How to automatically set the version and build number of a Watchkit app target

Question

The version and build number (or version and short version) of a Watchkit app and extension have to be set to the same value as the containing app.

I use environment variables to set the apps version in the Info.plist dynamically at build time. That also works fine for the Watchkit extension, but not for the Watchkit app.

The environment variables I use have to be provided in the plist for the main app and extension without ${} (for variable ${VERSION} I set VERSION).
if I do the same for the Watchkit app, it is taking the string itself, not the value. If I provide it with dollar & brackets there is no data in the variable.

Any idea how to set the variables for the Watchkit app?

I use this to update all the targets:

#!/bin/bash buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE") buildNumber=$(($buildNumber + 1)) /usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE" /usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$SRCROOT/Great WatchKit App/Info.plist"
