+#
+# macOS LaunchServices registers EVERY QuickDrop.app on disk that shares the bundle id
+# (com.leonboettger.neardrop) -- Debug build, Release build, archives, old DerivedData, ... -- and the
+# share sheet then picks among those duplicates heuristically, so a stale copy can run instead of the
+# one you just built. This script makes the freshly built app the ONLY registered copy of that bundle id.
+#
+# Usage:
+#   - Standalone:  scripts/use-dev-share-extension.sh        (re-points Finder at the newest Debug build)
+#   - Xcode:       add as a Run post-action (Product > Scheme > Edit Scheme > Run > Post-actions >
+#                  "+" > New Run Script Action; "Provide build settings from: QuickDrop"; paste:
+#                      "${SRCROOT}/scripts/use-dev-share-extension.sh"
+#                  Post-actions run outside the build sandbox, so lsregister/mdfind work there even
+#                  though ENABLE_USER_SCRIPT_SANDBOXING is YES for build phases.
