# Downloads BeeWare's Python-Apple-support builds and assembles a universal
# Python.xcframework (macOS + iOS device + iOS simulator) under Frameworks/.
#
# `xcodebuild -create-xcframework` only keeps each slice's Python.framework. On
# macOS that's enough — the stdlib lives inside the framework. On iOS the stdlib
# ships *next to* the framework, so it gets dropped; we restore it afterwards,
# along with BeeWare's build/ helper scripts that the consuming app runs to stage
# and code-sign the stdlib into its bundle (see README "iOS integration").
