I am working with Xcode 9.2
I got this error message :
"Invalid App Store Icon. The App Store Icon in the asset catalog in 'abc.app' can't be transparent nor contain an alpha channel."
when "validating" the app before it can be uploaded to iTunes.
Yes my Icons are transparent and have alpha chanel.
This was always coorect when working with Xcode 8 on the update before in 2014.
Did it change in Xcode 9? or did any thing esle change?
Do I have to re-design all app icons?
