I recently started programming native addons but couldn’t find how to debug them easily. After couple nights, I found very easy solution described below.

To debug native addons generate an xcode project file. From the root of your project (where binding.gyp lives) run:

This will create ./build/binding.xcodeproj folder, which you can open:

Once project is opened, make sure to configure the scheme. Open Product -> Scheme -> Edit Scheme, and then:

1. Select Info -> Executable -> Other and enter path to node executable
2. Select Arguments and enter full path to the javascript file which invokes native addon.
