I know this is an old post, but, my crash logs are not being symbolicated in Device Logs.
Here is the un-symbolicated report I'm seeing from a crash I induced in my watchApp:

The addresses in lines 2,3,4,5 relate to my code, but are not symbolicated. Locating the source code line is a nightmare!

Configuration:
iMac 27" , iPhone6, Apple Watch 2
I have raised a Bug Report, but thought I would post here to see if anyone else is has a solution.
