rvictl not working on big sur and ios 14 beta 3

I'm trying to inspect network traffic on an iphone 11 pro, I use:

rvictl -s [UDID]

on terminal and it closes after a couple seconds without any error. I know the UDID is correct because if I use a wrong one it brings up the help . I installed most of the extra tools I found for xcode and such and rvictl is available, it just doesnt work.

This issue (81125115) was fixed in Xcode 13.0 (13A233).

Disabling SIP as a workaround is no longer needed, so I recommend enabling SIP (check with csrutil status).

For Apple Silicon Macs, the Reduced Security policy "Allow user management of kernel extensions from identified developers" is still needed, instructions here.
