I’m encountering an issue while trying to build my Flutter app for iOS release. The build fails with the following error:

Error (Xcode): Target release_unpack_ios failed: Exception: Binary /Users/XXX/XXX/XXX/build/ios/Release-iphoneos/Flutter.framework/Flutter does not contain . Running lipo -info:
``


Note: I'm using a translation tool to write this. Any suggestions on how to resolve this? Thank you for your assistance!

I want to resolve this issue and successfully build the app for store submission.


Steps I've taken so far:

- Switched Flutter channels (stable ↔ master)
- Updated Xcode to the latest version
- Upgraded Flutter to the latest version
- Cleaned the project and rebuilt
- Manually copied Flutter.framework to ios/Flutter
- Despite these efforts, the error persists. Any suggestions on how to resolve this?
