Please define inputPaths and outputPaths, so that this phase doesn't have to run every time in incremental builds.

I don't understand why we need to copy source files into BUILT_PRODUCTS_DIR, or why this cannot be done with a copy files phase.

The issue here is the same as the one below:

Project files are subject to the following limitation: their locations must not be variable, outside of the standard enumerated list of variable file locations: BUILT_PRODUCTS_DIR, SDK_DIR, PROJECT_DIR, etc. The issue with these files in particular is that they are either in BUILT_PRODUCTS_DIR or SDK_DIR depending on configuration and internal SDK status.  Hence both not being able to put those files directly in the project in their original location. This solution intends to work around that problem by collapsing the two possible locations of these files (SDK_DIR and BUILT_PRODUCTS_DIR) into one by copying the files in SDK_DIR into the BUILT_PRODUCTS_DIR only if they are newer.

A Copy Files build step would not be appropriate here, because these files should only be copied in particular configurations, and that's not something Copy Files can do.

I can try to define input and output files  (the output side is easier), but input files may need to be in the project, which would lead to duplicate filenames inside the project. But I'll see what I can do.

Oh, and we can't just put both files in the project, because the technique of using EXCLUDED_SOURCE_FILE_NAMES depends on having uniquely named source files (not unique paths), and these would have the same names.

On the other hand, the inputPaths and outputPaths just take arbitrary strings with fully generated build variable support, so I've added these to the Copy step, and verified that the script does not run if the files haven't changed.
