Script for copying header files in an Xcode library/framework project while retaining their hierarchical structure. This requires creating a headers-bom file listing relative paths to the headers to be copied. Using rsync makes things relatively painless and potentially even more efficient than other methods.

copy-headers.sh

#!/bin/sh

echo PWD = ${PWD}
echo SRCROOT = ${SRCROOT}
echo BUILT_PRODUCTS_DIR = ${BUILT_PRODUCTS_DIR}

  # just to be sure
cd ${SRCROOT}

  # using . as source below might not be what you want... feel free to change, etc.
rsync -rtlRv --files-from=header-bom.txt . ${BUILT_PRODUCTS_DIR}/include/
