Motivation and Context

This PR improves #21180 which seems to have been abandoned. My team and I have been using the changes from #21180 for a while now. I have synced the branches and fixed failing tests.

Resolves #17639

Description

Deliver
The following app clip default experience functionality has been added to deliver:

• option to specify an action (PLAY, VIEW, ...)
• option to specify localized subtitles
• option to specify localized default experience header image
• option to specify app clip review information

See #21180 for examples

Testing Steps

Basic Testing Setup

1. Update Gemfile to 👇 and run bundle install, bundle update fastlane, or bundle update

gem "fastlane", git: 'https://github.com/sa-ma/fastlane.git', :branch => "pilot-app-clips"

2. Upload a binary to ASC with an app clip target
   • you can follow a project tutorial provided by Apple here

What to Test

Deliver
Before specifying any deliver options:

• Confirm that fastlane uses the live version's app clip metadata for the current edit version
  • It should copy over the action, subtitle, and header image of the live version

After specifying the app clip default experience deliver options:

• Confirm the app clip default experience metadata specified in the deliver options reflects the ASC UI after running deliver
• Confirm that fastlane enforces that the app clip header image is exactly 1800x1200 in size
• Confirm that fastlane enforces only one app clip header image per locale
• Confirm that the additional fastlane messages via UI.{message,important,...} are appropriate

Pilot

• Confirm that the invocations appear on TestFlight
