# Assemble pardes.app from libpardes.a and the Swift sources. Run it through
# `zig build macos-app -Dplatform=macos`, or by hand with the install prefix as
# $1 once `zig build -Dplatform=macos` has produced the library.
#
# There is no Xcode project on purpose. An .app is a directory with a plist and
# a binary in it, swiftc ships with the Command Line Tools, and a hand-written
# pbxproj would be a second build system to keep in step for no gain at this
# stage. What Xcode buys — an xcframework of universal slices, codesigning,
# notarization, a DMG — is distribution machinery; see docs/macos.md for the
# upgrade path when that day comes.

# -lc++ because ghostty-vt pulls in simdutf and highway, which are C++. The Zig
# side bundles compiler_rt/ubsan_rt into the archive (see build.zig), so the
# C++ runtime is the only thing left for this link to supply.
# -target is not optional. Without it swiftc uses the host triple, so
# LC_BUILD_VERSION records whatever macOS built the thing and dyld refuses to
# launch it on anything older — the Info.plist's LSMinimumSystemVersion is a
# claim, not the enforcement. It is also what turns on the availability
# diagnostics that catch a post-13 API before a user does.
