Open Radar

 
Summary:
I have an objective-C method I've declared but doesn't have a backing implementations (happens during cleanup)

I get a warning:
/Users/markd/[redacted]:56:17: Method definition for 'yPositionsForAllEventsFrom:toEventEnd:' not found

And a tantalizing message:
/Users/markd/[redacted]:146:1: Method 'yPositionsForAllEventsFrom:toEventEnd:' declared here

When I click there, it takes me to the header file scrolled to the top, rather than the actual place that's indicated in the tantalizing message.  Line 146 is the correct location.

See movie at this dropbox link: https://www.dropbox.com/s/[redacted]/missing-method-formation.mp4?dl=0

Steps to Reproduce:
Have a clean building objc class.
Take out the implementation of a method declared in the header
build
get a warning about missing implementation
click on the "Method 'allyour:Base:' declared here" thingie in the issues inspector

Expected Results:
got to where the legacy method declaration lives

Observed Results:
just go to the top of the file

Version:
Version 9.0 beta 2 (9M137d)
10.12.5 (16F73)

Notes:


Configuration:
Works fine in Xcode8 IIRC.  This is a rarity for me doing objective-C inside of Xcode. I usually use another editor for that.
