This can be useful. I'll be interested in seeing how this gets integrated into the Xcode IDE, as I rarely find the need to go into the CLI, to debug, these days (although I had to, just a couple of days ago, to find a weird Apple crash, but I could work around it).
Within Xcode, you don’t really need it because you’re already running with a debugger when you launch your program.
Yeah, but when the problems go into the API or the Swift Library, things get real murky. The dumps from Xcode can be damn near useless.
