Face tracking compatibility with iOS older than iPhoneX

Hi,

Has anyone been able to get the ARFoundation Face tracking to work on older iPhone Devices than the iPhoneX.

Since on Android all ARCore enabled devices can run Face Tracking through AR Foundation, I was wondering if the same would apply to older iOS devices: iPhone 6S, iPhone 7 and iPhone 8.

Thanks in advance.

Yet , Arkit not provide support for older device , but you can use openCV or ARcore using native iOS.
But i hope ArCore provide support for Face tracking in iOS using unity very soon.
