AppIntents Metadata Extraction Fails in Producer Mode with XCRemoteCache

[canhth]

My integration setup

[ x] CocoaPods cocoapods-xcremotecache plugin
[ ] Automatic integration using xcprepare integrate ...
[ ] Manual integration
[ ] Carthage

Expected/desired behavior
After integrating Siri Shortcuts (AppIntents) into my project, I re-enabled XCRemoteCache (producer mode) and started encountering the following error. Everything was working fine a few months ago before Siri Shortcuts was added.

Normal builds (without XCRemoteCache) work as expected, but enabling XCRemoteCache causes this issue.

Expected Behavior

• The build should complete successfully with XCRemoteCache.
• The AppIntents metadata extraction should not halt the build process. Should skip like this:
  note: Metadata extraction skipped. No AppIntents.framework dependency found. (in target 'Broadcast' from project 'MyApp')

Possible Causes / Findings

• XCRemoteCache might not be handling new metadata extraction steps added by Siri Shortcuts / AppIntents.
• This issue happens in producer mode, suggesting something in remote caching logic conflicts with AppIntents processing.
• Apple's documentation suggests that AppIntents may fail on iOS 15 or earlier unless ENABLE_APPINTENTS_DEPLOYMENT_AWARE_PROCESSING=NO is set. Could XCRemoteCache be interfering with this?

Minimal reproduction of the problem with instructions

1. Enable XCRemoteCache in producer mode.
2. Add Siri Shortcuts / AppIntents feature.
3. Attempt a build with XCRemoteCache enabled.
4. Observe the AppIntents metadata extraction error.

Disable remotecache will be normal again.

Hi @polac24 ,
May I ask if you have any idea/suggestion?
