Fastfile Patterns

Beta to TestFlight

Fastfile

default_platform(:ios)

platform :ios do desc "Push a new beta build to TestFlight" lane :beta do increment_build_number(xcodeproj: "App.xcodeproj") build_app(scheme: "App") upload_to_testflight( skip_waiting_for_build_processing: true ) end end

App Store Release

lane :release do capture_screenshots build_app(scheme: "App") upload_to_app_store( submit_for_review: true, automatic_release: true, force: true, skip_metadata: false, skip_screenshots: false ) end

Testing Lane

lane :test do run_tests( scheme: "AppTests", devices: ["iPhone 15 Pro"], code_coverage: true ) end

App Store Connect API

Appfile

app_identifier "com.example.app" apple_id "developer@example.com" team_id "ABC123"

API key auth (recommended)

Store key file securely

lane_context[SharedValues::APP_STORE_CONNECT_API_KEY] = app_store_connect_api_key( key_id: "ABC123", issuer_id: "def-456", key_filepath: "./AuthKey.p8" )

Code Signing

Match (Recommended)

lane :sync_certs do match( type: "appstore", app_identifier: "com.example.app", git_url: "git@github.com:org/certs.git" ) end

lane :beta do match(type: "appstore") build_app(scheme: "App") upload_to_testflight end
