# Orca Mobile iOS release lane.
#
# Builds the prebuilt iOS workspace, signs it with the distribution identity
# imported into the CI keychain plus an explicit App Store provisioning profile
# fetched via the App Store Connect API key, then uploads the .ipa to
# TestFlight. All Apple credentials come from CI env vars
# (see .github/workflows/mobile-ios-release.yml) so nothing secret lives in the
# repo.
#
# Why manual signing (not -allowProvisioningUpdates / automatic cloud signing):
# mixing a pre-imported distribution .p12 with xcodebuild's cloud-managed
# automatic signing produced "Cloud signing permission error / No profiles
# found" at exportArchive (cloud signing also needs an Admin-role API key).
# Instead we fetch an explicit profile with the API key (sigh) and sign
# manually against the imported cert — works with any team API key.
