How to read current app version in Xcode 11 with script

Question

Until Xcode 11, I used a script that reads the current app version (for the AppStore) and help me change the LaunchScreen since we can\'t use swift for that

Answer 1

How about saving a value to CURRENT_PROJECT_VERSION ? did anyone managed to do this?

I can get the value like

buildNumber=$CURRENT_PROJECT_VERSION

but this doesn't work:

CURRENT_PROJECT_VERSION=""    or   $CURRENT_PROJECT_VERSION=""

In my case I'm trying to set it to ""

This line doesn't set the CURRENT_PROJECT_VERSION field too

/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$appInfoPlist"
