I developed a XCode project using Flutter (v. 3.35.6). The application basically has a IntentExtension to handle intents donation and the related business logic. We decided to go with ShortcutExtension in place of AppIntents because it fits with our app's use case (where basically we need to dynamically donate/remove intents).

We have an issue building the project, and it is due to the presence of the IntentExtension .appex file in the Build Phases --> Embed Foundation Extensions. If we remove it , the project builds however the IntentHandling is not invoked in the Shortcuts app.

Build issue:

Generated error in the console: Cycle inside Runner; building could produce unreliable results.

Focus on these details of a cycle in your build graph, lightly formatted here for clarity:

Cycle inside Runner; building could produce unreliable results. Cycle details: → Target 'Runner' has copy command from '<snip>/DerivedData/Runner/Build/Products/Release-quality-iphoneos/ShortcutsExtension.appex' to '<snip>/DerivedData/Runner/Build/Products/Release-quality-iphoneos/Runner.app/PlugIns/ShortcutsExtension.appex'
     ○ That command depends on command in Target 'Runner': script phase “[CP] Copy Pods Resources”
     ○ That command depends on command in Target 'Runner': script phase “[CP] Embed Pods Frameworks”
     ○ That command depends on command in Target 'Runner': script phase “FlutterFire: "flutterfire upload-crashlytics-symbols"”
     ○ That command depends on command in Target 'Runner': script phase “FlutterFire: "flutterfire bundle-service-file"”
     ○ That command depends on command in Target 'Runner': script phase “Thin Binary”
○ Target 'Runner' has process command with output '<snip>/DerivedData/Runner/Build/Products/Release-quality-iphoneos/Runner.app/Info.plist'
○ Target 'Runner' has copy command from '<snip>/DerivedData/Runner/Build/Products/Release-quality-iphoneos/ShortcutsExtension.appex' to '<snip>/DerivedData/Runner/Build/Products/Release-quality-iphoneos/Runner.app/PlugIns/ShortcutsExtension.appex'

You'll have to reason about what build step truly needs to depend on something else, and where there's no real dependency so that you can break apart the cycle — the documentation has information on how to think about this error.

You'll probably want to break the dependency graph here somewhere in the steps that I intended in this error. but I can't say that definitively because those build phases all come from third-party tooling that isn't part of Xcode. As such, you should contact the support provided by those tools to understand the configurations required by each of those tools in their respective build steps.
