Notes on debugging on the Swift compiler

Invoking lldb

  • swiftc invokes sub-commands, so you shouldn't run lldb on the swiftc command itself. You can add the -### option to swiftc to see the underlying sub-commands. Pick the correct sub-command, then run lldb -- <command>.

  • Usually, we want the first command, so run something like:

    lldb -- `swiftc file.swift | head -n 1`

  • Use --one-line r to run immediately after loading, without having to set breakopints - great for debugging crashes

I was looking at the console log (console_log_ISSUE-START_2025-04-14_14-04-45.txt), looking for causes why the data packet failed to send.
