I just switched to React Native from React and followed instructions on official site for creating and initialization project. I'm not using Expo, created project with npx and typescript template. When I opened project there was ruby-version and Gemfile files inside. I cannot find any documentation on website about Gemfile and why is ruby necessary in project creation, anyone got some more info or some docs that I missed on site? Thanks.

Your simple answer is for iOS Development.

Using react native we can do iOS development. So, for ios we need cocoapods, for using cocoapods we need ruby and this Gemfile over there.
