问题
So today while opening Xcode (Version 10.1 (10B61)) it installed some additional packages (unfortunately I don't know what). Then when it came to opening anything (existing project, creating a new project, creating playground) it crashed with error as posted below.
I tried reinstalling Xcode, but the same error occurred. I'm using MacOS Mojave (version 10.14 (18A314k))
And finally an error:
