Xcode 16.3 DerivedData size problem.

Since Xcode 16.3, the DerivedData folder has doubled in size, growing from 20.65GB to 47.66GB.

This is unacceptable for us because my team frequently builds large apps, and our hard drives will soon run out of space. Otherwise, we would need to clean the DerivedData folder much more often, which also negatively impacts our build times.

When I tried to investigate the source of this increase, I found that the CompilationCache.noindex folder was responsible. However, I didn’t notice any significant difference in incremental or clean build times, to be honest.

Are there any ways to opt out of the feature?
