Odd, I'm not seeing any problem.

pepejeria commented 4 years ago

Yeah, that is weird. I am also using Catalina 10.15.5 (19F101).

Me too, didn't upgrade to Big Sur. I wonder what is different?

What is the error partially hidden at the top of the console? Is it complaining about finding several versions of the framework? I wonder if it is somehow linking against the wrong SDK?

I don't see that in my build log and who knows if it is related? There's a two year old thread in the forums which mentions it:

Class VCWeakObjectHolder is implemented in both

Not sure what to suggest other than trying the magic incantation to the Xcode gods:

pepejeria commented 4 years ago

Yeah, that didn't work either. I will try again with the next Xcode beta.

kharrison commented 4 years ago

Frustrating. I'll leave this open, maybe someone else is also having the same issue

pepejeria commented 4 years ago

Seems to be fixed in Xcode Version 12.0 beta 3 (12A8169g)
