Xcode Storyboard is black (An internal error occurred)

Question

I have a big problem. Since two days Xcode only shows the Storyboards in black like shown below. As you can imagine it is terrible for me as i can not work with the background blacked out.

The error that is shown is "An internal error occurred. Editing functionality may be limited."

Below you can see the Log.txt with the error

I already tried to

update Mac Software
Update Xcode
Clean Project
Close Xcode
Restart Mac
set derived Data in Preferences > Locations to Default

The You can see the black screen here

It would be very nice if you can help me to solve this.

Thank you very much

There are lots of "the storyboard is black" question/answer pairs on stack overflow already. There is no point asking this again. — matt, Feb 01 '21 at 21:09
thanks. That also didn't help. I'm using the MacBook Pro with an M1 (2020) and "Open using Rosetta" is checked. I cleaned the project, closed Xcode, restarted the Mac, still nothing has changed. — , Feb 02 '21 at 20:21

Update: This issue fixed with Xcode 12.5 release

I got this same error today and I tried the ways that you mentioned, but none of them worked. And then I remembered that I checked "Open using Rosetta" in Xcode's "Get Info". When I unchecked this option, cleaned the project, and reopened Xcode, it works.

If you are using MB with an M1 chip, I think you can try this.

But I should warn you if you unchecked "Open using Rosetta" option, you can get "IPA processing failed" error when you achieve the project. More detail: How to fix "IPA processing failed" in Xcode 12.2 with MAC M1

Well, that helped me too.However Disabling Rosetta mode will fail your build also. That's so unfortunate. – Anand Feb 03 '21 at 05:12

This was the only working method, thank you very much. "cleaned the project, and reopened Xcode" is important. – wonder Feb 25 '21 at 10:27
