This script copies the Reveal library in your .app file on build time as long as you have Reveal installed and you are not building the configuration 'ReleaseAppStore'. For more info please see my blog post: http://ios-coding.com/improved-way-to-integrate-reveal/

lazy-copy-reveal.sh

#!/bin/sh

APPBUNDLEPATH="${TARGET_BUILD_DIR}/${EXECUTABLE_NAME}.app/"

REVEALFRAMEWORKPATH="/Applications/Reveal.app/Contents/SharedSupport/iOS-Libraries/libReveal.dylib"

if [ -f "${REVEALFRAMEWORKPATH}" ] && [ "${CONFIGURATION}" != "ReleaseAppStore" ]; then
	cp "${REVEALFRAMEWORKPATH}" "${APPBUNDLEPATH}"
fi

Shouldn't you put ["${CONFIGURATION}" == "Debug"] instead ?
Because default configuration use Debug and Release
