++ # Drop-in xcodebuild replacement with retry logic for QTBUG-138855.
++ #
++ # The test_i18n_subdir*_xcode tests occasionally fail due to a spurious
++ # xcodebuild crash during CMake's compiler detection phase. This appears
++ # to be an issue with the Xcode/Parallels VM combination on CI machines,
++ # manifesting as "thread is already initializing this class!" errors.
++ #
++ # This script is used as the MAKE_PROGRAM for Xcode generator tests.
++ # It runs xcodebuild with retry logic, detecting the spurious failure
++ # pattern and retrying up to 3 times if detected.
++ #
++ # POSIX-compliant shell script for compatibility with macOS /bin/sh.
