Hi there!
I'm really inspired by possibilities of the new instrument architecture that were presented during the last WWDC. Unfortunately, the demo application wasn't released, so I tried to reproduce it by myself.
I created a project to research how new instruments might be built above signpost functionality. To my surprise, it doesn't work for me in any configuration when I'm trying to use a os-signpost-interval-schema with message pattern both for start and end tags. However, it works with a raw-message. Could you, please, help me to figure out, what is the problem here? Am I doing something wrong, or it's a bug in Instruments?

Documentation I used: https://help.apple.com/instruments/developer/mac/current/#/devcd5016d31
Sincerely,
Alex
