# Packages the LÖVE2D Pokémon Red port into an iOS app via LÖVE 12.0's
# iOS Xcode project.
#
# Usage: scripts/build_ios.sh [--fetch] [--device] [--release] [--install]
#                             [--version X.Y.Z] [--package-only]
#
#   (default)         Simulator Debug (ad-hoc signed)
#   --device          iphoneos SDK; signing team auto-detected from the
#                     keychain when DEVELOPMENT_TEAM is not set
#   --install         after a --device build, install the app onto the
#                     first connected iPhone/iPad (unlock it first)
#   --release         Release configuration
#   --version X.Y.Z   stamp the engine version into game.love plus
#                     MARKETING_VERSION / CURRENT_PROJECT_VERSION
#   --fetch           Fetch LÖVE 12.0 sources and Apple dependencies into mobile/ios/love-src/
#   --package-only    Zip game.love + apply plist overlay; skip xcodebuild
#
# Prerequisites:
#   - macOS + Xcode (xcodebuild)

# patch still links and still runs, then finds the field nil the moment anyone
# taps Import ROM (#482).  #539 made that degrade to the copy-into-Files flow
# rather than crash, which is the right floor, but a build with no picker at all
# is a silent downgrade, so fail here instead of shipping one.
#
# Checked against the built binary rather than the source, because patching
# love-src proves nothing about what Xcode actually compiled: the shipped
# 0.1.45/0.1.46/0.1.47 IPAs all DO carry the bridge, so the reports that blamed
# a missing patch step were self-built IPAs, exactly the case this catches.
