Strangely I was getting this tonight all of a sudden and I did NOT have a certificate with a + on it. I'd had this problem before with the + and this solved it as above. But tonight there was no plus. I had been switching between Xcode 13.4.2 and Xcode 14.2 and maybe something got messed up. To fix I did two things: toggled my cert to + and back and restarted Keychain Access. One of the two fixed it for me and I could build again.

Is it enough to add the Communications Notification capability in Xcode to use this or does one need to donate actual message or call intents? Our app for medical providers could use access to the Focus Status, we believe, but our model does not lend itself well, at this time, to actually donating the intents and using Communications Notifications. We are still working through what it all means. Thanks.
