iOS App displayed with grey icon in Testflight

Deploying my iOS application to Testflight results in a grey-ish app icon.

All the icons are PNG files saved without transparency. In XCode 9.0 everything looks fine: Icons as seen in XCode

In iTunes Connect the app icons seems to have the right color: Icons as seen in iTunes Connect

Yet Testflight displays a greyish version of the icon: enter image description here

The app icon on the home screen looks fine too.

It's the first time I stumpled upon this issue.

Solution

  • We tried different color profiles, web tools, nothing worked. Then we added red and green numbers to our icons to find out which of the image files was used for the generation of the app icon in Testflight – and suddently the problem disappeared.

    As strange as that sounds but adding a magenta dot in the corner of the icon solved the problem.
