# Refresh CocoaPods trunk/CDN specs and install iOS pods with --repo-update.
#
# Cordova runs plain `pod install` during `platform add` / plugin install / build.
# Without a prior spec refresh, a stale ~/.cocoapods cache (common in CI) can miss
# newly published pod versions (e.g. AppsFlyerFramework 6.18.1).
#
# Usage:
#   ./scripts/cordova-ios-pod-install.sh --update-specs
#     Refresh CDN/trunk specs only (no Cordova project required). Call this
#     before `cordova platform add ios` so plugin pod install can resolve.
#
#   ./scripts/cordova-ios-pod-install.sh [cordova_project_dir]
#     --update-specs, then cordova prepare ios + pod install --repo-update when
#     platforms/ios exists.
#
# Env:
#   CORDOVA_IOS_POD_REPO_UPDATE  1 = run (default in GitHub Actions), 0 = skip
