I found this thread, but downgrading Xcode causes other issues, so I would rather not do that. https://forum.unity.com/threads/project-wont-build-using-xode15-release-candidate.1491761/
This is an issue with Unity and Xcode 15, Flutter and this plugin don't really have anything to do with it.
I believe you are more likely to find the solution on the Unity forums or stackoverflow than here,
I had some issues with Xcode 15, but never ran into this one.
Some general tips for Xcode 15 that helped me:
- Make sure cocoapods is updated, versions >= 1.13.0 contains some Xcode 15 fixes.
- Make sure to have a minimum target of iOS 12 on your app and all pods.
- Use a more recent Unity release, for example in the 2021.3.3X or 2022.3.1X range.
- Clean the build folder in Xcode and fully reimport Unity (delete Library folder)
I also experimented with the linker flags mentioned on the Unity forums, but I can't remember if that actually helped.
This can also be an issue with missing flavors. Make sure your Unity Project in XCode has the same BuildConfigurations as your root Runner Project!
