# release.sh — archive Workouts (iOS app with the embedded watch app) and upload
# to TestFlight / App Store Connect. No third-party tooling: pure xcodebuild + the
# App Store Connect API key. Credentials live in .env.release (gitignored); see
# .env.release.example.
#
# What it does:
#   1. Regenerates the Xcode project with XcodeGen.
#   2. Stamps CFBundleVersion (CURRENT_PROJECT_VERSION) with the git commit count
#      for both the iOS app and the embedded watch app.
#   3. xcodebuild archive  (the watch app rides along in the same archive)
#   4. xcodebuild -exportArchive with destination=upload -> App Store Connect.
