This seems like a duplicate of #1385 to me.

@MaxDesiatov There was a build script issue that is not related to Xcode12. Please see the patch 9a99563

[MaxDesiatov]

Awesome, many thanks for resolving it! I'll try to submit the patch upstream.

@kateinoigakukun unless you'd like to submit the patch yourself 🙂

@MaxDesiatov It would be really helpful for me if you can submit 🙏

[MaxDesiatov]

No problem at all, will do 👍
