The description of Watchdog for Xcode - Play With New Friends
An App to Eliminate Stale Cache FilesWatchdog for Xcode is a tool that automatically clears old cache files that are mitigating a good build. The program would save you hours that could have been otherwise spent on dealing with old images, continuously growing DerivedData folder, constants/defines failing to update after being changed in the code, unseen localization file changes, phantom breakpoints, Xcode not running a build on the device, etc. With Watchdog, you need not clean build, exit Xcode, reboot your Mac, etc. just for fixing a stubborn bug.
