I am getting a lot of messages of the nature that follows; "RoomPlanExampleApp[606:114689] [ClientDonation] (+[PPSClientDonation sendEventWithIdentifier:payload:]) Invalid inputs: payload={ aneModelPath = "/System/Library/PrivateFrameworks/ObjectUnderstanding.framework/PrecompiledModels/od_af_online.bundle/H14G.bundle/main/main_ane/model.hwx"; bundleIdentfier = "com.example.apple-samplecode.RoomPlanExampleApp9QSS565686"; }" WHAT is the component origin of the message? What can be done to remedy it? This is another example of an error message that does not have enough information for the developer to take remedial action.

Since moving up to IOS18 lat week I am getting an indication that there was a significant drop in IMU data being sent. Using the search capability, I can find very little information in the Developer Documentation that will tell me what the cause is and how to remedy it. Is there some documentation repository like Tech Notes that will tell me what I need to know to get going again? What additional sources of documentation are available for developers? The Search engine used for Developer documentation just does not cut it because it delivered a lot of useless entries that have no obvious relevance to my search terms.

I have some confusion over the definition of MediaType versus DeviceType on the calls. It seems to me that because of similarities between the various cameras and the vague dichotomy between TrueDepth and LiDARData for measuring Depth there may be some need for refinement of the calls. My own preference would be to pass an Attribution Mask based on the bit position of the various characteristics of the device and having the bits prioritized so the BEST selection of the available devices would be chosen. For example With True Depth and LiDAR cameras both have depth data but the LiDAR is preferrable for accuracy reasons but some applications could get by with the photogrammetry mode True Depth camera if the LiDAR camera was unusable for some reason. I could see an option that said "Depth but no LiDAR" being selected. The same thing would be true for telephoto lenses versus combined with Wide or Ultrawide (or Hyper-Wide later). Audio streaming would have the same kind of issues with performance levels for input and output being narrowly defined. The question also arises why Device Type allows an array to be passed but not Media Type. It would seem reasonable for both.

Why are there differences between the Sample application in the download and the code presented in the video? Specifically there are different Imports. I noticed that when I made references to some of the AR functions in. change I made it would not compile clean until I added an import of the ARKit and the Reality Kit even though both are in the RoomPlan import. Does the scope of definitinons get limited to that of the Imported symbols?

In the presentation there was a reference to a Parent/Child relationship. The parent for doors and Windows might be Walls but the relationship between Walls or multiple Windows or doors would be that of a "Sibling" or "Peer" component to maintain logical consistency of the objects. I would also recommend a Junction Object, which means more than an Edge because it would describe the two peer objects that were being joined, and the angle of that junction between the objects. The Junction could also describe the shape of the junction to capture any curvature or discontinuity of the junction. Multiple junctions might also be peers because they would have a junction between other adjoining surfaces giving a more complete description to the structure of the room. The parent of all of these surfaces and junctions would be the Room itself. Such a description would be useful in an architectural review of the room structure.

Where do I start with this error? I am using the Metal Debugger and have.a bunch of stuck command buffers. how do I look at the command buffers to see the errors? My suspicion is that the cause is some sort of memory leak. Not having access to the source for Metal leaves me stuck. The following message shows up in the logging pane of the execution. Execution of the command buffer was aborted due to an error during execution. Ignored (for causing prior/excessive GPU errors) (00000004:kIOGPUCommandBufferCallbackErrorSubmissionsIgnored) Type: Error | Timestamp: 2024-04-11 14:16:13.464336-05:00 | Library: Metal | Subsystem: Metal | Category: Default | TID: 0x2a0b8c I just need some guidance

Where do I get. PerfPowerTelemetryClientRegistrationService which is suddenly missing from my system since upgrading to MacOS15/IOS18?
