When XcodeGen silently fails to wire your xcconfig as a baseConfigurationReference, the standard xcconfig → Info.plist flow breaks and $(VARIABLE) resolves to empty. The robust workaround: include the .xcconfig as a regular resource in the app bundle and parse it at runtime with a ~30-line line-based reader. Same file format, same on-disk location — just changes the load mechanism from build-time expansion to runtime read.
