title: Xcode10 Validating: No transparencies in my images but still not accepting?
body: <p>Everything was OK on previews versions   and  I am 100% sure that all my images and icons (icon-1024.png included) has no "transparencies" plus has no "alpha channels" also, </p>
  
  <p>Then, I am trying to validate my APK by the menu "Organizer" BUT, getting the same error message:</p>
  
  <blockquote>
    <p>Invalid App Store Icon.<br>
    The App Store Icon in the asset catalog in 'nonono.app' cant be transparent nor contain an alpha channel.</p>
  </blockquote>
  
  <p>The tools I used to adjust my images:</p>
  
  <pre><code>https://appiconmaker.co,
  https://makeappicon.com     
  and 
  mogrify -alpha off res/icon/ios/*.png
  </code></pre>

    <p>and 
    another from xcode:</p>
