The Badge plugin for Fastlane allows you to offer version numbers, release type, etc.
On the MacOS collector, install the dependencies:
brew install librsvg brew install imagemagick brew install graphicsmagick
Add a line to the project Gemfile:
gem 'fastlane-plugin-badge'
Add a block related to the badge to Fastfile and add the version number via a variable.
jenkinsVersionNumber = ENV["APP_VERSION"] ... lane :adhoc do add_badge( alpha: true, dark: true, shield: "Version-#{jenkinsVersionNumber}-orange", grayscale: true ) ... end
