XCGLogger
A debug log framework for use in Swift projects. Allows you to log details to the console (and optionally a file), just like you would have with NSLog or println, but with additional information, such as the date, function name, filename and line number.
XCGLogger has been used in over 15,000 apps made by companies such as Twitter, PlayStation, Firefox, LeapFrog, The Wall Street Journal, A&E Networks, Sky News, and more.
Watchdog for Xcode
A simple to use developer utility that monitors Xcode and automatically cleans up stale cache files that prevent developers from getting a good build. It saves developers hours of aggravation dealing with a number of problems.
Watchdog runs in the background, monitoring Xcode and keeping its cache files under control. Developers can trigger a manual clean at any time or customize automatic cleans using four configurable settings.
