This site aims to be a collection of ready-to-copy shell script snippets covering common build-related tasks for the iOS and macOS projects.
Xcode comes with a set of command-line utilities that can be used to automate app build and distribution. Fastlane is a great tool for build-related automations but sometimes you just need one quick command or are curios about what happens under the hood.
Each time I need to do something like that I spend some time to search for a solution. At some point I decided to start logging this in a structured for for further reference.
Some use case are not yet covered here and I will try adding those I encounter. The site is open-source, feel free to fork and sumbmit PRs for workflows you are using!
