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?

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

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.

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

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

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. Reference is 2024-06-18 16:03:36.871062-0500 RoomPlanExampleApp[860:159744] [loading] Unable to create bundle at URL (file:///System/Library/CoreServices/SystemVersion.bundle): does not exist or not a directory (0)

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. "2024-06-20 19:27:00.669334-0500 RoomPlanExampleApp[902:299709] [Technique] ARWorldTrackingTechnique &lt;0x104bf6d80&gt;: 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].

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.
