title: Export app for localization not including strings created with NSLocalizedString in Xcode 6 Xliff
body: <p>I'm trying to localize my app, and I have the following code:</p>
  
  <pre><code>self.arrayLabels = [NSArray arrayWithObjects:NSLocalizedString(@"This is a test", "this is a test"),  NSLocalizedString(@"I want my strings to get added to localizable strings file", "strings comment") , nil];
  </code></pre>
  
  <p>So, basically, from what I understand, this should be it, I click <code>Editor &gt; Export for Localization</code> and the strings should be there on my <code>XLiff</code> file. But, they aren't. </p>
  
  <p>I have two languages, english and portuguese, both <code>localizable.strings</code> files are empty. </p>
  
  <p>Am I missing something?</p>
