# This script is a bit of a hack to generate DocC documentation until Bazel has support for it.
# https://github.com/bazelbuild/rules_apple/issues/2241
# To use this script, make sure the XCFramework is built with Bazel (see ios-ci.yml).
# Then to start a local preview, run:
# $ scripts/docc.sh bazel
# You can also build the documentation locally
# $ scripts/docc.sh
# Then go to build/ios and run
# $ python3 -m http.server
# Go to http://localhost:8000/documentation/maplibre/
