The built-in debugger is developed directly by the V8/Chromium team and provides certain advanced features (e.g. long/async stack traces) that are too difficult to implement in Node Inspector.

XCGLogger - A debug log framework for use in Swift projects

XCGLogger is the original debug log module for use in Swift projects. Swift does not include a C preprocessor so developers are unable to use the debug log #define macros they would use in Objective-C. This means our traditional way of generating nice debug logs no longer works. Resorting to just plain old print calls means you lose a lot of helpful information, or requires you to type a lot more code.
