Same problem. Just got Apple Silicon Mac Mini. IBDesignable button has two red exclamation marks. One thing to do: 1) Delete any tabs showing the IBDesignable item(s). 2) Clean build folder (maybe not needed). 3) Exit Xcode. 4) Restart Xcode/project. This doesn't fix the underlying problem, but you don't have to look at error messages. (Just don't peek at your views :)

Been bugging me too. Discovered when you add a new button it now comes in with style Plain. Change it to "Default" and it warning goes away.

Ran into a segmentation fault. Happened after I was modifying the following line and was not obvious I was missing a last parentheses. let blockW = min(geometry.size.width, 0.7 * (geometry.size.height + 10) Surprising that I couldn't have gotten a friendlier error. This was with XCode 13.4.1. However, when I tried to make a minimal simple program to submit as a bug report, I got useful errors such as: Use of local variable 'blockW' before its declaration. But could turn on/off segmentation problem easily when the statement was in my full app.

I want to add to comments from garthoid about AppleID problems. I ran into problems with errors/warnings disappearing after updating to Xcode 14.3.1 (sorry don't remember previous version I was using). In my case, I had a company ID (personal LLC company - sole developer) that Xcode said had exprired and needed to log in. I don't really remember when/how this ID was created, but there really is no associated login with Apple for it that I am aware of. I deleted the ID. The company is still listed under "Team" on the Accounts tab. However, after deleting that ID, Live Issues started working again. Hope this can be helpful to someone else.
