Why doesn’t deinit support async? At the end of a test, I want to wipe data from HealthKit, and it’s delete function is asynchronous.

Why doesn’t deinit support async?

Asynchronous deinitialers are an ongoing topic of conversation on Swift Evolution. The specific proposal was SE-0371 Isolated synchronous deinit, and you can follow links from there to the various discussion threads.

Depending on your specific goals, there may be ways around this. One option is to kick off a new task to do the clean up, and then not wait for it before returning from your deinitialiser.
