Bug? Icon 1024

[Emme Developer]

It's not a very bug or issue, but i would like to report it.
As explained in tutorial:

The file name should be icon-store-1024.png (all lowercase) and its size should be 1024x1024.

This create a set of icon png with tranparence. When i tried to send the application on store, i got this error

ERROR ITMS-90717: "Invalid App Store Icon. The App Store Icon in the asset catalog in 'Some.app' can't be transparent nor contain an alpha channel."

I solved the error by saving the icon in jpg (with no Alpha channel so) and putting the new icon in project (using xcode)

I don't see a bug here... You need to use a non-transparent icon for the large icon. The generated icons will be non-transparent as well.

The generated icons will be non-transparent as well.

But if i use a png with transparent channel (can i remove the Alpha from a png? I don't know) then the IDE will make a set of icons with Alpha channel. Is not easier make a set of jpg?

It will be accepted with a non-transparent PNG file. Note that you can use a jpg file and only change the extension to png.

For something I use the application XnView and convert the image in 24bit color.
