Still constantly crash down, with no solution in sight.

I've uploaded crash reports multiple times already, and now Xcode occasionally crashes upon opening. I've tried reinstalling Xcode, installing Git, and deleting the user data directory, but none of these have worked.

Thank you very much. I will check this part of the code. Meanwhile, I want to ask, if I use SiriKit, it won't be possible to have my shortcuts appear in the Shortcuts app home page, right? look forward for you reply.

How cloud I catch the error that accurately perform incremental updates failed?
