Unable to get hidden files

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 `URL`s.

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