There is a question on stackoverflow for that too: https://stackoverflow.com/questions/66143815/xcode-12-5-spm-dependency-cache-location
Xcode 12.5 release notes mention the "per-user-basis" cache for SPM dependencies: https://developer.apple.com/documentation/xcode-release-notes/xcode-12_5-beta-release-notes
Is the location outside of DerivedData folder so cache still persists somewhere in ~/Library/Caches and can be reused even for clean build?
It's very important to know for CI performance!
Any guidance/help is appreciated.
