Flutter App Build Fails on M2 MacBook Air with Rosetta Error: "Attachment of code signature supplement failed"

Question

I am encountering an issue when building ipa file of my Flutter App on my M2 chip MacBook Air. The app build successfully on my Mac Studio, but always fail on the laptop with the error:

error: rosetta error: Attachment of code signature supplement failed: 1
/var/db/oah/696e0658733369639e73a08cf7f6dc139beb7664301bce347578c8abc0ea947d/5736a6a6d3f8f7c6d96e251fef39431e4470b986151c860a80189c719e1eaf9d/gen_snapshot_arm64.aot
Dart snapshot generator failed with exit code -6
Target aot_assembly_release failed: Exception: AOT snapshotter exited with code -6

Command I use to build ipa

flutter build ipa

I tried the following suggested answers from the other posts.

Clean rebuild

flutter clean
rm -rf ios/Pods
rm -rf ios/.symlinks
rm -rf ios/Flutter/Flutter.framework
rm -rf ios/Flutter/Flutter.podspec
flutter pub get
cd ios
pod install
flutter build ipa

Re-install rosetta

softwareupdate --install-rosetta

Flutter doctor -v

Flutter Create a new project

copy-and-paste old code files to new folder
flutter pub get
cd ios
pod install

But none of them seem working. I have the exact same error when I tried to archive using XCode toolbar "Product->Archive". If anyone has any insight to how to resolve this rosetta error it would be very much appreciated.

Solution

I upgraded the OS two weeks ago (Sequoia 15.0 to 15.1), but it still failed to build the IPA file. I initially thought that upgrading the OS wouldn't help.

Today, I checked for updates to both the OS and Xcode. There was an available update (OS 15.2 and Xcode 16.2). After upgrading the OS and Xcode, and then rebooting, the error message disappeared.

Advice

Always ensure that your OS and Xcode are up to date.
