I also have this Assert in the log. I also have a problem with the view that I am troubleshooting. I guess we just ignore it for now?

I'd like to the known the answer to this also. I end up deleting DerivedData 5 to 10 times per day on a a large project. Often I get corrupted database error, but just rebuilding again seems to fix it.

I am having the a similar problem, any solution.
