punktfunk/.gitea/workflows/apple.yml

# Apple client CI — runs on the self-hosted macOS runner (home-mac-mini-1, host mode;
# see scripts/ci/setup-macos-runner.sh). Builds the Rust core into
# PunktfunkCore.xcframework, then builds + tests the Swift package. Network-dependent
# tests (RemoteFirstLightTests) self-skip without PUNKTFUNK_REMOTE_HOST.
#
# A second job (`screenshots`) captures the App Store Connect screenshots of the REAL UI
# (mac window + iOS/iPad/tvOS Simulators, see clients/apple/tools/screenshots.sh) and attaches
# them to the run as a single zip artifact (`punktfunk-appstore-screenshots`). It is isolated
# from the build/test job and best-effort, so a capture gap never reds the core signal.
