TODO Tell us exactly how to reproduce the problem.

1. Create a new xcode App
2. Go to File -> Add Package Dependency

Expected behavior

The generator to run with no errors

A crash.

Logs, stack traces

Running the setup.rb file similarly with the cocoapods approach nets me an error log like below with a more detailed idea on whats happening but unsure how to fix it

Thanks for reporting! This is a known issue when using an Xcode 16 project that uses buildable folders instead of groups (in the Xcode 16 release notes search for "Buildable folders").

For our reference, this is internal issue objectbox-swift#308

[greenrobot-team]

This will be fixed with an upcoming version as it requires major changes to the ObjectBox generator.

Until then, we recommend to stick to the Xcode 15.3 project format.

If you already have created or upgraded to an Xcode 16 project, you can change the format in the Project Navigator pane (on the right) after clicking on the project. Also make sure to convert any folders to groups.
