Xcode sometimes runs compiled apps translocated (can't find data folder)

forgive this vague bug report, but I'm noticing that sometimes with my students that sometimes when we share projects, the compiled apps are run from Xcode with translocation -- so the app can't find the data folder.

I know the app is translocated because if you print the cwd it's one of those weird auto-generated paths.

I don't have a ton of info available to explain this, but what I've seen is student A gives student B a zip of a project file. Student B compiles it and it's run with translocation from within Xcode. When we use the project generator and/or clean and rebuild the project it doesn't fix things. but student B making a new project, and copying the code and data over to the new project works. So it's perhaps something like a flag that gets set somewhere.

I'm sorry for not having more info on this -- will try to see how I can recreate it, but I've definitely seen it a few times this semester (and was helping debug this last night). It may be something in a new version of Xcode, perhaps it's something like a security flag when running other peoples Xcode projects....

No source files or tests are identified. Start by reproducing the issue with a zipped project opened and run from Xcode, then inspect the working directory and data-folder lookup; done means a shared project reliably finds its data folder when compiled and run from Xcode.
