You can add a visionOS Platform in App Store Connect. But then if you want to submit for that platform, you'd have to submit a visionOS binary, not one for 'visionOS (designed for iPad)'. To do that, go to your build settings and under Architectures, set Base SDK to 'visionOS'. Then you will see the Destination 'Any visionOS Device (arm64)' in Xcode. If you keep the Base SDK as 'iOS' and submit a binary, it will be sent to your iOS app Platform. It won't be seen by a visionOS Platform.
