Xcode 26: Type does not conform to protocol '__EntityRelatable' via SPM + ObjectBoxGeneratorCommand

[Mathimatica]

Is there an existing issue?

• I have searched existing issues

Build info

• ObjectBox version: 5.0.0
• OS: iOS 26, building with Xcode 26
• Device/chipset: iPhone 16

Steps to reproduce

1. Add ObjectBox via SPM and use 5.0.0 ( latest as of this ticket creation )
2. Add in the sample Person example from https://swift.objectbox.io/getting-started
3. Run Code Generator Plugin by right clicking project and choosing ObjectBoxGeneratorCommand
4. Add Generated file to project and add it to app target
5. Try to compile app

Expected behavior

the project should compile with no issue

Actual behavior

project fails to compile and gives : Type 'Person' does not conform to protocol '__EntityRelatable'

Does the generated file (.generated.swift file extension) contain an extension that implements ObjectBox.__EntityRelatable for Person? Like for the example project in this repo?

Could you share your example project?

I quickly tried this with a new iOS Xcode project following our instructions and everything works as expected.

Absolutely, here is a Sample Project I just put together:

https://github.com/Mathimatica/TestObjectBox#

Build with Xcode Version 26.0.1 (17A400)
Minimum iOS SDK 26.0
On an M4 Mac

@Mathimatica Thanks! However, when I build "TestObjectBox" for "Any iOS Simulator Device" through Product > Build the build succeeds.

What exactly are you trying to do?

[Mathimatica]

thats very weird, when I do it I get:

having said that, what I did was is I downloaded your guys Notes sample and rebuild my app around your project and it builds fine, so I really have no idea what would cause it

Maybe have a look at the full build output (in Report Navigator under Build, make sure to show "All Messages") if there is any helpful message there?

Does it work when building for a simulator instead of an iOS device?
