Fastlane Build

Fastlane streamlines iOS app building and deployment. This recipe shows how to set up a complete build pipeline with gem installation, CocoaPods dependency resolution, and Fastlane execution.

Complete YAML

name: iOS Build
platform: ios
environment:
  xcode: "16.4"

triggers:
  - push
  - pull_request

steps:
  - name: Install gems
    run: bundle install

  - name: Install pods
    run: pod install

  - name: Build app
    run: fastlane build

Key Points

Gem Installation: bundle install installs all Ruby gems specified in your Gemfile, including Fastlane and other build tools
Pod Installation: pod install resolves and downloads your CocoaPods dependencies
Fastlane: The fastlane build command runs your build lane defined in your fastlane/Fastfile

Typical Fastfile Structure

Your fastlane/Fastfile might look like:

default_platform(:ios)

platform :ios do
  desc "Build the app"
  lane :build do
    build_app(
      workspace: "MyApp.xcworkspace",
      scheme: "MyApp",
      configuration: "Release",
      derived_data_path: "build/DerivedData",
      destination: "generic/platform=iOS",
      skip_package: true
    )
  end
end
