Description

Pipeline.findNearest can now name the result field that holds the calculated distance, matching the Android, iOS, and JavaScript SDKs. The name is a Firestore field name. A dot separates path segments. Omitting it still returns the nearest documents without the number.

On Apple, the pipeline parser was passing that name as a plain string into an SDK parameter that expects a field expression. Every Apple build warned, and a caller that set the name crashed. The parser now wraps the name in a field expression. The macOS parser is a symlink to the iOS file.

Android was ignoring the name. It now passes it to FindNearestOptions.withDistanceField. Web already copied the name through.
