Also having the same issue, still. Would love to know a solution on this, as I'd like to migrate to M1s in our CI pipeline but inconsistent tests across architectures is a major blocker.

Wow this is great news - seeing coverage now. Unfortunately, this has broken tests I have with StoreKitTest framework :(

Still happening, and still no movement on my bug report. FB9088539 I'd like to start migrating my build nodes to M1 Mac minis, but without code coverage generation it grinds our build process to a halt.
