# Roomfit Studio (B2B) — iOS Fastlane
#
# This lane file is the ONLY supported way to produce a release archive.
# Manual `flutter build ipa` / Xcode Archive runs have repeatedly shipped
# builds without `--dart-define=SUPABASE_ANON_KEY`, which Apple rejected
# under Guideline 2.1(a) on 2026-04-21. Every lane below validates the
# environment before invoking Flutter, so a misconfigured build cannot
# reach App Store Connect.
