Seems as library has Event API already. API to register event handlers should be added (maybe as dynamic library through command-line arguments) or through some macros in code.

I agree this is something we want to expose as public API eventually.

Tracked internally as rdar://129609023

We have a lot of the moving parts already. What we don't have is a way to hook into the event stream arbitrarily.

Currently, there is support for streaming JSON descriptions of events to an arbitrary file when using swift test. Xcode doesn't offer a way to enable that functionality, but it could be done.

Would that be sufficient for your use case?

Experimental implementation on branch jgrynspan/469-observer-attribute.
