PyObjC is a bridge between Python and Objective-C. It allows Python scripts to use and extend existing Objective-C class libraries; most importantly the Cocoa libraries by Apple.

You can ignore this package and remove it from the requirements.txt without leaving behind a empty line in the file.
Make sure you put your keys in environment variables.
