# Xcode will only build the active architecture by default ("My Mac") which results in an
# Apple-silicon-only binary when run on an M-series machine. By explicitly passing both
# architectures and using the generic macOS destination we ensure a universal build.
# The resulting binary is produced at the usual DerivedData location so the rest of the
# script can continue to reference $APP_PATH unchanged.
