iOS-Legacy.yml

name: CI iOS 6 (armv7)

# The iOS 6 build - RetroArch_iOS6.xcodeproj's defines, ARC, armv7,
# a 6.0 deployment target - compiled against the iOS 9.3 SDK, the last
# that takes a 6.0 floor. No runner Xcode can build armv7 or anything
# below iOS 12 any more, so this runs clang on Linux against the SDK's
# headers, as the PowerPC leg does for old macOS. Every warning is an
# error: anything newer than iOS 6 has to be behind a runtime check,
# and -Wunguarded-availability is what says so.
#
# The checking is .github/workflows/scripts/ios-legacy-check.sh, which
# runs by hand the same way; this job fetches the SDK headers for it.
#
# SDK: theos/sdks, pinned to a commit; only the headers are checked out.
