fastlane is the easiest way to automate beta deployments and releases for your iOS and Android apps. 🚀 It handles all tedious tasks, like generating screenshots, dealing with code signing, and releasing your application.

You can start by creating a Fastfile file in your repository, here’s one that defines your beta or App Store release process:

lane :beta do
  increment_build_number
  build_app
  upload_to_testflight
end

lane :release do
  capture_screenshots
  build_app
  upload_to_app_store       # Upload the screenshots and the binary to iTunes
  slack                     # Let your team-mates know the new version is live
end

You just defined 2 different lanes, one for beta deployment, one for App Store. To release your app in the App Store, all you have to do is

fastlane release

Getting Started

Installing fastlane

fastlane can be installed multiple ways. The preferred method is with Bundler. fastlane can also be installed directly through with Homebrew (if on macOS). It is possible to use macOS's system Ruby but it's not recommended as it can be hard to manage dependencies and cause conflicts.

Managed Ruby environment + Bundler (macOS/Linux/Windows)

Ruby

If you use macOS, system Ruby is not recommended. There is a variety of ways to install Ruby without having to modify your system environment. For macOS and Linux, rbenv is one of the most popular ways to manage your Ruby environment.

fastlane supports Ruby versions 2.4 through 2.7. Verify which Ruby version you're using:

$ ruby --version
ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin19]

Bundler

It is recommended that you use Bundler and Gemfile to define your dependency on fastlane. This will clearly define the fastlane version to be used and its dependencies, and will also speed up fastlane execution.

  • Install Bundler by running gem install bundler
  • Create a ./Gemfile in the root directory of your project with the content
source "https://rubygems.org"

gem "fastlane"
  • Run bundle update and add both the ./Gemfile and the ./Gemfile.lock to version control
  • Every time you run fastlane, use bundle exec fastlane [lane]
  • On your CI, add bundle install as your first build step
  • To update fastlane, just run bundle update fastlane

Homebrew (macOS)

This way you don't have to install Ruby separately and instead homebrew installs the most adequate Ruby version for fastlane. See this page for details.

brew install fastlane

System Ruby + RubyGems (macOS/Linux/Windows)

This is not recommended for your local environment, but you can still install fastlane to system Ruby's environment. Using sudo often occurs unwanted results later due to file permission and makes managing your environment harder.

sudo gem install fastlane

Setting up fastlane

Navigate to your iOS or Android app and run

fastlane init

fastlane will automatically detect your project, and ask for any missing information.

Questions and support

Before submitting a new GitHub issue, please make sure to search for existing GitHub issues.

If that doesn't help, please submit an issue on GitHub and provide information about your setup, in particular the output of the fastlane env command.

System requirements

fastlane is officially supported to run on macOS.

🐧 Linux and 🖥️ Windows are partially supported. Some underlying software like Xcode are only available on macOS, but many other tools, actions, and the spaceship module can work on other platforms.

Metrics

fastlane tracks a few key metrics to understand how developers are using the tool and to help us know what areas need improvement. No personal/sensitive information is ever collected. Metrics that are collected include:

  • The number of fastlane runs
  • A salted hash of the app identifier or package name, which helps us anonymously identify unique usage of fastlane

You can easily opt-out of metrics collection by adding opt_out_usage at the top of your Fastfile or by setting the environment variable FASTLANE_OPT_OUT_USAGE. Check out the metrics code on GitHub
