Xcode8 - successful build falsely reports errors, then immediately removes them

Originator:markd

Product:Developer Tools Product Version:Version 8.0 beta 3 (8S174q)
Classification:Usability/UI Reproducible:Sometimes
 
Summary:
See attached movie.  I edited some code. It was correct.  Did a build. Xcode reported an error flag on the line I edited. Then it reported an error up in the status LED.  And then it took the errors away after a couple of seconds. 

"oh no you have an error!" "oh crap what did I do wrong this time"  "ha ha just a joke"  ">:-("

Attached is the project - a brand new Xcode8b3 created project, FWIW.

Actual Results:


Version:
Version 8.0 beta 3 (8S174q)
10.11.5 (15F34)


Notes:
It's really not that big a deal - just burn some time and wait for mysterious errors to go away, but
when these kinds of things happen day-in, day-out, it's just another heavy-sigh
death-of-a-thousand-cuts that makes using Xcode unpleasant.
