Collection of Frida scripts that turned out to be helpful for reverse-engineering :) The goal of these scripts is to be rather generic and provide you with insights about larger closed-source projects.
-
libdispatch.js hooks iOS Grand Central Dispatch (GCD). This is useful to show thread creation. When printing a backtrace, you can even get an idea of the overall program flow. Prints might be out of order on high load, i.e., when attaching it to
CommCenter, but it works quite well. Tested on iOS 13.3-14.4. -
mach_msg.js hooks iOS Mach messages. Almost everything is a Mach message on iOS, from Cross-Process Communication (XPC) to IOKit driver calls in the kernel. Might be a bit verbose, tunable via two parameters to truncate messages and skip XPC. Tested on iOS 13.3-14.4.

iotracy.js hooks IOKit. External repo, not included here, by robre.
