What’s Causing the Error?
The “Undefined symbols for architecture arm64” error typically occurs when there’s a mismatch between the architectures specified in your Flutter project and the ones supported by Xcode 15. This mismatch can be caused by a variety of factors, including:
- Incompatible dependencies or plugins
- Incorrectly configured build settings
- Missing or outdated frameworks
- Clashes between different versions of the same dependency
Step 1: Update Your Flutter Version
To begin troubleshooting, make sure you’re running the latest version of Flutter. Open your terminal and run the following command:
flutter upgradeThis will ensure you have the most recent version of Flutter, which includes fixes for known issues and improved compatibility with Xcode 15.
Step 2: Clean and Rebuild Your Project
Sometimes, a simple clean and rebuild of your project can resolve the error. In your terminal, navigate to your project directory and run the following commands:
flutter clean
flutter pub get
flutter build iosThis will remove any temporary files, retrieve the necessary dependencies, and rebuild your project from scratch.
Step 3: Check Your Build Settings
Xcode 15 introduces some changes to the build settings that can affect your Flutter project. Open your Xcode project and go to the “Build Settings” tab. Ensure that the following settings are configured correctly:
| Setting | Value |
|---|---|
| ARCHS | arm64 armv7 armv7s |
| VALID_ARCHS | arm64 armv7 armv7s |
| ENABLE_BITCODE | No |
Double-check that these settings are correct for both the “Debug” and “Release” configurations.
Step 4: Update Your Pods
Outdated pods can cause compatibility issues with Xcode 15. Open your terminal and navigate to your project directory. Run the following command to update your pods:
pod updateThis will ensure that your pods are up-to-date and compatible with the latest Xcode version.
Step 5: Check for Incompatible Dependencies
Incompatible dependencies can cause the “Undefined symbols for architecture arm64” error. Review your pubspec.yaml file and ensure that all dependencies are compatible with Xcode 15. You can check the compatibility of each dependency by visiting the respective pub.dev page.
For example, if you’re using thecamera plugin, make sure you’re using the latest version that supports Xcode 15:
dependencies:
camera: ^0.8.1+2Step 6: Delete Derived Data and Clean Build Folder
Sometimes, deleting the derived data and cleaning the build folder can resolve the error. In Xcode, go to “File” > “Workspace Settings” and delete the derived data:
Then, clean the build folder by going to “Product” > “Clean Build Folder”.
Step 7: Try a Fresh Install of Flutter
If all else fails, try reinstalling Flutter from scratch. This will remove any corrupted files or configurations that might be causing the error. Run the following command:
flutter uninstall
flutter clean
flutter installThis will remove Flutter, clean up any remaining files, and then reinstall Flutter from scratch.
Conclusion
The “Undefined symbols for architecture arm64” error in Xcode 15 can be frustrating, but by following these steps, you should be able to resolve the issue and get your Flutter app compiling successfully again. Remember to:
- Update your Flutter version
- Clean and rebuild your project
- Check your build settings
- Update your pods
- Check for incompatible dependencies
- Delete derived data and clean the build folder
- Try a fresh install of Flutter
By following this comprehensive guide, you’ll be well on your way to resolving the “Undefined symbols for architecture arm64” error and getting back to building amazing Flutter apps!

Frequently Asked Question
Get the solution to the pesky Flutter compiled error in Xcode 15: Undefined symbols for architecture arm64!
What is causing the “Undefined symbols for architecture arm64” error in Xcode 15?
This error is typically caused by a mismatch between the architectures specified in the Xcode project and the architectures supported by the Flutter framework. In Xcode 15, the default architecture for iOS projects is arm64, but Flutter might not be built for arm64 by default.
How do I fix the “Undefined symbols for architecture arm64” error in Xcode 15?
To fix this error, you can try setting the “Excluded Architectures” to “arm64” in the Xcode project settings, or use the flutter build ios command with the –arch arm64 flag to build the Flutter framework for arm64 architecture.
What are the possible consequences of not fixing the “Undefined symbols for architecture arm64” error?
If you don’t fix this error, your Flutter app might not run on iOS devices with arm64 architecture, which could lead to issues with app performance, compatibility, and even app rejection from the App Store.
Can I use the –no-codesign flag when running the flutter build ios command?
While the –no-codesign flag might seem like a quick fix, it’s not recommended as it can lead to issues with app signing and distribution. Instead, focus on resolving the architecture mismatch to ensure a smooth and secure app development process.
Where can I find more resources to troubleshoot Flutter compiled errors in Xcode 15?
For more resources and troubleshooting tips, you can check out the official Flutter documentation, the Flutter GitHub issues page, or online communities like Stack Overflow or Reddit’s r/FlutterDev.
