title: iOS - git doesn't recognize Localizable.strings file to commit
body: <p>I work with:</p>
  
  <p>OS X El Capitan 10.11.5</p>
  
  <p>XCode 8.2.1</p>
  
  <p>Swift 3.0</p>
  
  <p>I have two <strong>Localizable.strings</strong> files (English and Spanish) in my project that work perfect. 
  This files are in their respective folders:</p>
  
  <ul>
  <li>en.lproj</li>
  <li>es.lproj</li>
  </ul>
  
  <p>For some reason <strong>git doesn't recognize these two Localizable.strings</strong> files when I commit changes in my project. </p>
  
  <p>I made a test changing the extension from *.strings to *.txt and it was recognized instantly by git as a change available to be commited.</p>
  
  <p>I tried some "solutions" I found but they don't work at all:</p>
  
  <ol>
  <li>Added a file named <code>.gitattributes</code> with the following text in it:  <code>*.strings diff=localizablestrings</code></li>
  <li>In the file <code>config</code> in the folder <code>.git</code> I added the following code: </li>
  </ol>
  
  <p><code>[diff "localizablestrings"]
  textconv = "iconv -f utf-16 -t utf-8"</code></p>
  
  <p>Nothing made git recognize my Localizable.strings. May you please help me find what am I missing? Thank you.</p>
