XcodeKit extension cursor position

Question

I am creating for myself Xcode 8 extension with new XcodeKit. I get text with XCSourceTextBuffer and range with XCSourceTextRange. With that I have start and end position of selected text and I can append some text to beginning of the line. The problem is that I can't catch latest position of my cursor, I want to check position of cursor so I can insert text there, not at where my line begins. Does anyone know how to handle that?

Hey, did you ever figure out how to get the cursor position in XcodeKit? – Posner
