A sample of some error messages that are presented in the Xcode log for executon of a program. There is nothing in the messages that will help identify a component as the origin of the message, nor is there a locatable derinition for the various labels and fields of the text. What component or even framework does this set of messages originate? Your search engine is useless because it returns gibberish. It doesn’t even follow the common behavior of SEARCH ENGINES because it takes label strings compounded from common words and searches for the common word instead of using the catenated string that is the internal variable name that is in the text. 2024-06-22 19:45:58.089943-0500 RoomPlanExampleApp[733:30145] [ClientDonation] (+[PPSClientDonation isRegisteredSubsystem:category:]) Permission denied: GenerativeFunctionMetrics / ANEInferenceOperationPrepareForEncode.

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. "2024-06-20 19:27:00.669334-0500 RoomPlanExampleApp[902:299709] [Technique] ARWorldTrackingTechnique <0x104bf6d80>: SLAM error callback: Error Domain=Slam Error Code=7 "Non fatal error occurred due to significant drop in a IMU data" UserInfo={NSDescription=Non fatal error occurred due to significant drop in a IMU data, NSLocalizedFailureReason=SlamEngineNodeGroup Failure: IMU issue: gyro data stream verification failed [Significant data drop].

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.

This is one of the files being looked for during initialization of the RoomPlan WWDC Demo package but it cannot be found since moving to IOS 18.0. it is not anyrhere since the upgrade.

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

Why do I get this error almost immediately on starting my rendering pass?

with the latest Xcode that runs with Mac OS 14.5 Developer Beta has messages with a time and date in them There are also some other fields of an indeterminate origin/type. "2024-05-06 15:37:32.383996-0500 RoomPlanExampleApp[24190:1708576] [CAMetalLayerDrawable texture] should not be called after already presenting this drawable. Get a nextDrawable instead." specifically I need to know how the string [24190:1708576] relates to a location in my application so I can act on the message. I certainly can't find the text in the "[CAMetalLayerDrawable texture]". field anywhere in the user documentation OR the Development documentation. In order for a diagnostic message to be Actionable and remedied by a user it must identify the module and source line of the initiating code and there must be accessible documentation for users to access to get an explanation of potential remedies.. This interface fails to supply enough information to diagnose the problem. The label in [CAMetalLayerDrawable texture] cannot even be found in a search of the package information attached to the Xcode Release paired with the IOS and Mac OS system releases.

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

It appears that when a class like the following: " class RoomCaptureViewController: UIViewController, RoomCaptureViewDelegate,ARSCNViewDelegate, MTKViewDelegate, ARSessionDelegate, RoomCaptureSessionDelegate. " has multiple delegates, the ordering of the priority of each message is delivered to a delegate by a priority sensitive order based algorithm and that one message can be processed by only one delegate and not passed off to other delegates if they don't have the proper entry points. Specifically I noted that changing the order seems to result in a delegate not getting a message that it should be seeing. Is there a "handoff" call that can be made after a delegate has seen a message but needs to pass it off to another delegate for processing? This is a protocol typically utilized in Interrupt handlers for PCIe and other messaging protocols and I have not been able to find a similar capability In the voluminous documentation available for IOS and Mac systems. I would also like to know how a message is dispatched by a class to the particular delegate for which the message was intended. Is there a detailed document that explains how the messaging protocol works that is not so fragmented as to require having multiple monitors open in order to form a coherent picture of the messaging interface for Delegates belonging to a class?

When running a modified version of the RoomPlan Demo I get frequent Session Interrupted conditions. In looking at the traces I find a status of SensorDidPause in the interruption Side of the error but am mystified as to how to determine which sensor it was that paused and how to diagnose it. It appears there is a bitmap of available and active sensor devices in the sensor info passed with the session data on the error. In looking at the error status I can see that one or two of the motion sensors have had a problem. How do I do further diagnostic checks on what the cause of the error is? I am also curious why the error occurred as soon as the AR Session for my test started via the “session.run” call. The documentation in this area seems difficult to find. Attached are traces from running the test and stack dumps for the calls. Please send me guidance on how to proceed. The device in question is an iPad iPhone(3) that is attached to the Mac mini named “Hawkeye”. There is no known direct involvement for the Hawkeye system

I am running a modified RoomPllan app in my test environment I get two ARSessions active, sometimes more. It appears that the first one is created by Scene Kit because it is related go ARSCNView. Who controls that and what gets processed through it? I noticed that I get a lot of Session Interruptions from Sensor Failure when I am doing World Tracking and the first one happens almost immediately. When I get the room capture delegates fired up I start getting images to the delegate via a second session that is collecting images. How do I tell which session is the scene kit session and which one is the RoomCapture session on thee fly when it comes through the delegate? Is there a difference in the object desciptor that I can use as a differentiator? Relying on the Address of the ARSession buffer being different is okay if you get your timing right. It wasn't clear from any of the documentation that there would be TWO or more AR Sessions delivering data through the delegates. The books on the use of ARKIT are not much help in determining the partition of responsibilities between the origins. The buffer arrivals at the functions supported by the delegates do not have a clear delineation of what function is delivered through which delegate discernible from the highly fragmented documentation provided by the Developer document library. Can someone give me some guidance here? Are there sources for CLEAR documentation of what is delivered via which delegate for the various interfaces?

Do I need an entitlement to use the ARWorldTrackingConfiguration and get that data in RoomPlan enhancements being done?

it appears that the Metal Debugging interface does not support this method, at least the function hashing algorithm does not have a pattern for it in the symbol dictionary as presented. Where do we get updated C- libraries and functions that sync with the things that are presented in the Demo Kits and Samples that Apple puts in the user domain? Why does this stuff get out into the wild insufficiently tested? It seems thet the demo kits made available to users should be included in the test domain used to verify new code releases. I came from a development environment where the 6 month release cycle involved automated execution of the test suite before it went beta or anywhere else.

The Dynamic library build for the Metal Library fails when built from the downloaded copy. It uses the name of the download as the directory name which has spaces and does not give a syntactically correct file name. Renaming the folder in which the build files reside seems to resolve that problem. Then the header files for the Dynamic library get an access denied error when trying to compile. Why are these demos released with such trivial problems? Surely someone has tried to run it previously and the demo should have been fixed or the short Readme should have been updated with instructions on how to set it up.
