# Build Ghostty's ORIGINAL Swift macOS app (unchanged) against the Rust core.
#
# Ghostty's Xcode project (<ghostty>/macos/Ghostty.xcodeproj) links
# `macos/GhosttyKit.xcframework` and bundles resources from `../zig-out/share`
# (see the Zig build's src/build/GhosttyXcodebuild.zig). The Rust libghostty
# exports the identical include/ghostty.h ABI, so this script produces both
# from the Rust workspace and then runs xcodebuild, exactly like
# `zig build -Demit-macos-app`:
#   1. scripts/xcframework.sh  -> <ghostty>/macos/GhosttyKit.xcframework
#   2. `just install`          -> <ghostty>/zig-out/share/{ghostty,terminfo,...}
#   3. xcodebuild -target Ghostty -configuration <CONFIG> (clean env, like Zig)
#
# Usage: scripts/macos-swift-app.sh <path-to-ghostty-source> [Release|Debug|ReleaseLocal]
# Runs only on macOS (Xcode required). DRY_RUN=1 prints the commands instead.
