The thing with file reference URLs degrading to file path URLs is in the Swift is actually not a bug, it’s deliberate (https://bugs.swift.org/browse/SR-2728 <https://bugs.swift.org/browse/SR-2728>). The Swift team decided that file reference URLs are not appropriate for the Swift URL value type. However, if you’re using Objective-C, file reference URLs will still work fine, and you can always make an Objective-C wrapper that stores a file reference URL and use that from Swift.
