Same problem, and the proposed solution does not work

[AmolGangadhare]

@jackdreilly Thanks for the confirmation.

Can you give me some details?

1. Are you trying to run the example in the same plugin?
2. Have you followed all the steps given in README to use it in project?

[AmolGangadhare]

Also, there is a workaround to get it to work.

Open project in XCode -> File -> Workspace settings -> Build system = select legacy build system

Click on done and try to run the app/build with the command.

I will keep you updated on this...

[jackdreilly]

As, well, after making the following change in `flutter_barcode_scanner.podspec` it also worked: ``` s.source_files = 'Classes/**/*.{swift,h,m}' ```

@AmolGangadhare I've tried a clean build and the workaround, the error still remains.

Same problem here, flutter run works, but flutter build ios doesn't.

Edit: doing

s.source_files = 'Classes/**/*.{swift,h,m}'

solved this problem

This issue has been resolved. It will be available in the new release.
