A KobaSWD Cable

The KobaSWD is a JTAG/SWD Cable capable of debugging CPFM 00 or 01 devices with a A14 or newer which have the Lightning port, using software called Astris. It can be connected to another SWD debugger, using the SWD port (shown on the bottom middle of the probe), and it can also do UART/Serial. They can be purchased from obscure markets. The cable appears to be a newer version of the Kanzi Cable.
