Diskzy vs DevCleaner for Xcode: an honest comparison
DevCleaner for Xcode is a focused tool for one job: inspecting and cleaning the files Xcode generates in ~/Library/Developer, such as derived data, device support files, old logs and the documentation cache. It is free on the Mac App Store with optional tips, includes a command line tool for use in scripts, and its App Store listing says it requires macOS 14 or later and collects no data.
Diskzy covers the same Xcode folders as part of a wider cleanup, with a stated rule for each: DerivedData is ticked unless Xcode is open, the two newest DeviceSupport versions are kept, Archives are listed but unticked. It then goes beyond Xcode to project build folders, package-manager caches, other apps' caches and logs, and adds a disk map, a System Data breakdown and an uninstaller. It is a paid app.
