I was reading that this crash is likely due to a incorrect variable assignment, does that align with this output? If so, how can I determine where/what variable is being assigned? Or where should I be looking instead? I've been unable to reproduce the crash so far.

This backtrace indicates that something has gone wrong deep in the Swift runtime. It’s hard to say what might be causing that without more details. Please post a full Apple crash report. See Posting a Crash Report.

Annoyingly, the moderators deleted the posts containing your crash reports )-: I’m unable to un-delete them (r. 115104682), but I was able to recover a crash report.

Was that an Apple crash report? It kinda looks like one, but there’s some stuff in there that’s not quite right.

Oh, hey, the DevForums admins gave me a workaround for that, so I’ve un-deleted your crash report post.

Well, we left off with me trying to get an Apple crash report for the failure. Do you have one of those? If so, please post it here, using the instructions in Posting a Crash Report.
