and <code>name2</code> = Larry?</p>
