[cmake-developers] [PATCH 2/9] Xcode: Sort Xcode objects by Id

[Tim Blechmann]

>>> Effectively it is a UUID for our purposes.  The ordering Gregor
>>> proposes is to match what Xcode writes when it generates the .pbxproj
>>> file, and we can't choose that.

>> i see ... is it (easily) possible to lexicographically sort he

> If Xcode can save and load projects with user-specified ordering then
> CMake may be able to generate things accordingly.  Try creating a project
> with the IDE, saving it, copying it, and then updating the order in the
> IDE and saving again.  Compare the saved project files.  Where is the
> order stored?
