DevCleaner 2.6 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally produced by Konrad Kołakowski. We recommend checking the downloaded files with any free antivirus. The software lies within System Tools, more precisely System Optimization.
From the developer:
DevCleaner helps you reclaim tens of gigabytes of your storage used for various Xcode caches. Since most of those cached files and symbols are not reclaimed over time and could consume a large amount of your storage, a cleaning tool like DevCleaner can help you free up valuable disk space.
