Hello,
After doing a recording with Time Profiler, we know that the xctrace file should already contain all the symbols (and if it doesn't xctrace symbolicate can be used), as the symbols are shown on the Instrument GUI. However we have not found a way to have access to them.
This is a very similar question to How can I symbolicate addresses from xctrace run which was unfortunately left unaddressed.
Finding how to solve this issue would greatly benefits to instruments-to-gecko used at Snap.
Regards,
