No, they just closed my bug, and I felt unable to release on catalyst :(
Recently I see they have updated the documentation for this call
https://developer.apple.com/documentation/messageui/mfmailcomposeviewcontroller/1616887-setbccrecipients with a note to say it doesn't work under Catalyst.
Annoyingly it ALSO doesn't work when running the iOS app on Apple Silicon. Which I see as a much more serious problem.
I believe being unable to put contacts into Bcc compromises email address privacy, and they really should fix this, rather than just documenting it. Please report this as a bug to them- as the more developers that do this, the more likely it will get fixed.
Your fix makes group a CNGroup instead of a CNMutableGroup, although why that should help I am not sure

I'm seeing the same as I work my way through a series of tutorials.
I have to assume its a bug in SwiftUI?

I assume you asked them to send a screenshot?They do also need to have EITHER a message title, or some new message text (not just their signature) for the send option to become available
In case this helps anyone else, note that the format is of the form "group.DEVELOPER ID.maccatalyst.APP ID"If your developer ID is ABCDEFG then you typically need to add the app group "group.ABCDEFG.maccatalyst.com.yourcompanyname.yourappname" on the certificates website.This took me DAYS to work out, due to a not-particularly helpful error message.Also you need to be using modern URL-based methods to load and save files, the one my iOS app used was deprecated.

From most of my users (I wrote a group email app) this happens when they do not have an email account set up for iOS (on the Passwords and Accounts page of the Settings app.)Typically this is because they use a proprietary app to access email, such as the Gmail or Yahoo app. They use their own settings.It will also happen if they delete the Mail app from their device, again because they are using something else.
