Fixing the AMSupportURLConnectionDelegate Class Conflict in Flutter on M1 Macs

If you're a Flutter developer using an Apple M1 chip, you might have encountered a frustrating issue during your iOS app build process. The error message, "Class AMSupportURLConnectionDelegate is implemented in both ?? (0x1eb0e27a0) and ?? (0x1162f02b8). One of the two will be used. Which one is undefined," can leave you perplexed and your project stalled. But fear not! In this guide, we will dive into this issue and provide a simple, step-by-step solution to get you back on track.

Understanding the Problem

When running a Flutter application on an M1 Mac, you might run into build errors that originate from class name conflicts. Specifically, the AMSupportURLConnectionDelegate and AMSupportURLSession are causing your app's build to fail. The conflict happens because the same classes are implemented in different places within your project, and the build system does not know which one to use.

Key Error Messages

Class AMSupportURLConnectionDelegate is implemented in both...

Class AMSupportURLSession is implemented in both...

BUILD FAILED

This type of error can often mislead developers into thinking there’s a significant issue within their app's code when the root cause may lie elsewhere.

Step-by-Step Solution

Here's how you can resolve the issue effectively and get your application built successfully:

Step 1: Navigate to Your Flutter Project

Open Finder and go to the root directory of your Flutter project where your code resides.

Step 2: Open the Xcode Project

Inside your Flutter project folder, locate and open the YourAppName.xcodeproj file. This is typically found under the 'ios' folder.

Step 3: Open the Workspace File

Within Xcode, navigate to and open the Contents.xcworkspace file. This step is crucial because it ensures that all dependencies are properly linked when you run your project.

Step 4: Build and Run the Project

Press the play button (Run) in Xcode to build your application. Don’t worry if the build fails at this stage—this is expected.

Step 5: Check the Error Logs

After the build fails, carefully check the Xcode error logs. Tellingly, the AMSupportURLConnectionDelegate warning is not the root cause of your build failure. Look for other relevant error messages within the logs that can direct you to the actual problem.

Conclusion

Building Flutter applications on M1 Macs can sometimes introduce specific technical hurdles, especially when it comes to class implementations within Xcode. By following the steps listed above, you can quickly identify and troubleshoot the underlying issue without being misled by secondary error messages.

Additional Tips

Always ensure you are running the latest versions of Flutter and Xcode, as updates often include important fixes for compatibility issues.

If you're using third-party packages, check their compatibility with the M1 architecture.

Armed with this information, you should now have the tools to overcome the AMSupportURLConnectionDelegate class conflict in your Flutter project on M1 Macs. Happy coding!
