Can you give an update on this, @jeremyhu? i.e. if and when IOS development will be supported. Is there an official statement on this? The whole point for us is to be able to port our IOS apps to native Mac, (a single codebase where we can), and not having half of that Dev environment is going to be *really* limiting.

To pour more fire on this flame, yes, this is 100% reproducible in Big Sur 11.6. Plugged into Caldigit hub with external monitor via displayport. Cycling the power a few times on the hub will trigger it. Or waiting for the laptop to sleep overnight. I've been sending crashdumps every night for a week, if anyone at Apple feels like looking into it.
