Value of type 'UnityAppController' has no member 'unityMessageHandler'

Describe the bug
Latest Bitcode fix has broken iOS builds

UnityPlayerUtils.swift line 96
Value of type 'UnityAppController' has no member 'unityMessageHandler'

I can see this is related to the latest change to enable building with bitcode enabled.

Was due to not updating the UnityFlutterIntegration.package

Excuse me, I have the same error, what do you mean by not updating the UnityFlutterIntegration.package?
Do you mean the flutter_unity_widget package on flutter?

Thanks

Any solutions? :(

This file needs to be updated for 4.1

Sometimes these extra lines that the build process is meant to add in fails to generate.

There should be two entries in UnityAppController.h and UnityAppController.m

I think if you look back at your git history you may be able to restore these files. Alternatively I've just had to keep runnning the build until they actually generate.

To get this to work, I had to remove the Unity-iPhone.xcodeproj from within my project (Move to Trash), then regenerate the Unity project entirely. Be sure to also clean your build folder(s) to ensure that there are no leftover files that could interfere with any of the fresh build process.
