Here’s a memo on how to execute Run Script only during Release builds in iOS app development.

As shown below, you can write it so that the if statement branch is executed only when the CONFIGURATION value is Release.

if [ "${CONFIGURATION}" = "Release" ]; then
  echo Do something really release-like
fi
