We started off using those convenience APIs from SourceKitten (huge thanks for SourceKitten, BTW) but ended up moving to our own solution — for this issue due to some performance issues, particularly in large files, and for interfacing with SourceKit in general because we wanted a little more control over request/response handling.

It's MIT-licensed so feel free to grab the String extensions from the project yourself: https://github.com/jpsim/SourceKitten/blob/master/Source/SourceKittenFramework/String+SourceKitten.swift

SourceKit, however, deals in terms of integer offsets and lengths (UTF-8 code units?). Is there a more efficient or easier way to convert back and forth between the two other than doing the index(_:offsetBy:) -> samePosition(in:) dance?
