If you want to reclaim tens of gigabytes of your storage used for various Xcode caches - this tool is for you!
Xcode could store tens of gigabytes in ~/Library/Developer folder. Most of those cached files & symbols are not reclaimed over time and could consume a large amount of your storage, which is especially important if you have relatively small SSD drive.
DevCleaner gives you an easy way to inspect auto-generated files and clean them if necessary. It could also remind you about scan after a while.
It includes command line tool that allows you to include cleaning in your scripts.
