There's lots of material on the internet talking about how the VoIP background mode capability was deprecated in iOS 10. And yet its still presented as an option in the latest version of Xcode and it still appears in Apple's documentation
https://developer.apple.com/documentation/xcode/configuring-background-execution-modes
The documentation states:
The app provides Voice over IP services and requires automatic launch after system restart. For more information, see the CallKit framework.
It seems apps used to be able to be launched on restart prior to iOS 10, but since then they can't. So is the documentation for this area out of date and wrong?
If its been deprecated for so long, why is it still documented and possible to add it to an application?
