I just made a mac catalyst app and the Bundle Id shown in Xcode is "maccatalyst.com.xxx.xxx".
However I cannot register a Bundle Id in the App Store Connect with the same name.
I tried several times and find the problem might be Bundle Id cannot be start with "maccatalyst".
In this situation, I cannot upload the app build to App Store Connect because the Bundle Id is mismatched.
Is there any way to solve it?
Found the solution by my self.
Go to the Certificates, Identifiers & Profiles page, click your identifier of your iOS app. Check "Mac" from the Capabilities. The Bundle Id is then created on the App Store Connect side.
Once you click on the Mac capabilities, do you need to re-upload the iOS app or anything special?
