Script to be called as part of an Xcode Run Script build phase. This will ensure that script Input File is copied (and code signed) to script Output File.

#!/bin/sh

# This script embeds (and codesigns) a framework within an iOS app binary, but only when the configuration is Debug.
# It must be called from, or copied into an Xcode Run Script build phase with following setup:
# Input Files:
#     - Path to framework within project folder (source path)
#     - For example: $(SRCROOT)/ThirdPartyFrameworks/SimulatorStatusMagiciOS.framework
# Output Files:
#     - Desired path to framework within ${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH} (destination path)
#     - For example: ${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/SimulatorStatusMagiciOS.framework
#
# For explanation of Input & Output Files, check out: https://indiestack.com/2014/12/speeding-up-custom-script-phases/

not working on XCode 10, needs to be updated (NVM) I ran the wrong target

I tried this too - not working for me on ios app
https://raw.githubusercontent.com/CocoaDebug/CocoaDebug/master/CocoaDebug/copy_and_codesign.sh

maybe try targeting ${CODESIGNING_FOLDER_PATH}
app_frameworks_dir="${CODESIGNING_FOLDER_PATH}/Frameworks"

If it doesn't work for you maybe you need to check your output path.

Check if you need to use CONFIGURATION_BUILD_DIR. For example my "Output Files" was: ${CONFIGURATION_BUILD_DIR}/${FRAMEWORKS_FOLDER_PATH}/MyFancyFramework.framework

How would this work for xcframeworks since those are split under different architectures?
