url is not a file path: {}

Error message

url is not a file path: {}

What it means

Guard in ns_url_to_path: fileSystemRepresentation on the NSURL returned null because the URL does not denote a local file (e.g. http(s): or other scheme), so it has no filesystem path. The message embeds the URL's absoluteString to show the offending input.

Solutions

1. Check the URL scheme (file:/conformant) before attempting path conversion
2. Use NSURL.isFileURL as a precondition
3. At the call site, skip or reject non-file URLs before calling this helper
