Unable to build opencv 4.6 with contrib for iOS

Is there a opencv 4.6 with contrib readily available for IOS?
I was trying to build opencv with contrib following the official tutorial,
https://docs.opencv.org/4.6.0/d5/da3/tutorial_ios_install.html
but building is failing, also I am not sure if I am building 4.6 or the latest version, I wanted to build 4.6 version open cv with contrib.


python3 opencv/platforms/ios/build_framework.py ios --contrib opencv_contrib --iphoneos_archs arm64 --phonesimulator_archs x86_64
The following args are not recognized and will not be used: ['--phonesimulator_archs', 'x86_64']
Using IPHONEOS_DEPLOYMENT_TARGET=9.0
Using iPhoneOS ARCHS=['arm64']
Using iPhoneSimulator ARCHS=['i386', 'x86_64']
