The RPi Foundation provides a few options for doing SWD debugging on the 

1) An customized OpenOCD running on a standard Raspberry Pi board that 
uses GPIO to implement an SWD interface.

2) An installable binary for the RPi Pico devboard which turns it into a 
USB <> SWD adapter that works with a customized build of OpenOCD.

Installing, wiring and using these is well described in the RPi Pico 
documentation and the user experience is very similar to debugging with 
ST-Link on an STM32.
