[angelocarasig]

Is there an existing issue?

• I have searched existing issues

Build info

• ObjectBox version: 4.1.0-beta.2
• OS: iOS18
• Device/chipset: iPhone 16

Steps to reproduce

TODO Tell us exactly how to reproduce the problem.

1. Create a new xcode App
2. Go to File -> Add Package Dependency
3. Paste in https://github.com/objectbox/objectbox-swift-spm and set dependency rule to Next Major Version, set the version to 4.1.0-beta.2
4. Add package and set target to the created xcode project
5. Right click project and run the ObjectBoxGeneratorCommand

Expected behavior

The generator to run with no errors

Actual behavior

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.

[greenrobot-team]

A new preview release of the Swift Package is available: 4.3.0-beta.1

It includes a generator that is compatible with the Xcode 16 project format and "buildable folders".

The latest CocoaPods release (4.3.0) also resolves this issue.

[greenrobot-team]

Update: the latest CocoaPods release "only" supports Xcode 16 projects with either all "buildable folders" or all groups. As the setup.rb script by default adds a generated group, we suggest to convert all folders back to groups until this is fixed.

Note that using the generator through the Swift Package plugin, as in this issue, works as expected.
