Xcode 13.3 An internal error occurred editing functionality may be limited

This happens to me sometimes. What I do is:

1. Quit Xcode.
2. Reload Xcode and the project.

If it happens again, do 1 and 2 above, reboot the computer, and try again.

Hope this helps, Dan Uff

Have you solved it? I reinstalled xcode, it still fails

I had the same problem after updating my mac to 14.3.1.

I found I only got this black screen when trying to use the iPhone 15 simulator or the iPhone 15 (including Pro and/or max) layout.

If I used the iPhone 13 or others, I could adjust the layout and it would work on the simulator, however, the error remained.

I deleted the iPhone 15 Simulators and then the error went away too.
