I have an existing ARKit motion capture app that I recompiled in the new Xcode beta and ran on an iPad Pro (LiDAR model) running iOS 15 beta. I ran it alongside my iPhone 12 Pro running iOS 14.6 and did a video recording of both to see the improvements to motion capture. The recordings are identical which suggests to me that the ARKit 5 improvements were not enabled somehow. Is there something more I need to do? Does the current iOS 15 beta include the ARKit 5 changes?
