🐛 [mediapipe_genai] Unable to Submit IOS App - arm64_libllm_inference_engine.framework does not support the minimum OS Version specified

[aaronrau]

Bug report

Describe the bug
Unable to distribute the example app to Testflight for internal testing. Error:
Runner.app/Frameworks/arm64_libllm_inference_engine.framework does not support the minimum OS Version specified in the Info.plist.

Steps to reproduce

in the EXAMPLE/IOS https://github.com/google/flutter-mediapipe/tree/main/packages/mediapipe-task-genai/example

1. run flutter build ipa
2. Drag and drop the "build/ios/ipa/*.ipa" bundle into the Apple Transporter macOS app https://apps.apple.com/us/app/transporter/id1450874784
3. Click on the distribute button
4. Apple returns the error

Asset validation failed (90208)
Invalid Bundle. The bundle Runner.app/Frameworks/arm64_libllm_inference_engine.framework does not support the minimum OS Version specified in the Info.plist. (ID: 9e7cf909-70a6-4ccb-840e-ee10cbe8da8c)

Expected behavior

Able to distribute the example app to testflight

Additional context

Able to run the build in debug on iPhone 15 device. Just can't distribute the build.

vtool -show Products/Applications/Frameworks/arm64_libllm_inference_engine.framework/arm64_libllm_inference_engine

The minimum version in arm64 is IOS 16.1 
Load command 10

But the flutter package Frameworks/arm64_libllm_inference_engine.framework/Info.plist appears to be 12.0 this is causing a conflict

[aaronrau]

Manually editing the Frameworks/arm64_libllm_inference_engine.framework/Info.plist seems to fix the problem

From

<key>MinimumOSVersion</key>
<string>12.0</string>

To

<key>MinimumOSVersion</key>
<string>16.1</string>

[craiglabenz]

Thanks for your investigations here, @aaronrau. Are you able to open a PR with that change to the example app's Info.plist file? Admittedly, I didn't think about distributing the example app - but it would probably be a fun thing to play with on your phone :)

[aaronrau]

@craiglabenz I'm not familiar with how the native assets are being built and linked. I think it's something related to https://github.com/google-ai-edge/mediapipe/blob/f936711aca489b30f75fde4535e60b8030e127a1/mediapipe/tasks/ios/genai/core/BUILD gets build. I think it's with that process?
Attached is the screenshot inside the app bundle where it needs to be changed.
