Checklist

• I've run bundle exec rspec from the root directory to see all new and existing tests pass
• I've followed the fastlane code style and run bundle exec rubocop -a to ensure the code style is valid
• I see several green ci/circleci builds in the "All checks have passed" section of my PR (connect CircleCI to GitHub if not)

Motivation and Context

Resolves #22115

Description

altool used internally by deliver and pilot has not support Individual API Keys yet.

With this change, fastlane determines the type of API key when uploading a build, and if the API key is a Team API Key, it will use the API key as is, but if it is an Individual API Key, it will not use the key and will use the the application specific password.

Testing Steps

Prerequisites

• Issue your Individual API Key as described in https://developer.apple.com/help/app-store-connect/get-started/app-store-connect-api/
• Issue your application specific password as described in https://support.apple.com/en-us/102654
• Export environment variables in your shell env
  • FASTLANE_APPLE_APPLICATION_SPECIFIC_PASSWORD
  • INDIVIDUAL_API_KEY_ID
  • INDIVIDUAL_API_KEY_CONTENT_BASE64
  • FASTLANE_USER (necessary if it is not specified in your AppFile)
• Build your application with Release configuration

Steps

# fastlane/Fastfile
lane :deploy do
  app_store_connect_api_key(
    key_id: ENV.fetch("INDIVIDUAL_API_KEY_ID"),
    key_content: ENV.fetch("INDIVIDUAL_API_KEY_CONTENT_BASE64"),
    is_key_content_base64: true,
  )
  pilot(ipa: "/path/to/app.ipa")
  deliver(ipa: "/path/to/app.ipa")
end

fastlane deploy

I successfully uploaded my app to TestFlight and AppStore Connect with this branch's fastlane.

If I understand this correctly, when running the pilot command (with distribute_external set), this will:

1. Use altool to upload the build - using app specific password
2. Use the spaceship/testflight command to send for review and distribute to external testers - using individual API key

Did I get it somewhat correctly? :)
