Prototype for #133465

Note: lldb does not receive logs. Maybe there's a command to do that?

Alternatively, you can get logs via devicectl with this command (the key pieces being OS_ACTIVITY_DT_MODE and --console:

xcrun devicectl device process launch --device 00000000-0000000 --start-stopped --environment-variables '{"OS_ACTIVITY_DT_MODE": "enable"}' --console com.example.vanilla --enable-dart-profiling

However, using --console leaves the launch process running, so it doesn't print the results of what process was started.

This could be resolved by getting the processes using devicectl

xcrun devicectl device info processes --device 00000000-0000000 --json-output /path/to/a/file/processes.json

And matching the executable against the installationURL from the devicectl device install app command.
