Hi lehrian... Unfortunately I'm not a DTS Engineer so I have no solution. But just to say I downloaded your sample project and I do see the same flurry of constraint warnings but the CSV file is displayed. I was going to do this myself to submit a bug report so you saved me the work:-) Lets hope there is some feedback soon

Ive tried this now with Ventura 13.0.1 on same M1 Mac and still same There were no VoIP Pushes to start an incoming call. I am getting notifications for missed calls etc but no VoIP Pushes Callkit does not seem to work so I get no Audio. It is never activated... However rather strangely when I start an outgoing call the Mac Opens the FaceTime App! Anybody having similar experiences with iOS VoiP Apps on M1 Macs?

Yes i see it is still happening with released Xcode 14.0
