# 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.
