I am having the same issue, I get the same error. I have a list and when this loads, it flashes for a second, then my view get's blank. On iPad it does show up correctly. It's really anoying.

I’m having a simular issue. I have a form, and @FocusState is also not working for me. When I read the value of the focusstate before and after setting the focusstate, its null in both cases. I also thought it was related to the form, but I tried to change it to a VStack, but it was also not working.

Got the same error

I'm having the same issue. To the point where I can't even continue working anymore. When I try to run, my memory start to build up until in need to shut these processes down. Can someone respond to this draft if a fix is found?

For anyone else experiencing this issue, i found a workaround. Use your source control to find the specific part of your code that causes the issue. Then try to look if there is a small mistake in your code. If not, try putting your code on another location (helped for me for some SwiftUI code). i noticed that it looks like the compiler gets stuck on a code mistake, or something like that. I had this issue with part of my code which had no errors at all. Just moving it did the job for me. Keep in mind to keep your Activity Monitor open and keep an eye on the two processes that can build up the memory.

Got a related issue, I think it's a bug. Best to report it via Feedback. Keep in mind your working with beta's ;)
