Strip Intel architecture's from Xcode frameworks for use on Apple Silicon

strip-intel.sh

#!/bin/sh

# strip-intel.sh
# Usage example: ./strip-intel.sh

# This script is design to remove Intel architecture's from Xcode frameworks 
# to enable development and installation of 3rd party pre-compiled frameworks
# that are not currently distributed as either XCFramework or SPM packages.

# The most common use-case would be carthage dependencies that are distributed
# as pre-compiled Universal framework.
