Is AR Foundation 4.2.7 compatible with iOS 16.2? (and URP 12.1.8)?

Hi Unity Team

I’m getting drift and rotation issues on both Android, as well as iOS 16.2 on iPad Pro M2 with AR Foundation 5.0.3.

It sounds similar to the issues described here:

So I’m wondering if downgrading to 4.2.7 will make things better until the issue is solved in AR Foundation 5.x

I just dont know if 4.2.7 will work with iOS 16.2. Would hate to redo entire project by downgrading, then finding out iOS 16.2 is not supported. I’m also using URP 12.1.8

AR Foundation 4.2.7 is compatible with iOS 16.2, but downgrading Unity’s AR packages will have no affect on tracking quality in iOS. Both versions of Unity’s ARKit provider use the same ARKit API in the iOS version installed on your device.

On Android, downgrading ARFoundation and ARCore packages from 5.0.3 to 4.2.7 corresponds to an ARCore downgrade from 1.31 to 1.24 (Changelog | Google ARCore XR Plugin | 5.0.7). This could possibly affect tracking quality but Google has not documented anything to that effect.

There was some camera input drift occuring in AR Foundation 5.X when using Input System’s TrackedPoseDriver. This is fixed starting from the following Unity versions:

  • 2021.3.29f1
  • 2022.3.6f1
  • 2023.1.5f1
  • 2023.2.0a23

This should greatly improve stability for tracked objects.
