-## Special note about debugging
+## Special notes about debugging xcode projects
+Note that when generating Xcode projects, it is necessary to supply the `--@build_bazel_rules_ios//rules:local_debug_options_enabled` so that debugging of swift files will work.
+
 Debugging does not work in sandbox mode, due to issue #108. The workaround for now is to disable sandboxing in the .bazelrc file.
