Thanks! But what can I do if I don't have a device running that particular version of iOS? Am I out of luck?

I've been having this same issue with almost all of my state with no way of fixing it except displaying the state in the view (which is far from ideal)! I've sent in a bug report with Feedback Assistant and I suggest you do the same!

Seems at this point to be a bug with Xcode 12 and the new framework. I was able to work around the issue by displaying the value of assignment in a View. I added the following code between lines 8 and 9 which fixed the issue and had the value updating properly: Text("\(assignment?.description ?? "")" .hidden() I've sent in a bug report (FB7823148) through Feedback Assistant.
