There is no documentation for running, debugging and testing system extensions on iPadOS16. The WWDC 2022 session "Bring your driver to iPad with DriverKit" does not count because (as of beta 2) it is completely unreproducible.
This document tells us that to test our system extensions we must disable SIP so it's clearly only for macOS: https://developer.apple.com/documentation/driverkit/debugging_and_testing_system_extensions
It would be nice if this document were updated with reproducible instructions for testing system extensions on iPadOS!
