I'v been trying to upload a build of an app that has been on the AppStore for years, and every time I do, I get the following error.
[Transporter Error Output]: ERROR ITMS-90704: "Missing App Icon. An app icon measuring 1024 by 1024 pixels in PNG format must be included in the Asset Catalog of apps built for iOS, iPadOS, or watchOS. Without this icon, apps cannot be submitted for review. For details, see https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/app-icon/."
The message is clear but I think it is wrong, since I have had the current Assets Catalog in place for more than 3 years and never had issues before. I also have completely replaced it for a new one in the attempt of fixing some weird issue on the project / catalog side.
The icon that is mentioned is there, as a RGB, Non Alpha PNG.
The only big change done lately to the project, beside moving to xCode 12, is the support for Catalyst. I think it might be related to it, but I'm completely clueless on how.
I'v also checked the Assets.car on the ipa and, despite not finding the icon there by itself, i find some images that are groups of the icon in different sizes... not sure of what to think of it :)
