  <p>Some images are put on <code>viewControllers</code> in storyboard from <code>Media Library</code> and some programmatically but all of them don't appear on device. I tried unchecking the box on Clears Craphics Context and restarting the simulator but that didn't work. </p>
  
  <p>I tried using the image full name with <code>.png</code> but now I got the image with like this below.</p>

  <p>Are there any other workarounds ?</p>
  
  <p><strong>EDIT: Just to update I was talking about a build on TestFlight that didn't show me any images when I was trying the app. Now I tried erasing all content and settings and connected my mac with device and every image showed up as normal. Can this be problem only with TestFlight or I just solved the problem ?</strong></p>
