Unable to get hidden files

[CraigSiemens]

I've got a script where I'm trying to work with a hidden .swiftlint.yml file. As far as I can tell Files doesn't allow working with hidden files, it always shows a missing error when trying to access one. Is that correct or am I missing something?

My current work around is to use URLs.

let fileURL = folder
    .url
    .appendingPathComponent(".swiftlint.yml")
