title: Impossible to load an image in xcassets on bundle
body: <p>I need to include images in a static library. 
  I created a bundle and inserted in my images, the problem is that it seems to work if I include the images directly in the bundle, but stops working if I put in a xcassets file. </p>
  
  <p>I followed many guides and searched for a solution on this site. 
  The most popular solution is to insert this line of code: </p>
  
  <pre><code>[UIImage imageNamed:@"MyBundle.bundle/imageName"] 
  </code></pre>
  
  <p>but it seems not work for me </p>
  
  <p>any ideas?</p>
