I'm just curious, if I was to run my application on a linux server.

How would I ever know what caused the crash?

when I compile using `swiftc main.swift` and run with `./main`, the error seems even more useless.

all I get is:

    Swift/ContiguousArrayBuffer.swift:600: Fatal error: Index out of range
    zsh: illegal hardware instruction  ./main

I don't know, I write Swift on a Mac targeting macOS or iOS. I usually have Xcode open to build/run/debug and for documentation lookup, and alternate between that and VSCode for actually writing the code; worst thing about Xcode for me is the find-replace, that's probably the biggest reason I keep VSCode open.
