# iOS Simulator E2E Sync Test Setup
#
# Usage: ./scripts/ios-sync-test.sh
#
# This script:
# 1. Starts a local server with fresh temp data
# 2. Creates a server profile (gets UUID for folder-based routing)
# 3. Seeds test items on the server
# 4. Finds the iOS simulator app container
# 5. Pre-configures profiles.json with server URL, API key, server_profile_id
# 6. Clears last_sync timestamps for a fresh pull
# 7. Opens Xcode (build & run from there)
#
# The server keeps running until you press Ctrl+C.
