I have used [ios-safari-remote-debug-kit], but it has some issues. Download it,
then in `src`, run `sh generate.sh` to download a WebKit inspector and patch
it, then *in theory* you would be able to just run the start script.

The `start.sh` script as of 77620eb0e has the wrong executable name for
`ios-webkit-debug-proxy`, so this patch is required:

## Screencast to devtools?
[inspect.dev] supports screencasting of the page over USB. I haven't looked
into how they're achieving this, but it is interesting. The WebKit inspector
itself supports screencasting and remote control, but that feature hasn't yet
been made to work with the open source tools.
There's also another project [quicktime_video_hack] which can get the entire
screen of attached iOS devices over USB, but this is not what the debugger
normally uses; however it is likely still quite useful.

# Conclusion
All this software feels quite poorly maintained, and could definitely have some
serious UX polish to work better. It does work, and at least it's probably
going to keep working into the future. The commercial offering is possibly
worthwhile for heavier usage. One thing that's curious about that is that they
have done screencasting over USB, which definitely is possible e.g. with Zoom
on a Mac, but I don't think there are any open source implementations. This
would be useful research.
