Summary:
I'm adding an extension to Array, scoped by String.  I had the syntax wrong.  Xcode said "hey, there's an error" but no indication in the editor that anything was wrong. In fact, the only indication was the teeny-tiny little icon in the top bar (which I generally ignore - it's just flickering noise most of the time)

I click on the error, and it takes me to the build like with a message "<unknown>:0: error: type 'Element' constrained to non-protocol type 'String'", no indication of where the problem is.  Luckily this is a small project so I know where to look

video and screen shot attached. Project attached.

Steps to Reproduce:
1.  Extend Array, limited to arrays of strings, and get the syntax wrong
2. Get an error

Expected Results:
3. Xcode shows where the error is 

Actual Results:
4. Get shuffled to the build log with no indication where the problem is

Version:
Version 8.0 beta (8S128d)
10.11.4 (15E65)


Notes:
It's really not that big a deal - just grovel around in the build log, but
when it happens day-in, day-out, it's just another heavy-sigh
death-of-a-thousand-cuts that makes using Xcode unpleasant.



Configuration:
Happened often in Xcode 7 too.
