title: Xcode 6.1 Warning about Launch Image in Asset Catalog
body: <p>I am using Xcode 6.1 to create a app supporting iOS 6 and later.</p>
  
  <p>.In target's "App Icons and Launch Images", I set the Launch Images Source as "Use Asset Catalog" and  Launch Screen File to "LaunchScreen".</p>
  
  <p>In Images.xcassets which created by Xcode, I fill in every box for "LaunchImage", but there's always a warning message:</p>
  
  <blockquote>
    <p>Retina 4-inch Support. Applications using Launch Screen Files and
    targeting iOS 7.1 and earlier need to also include a Launch Image in
    an Asset Catalog.</p>
  </blockquote>
  
  <p>I created another Image Set named as "Default" and fill in the "Retina 4 2x" box with expected image. But the warning message still there. </p>
  
  <p>Any hint to clear this warning? Thanks.</p>
