A few users have recently reported no longer being able to capture point clouds using our app, specifically on iPhone 15 Pro devices. We recently found an in-house device that exhibits this behavior and found that the confidenceMap contains only low confidence values, regardless of the environment being captured. Our app uses a higher confidence threshold; setting the threshold to a lower value produces noisy results as expected, so that is a non-viable option. Other LiDAR based apps have been tested with this device and the results are the same. No points, or noisy point clouds in apps that allow a lower confidence threshold setting. On devices that exhibit this behavior the "Displaying a point cloud using scene depth" Apple sample app can be used to visualize the issue. First reports of this new behavior occurred as early as iOS 18.4. Looking for recommendations on which team(s) at Apple to reach out to with these findings since the behavior manifests on only a small sample of devices.

Seeing a flurry of these in Xcode 15 Beta 8 while debugging an ARKit app <<<< AVPointCloudData >>>> Fig assert: "_dataBuffer" at bail (AVPointCloudData.m:217) - (err=0)

M1 iPad Pro with iPadOS 16 Beta 3 Xcode 14.0 beta 3 In a freshly created Xcode 14 beta 2 app using the Augmented Reality App template with Content Technology set to Metal, ARWorldTrackingConfiguration.recommendedVideoFormatForHighResolutionFrameCapturing returns a 60 fps, 1920 x 1440 video format. So, session.captureHighResolutionFrame fails to deliver a high res frame.

In the function processLastArData() a command buffer is committed and the output of the last MPS is immediately assigned without issuing a waitUntilCompleted() on the buffer.
