I have been trying to resolve another warning.
WARNING ITMS-90704: "Missing App Store Icon. iOS Apps must include a 1024x1024px App Store Icon in PNG format. Without providing the icon in the Asset Catalog or via iTunes Connect, apps cannot be submitted for App Review or Beta App Review. Refer to https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/app-icon/ for more information."
Any help would be greatful.
