Just like Ruby, Python can be used for tooling iOS apps. To have instructions regarding this subject would be great!
Python is a great language for checking project consistency as a build phase. For example, at my work we use Python to write a script that we run as a build phase before compiling the code to check if there are assets in storyboards not present in xcassets.
Our setup for python dependencies uses pipenv . This allows us to work with the same version of python and install its dependencies easily, similar to ruby bundler.
