I also verified from the File information that the properties of the file look reasonable

Yes it did. I chased the directory chain and found the bundle file that is being claimed as not present by the following lines Unable to create bundle at URL (file:///System/Library/CoreServices/SystemVersion.bundle): does not exist or not a directory (0) Unable to create bundle at URL (file:///System/Library/CoreServices/SystemVersion.bundle): does not exist or not a directory (0) Unable to create bundle at URL (file:///System/Library/CoreServices/SystemVersion.bundle): does not exist or not a directory (0). When I finally did find the bundle file, I looked into the contents of the package and it looked reasonable from what I had seen in other packages. Why is that message being presented by Xcode if the file exists? Is Xcode supposed to be running in some kind of privileged state on the Mac mini machine? Please explain how those privileges work.

DTS Engineer, how do. you "do less work" when the default minimum is already being done. I had a number of debugging displays of data structures in motion. Turning off the displays was not effective in reducing the work enough. My suspicion is that the. delegate queue is being delayed by the activities of other delegates for class processing.

MarnixArnold, When this happens do you get a "SessionInterrupted" event reported? What is the reason for the interruption when you get the "Ended" event? I am seeing a possible linkage between the two

I tried cutting it back by commenting out all of my debug prints that I had. I still had errors. I moved up to IOS18 as recommended by an Apple support person to see if I could get more memory allocated. Then I ran afoul of the dreaded sandbox requirement that is being enforced. I am also getting errors from the IMU that say the data flow was less than normal and the tone of the message indicates it could be a hardware or delegate issue. Through what delegate is IMU data delivered?

This message is likely not "noise".Actually I would think that finding a resource identifying the current execution environment might be quite useful to identify services and resources that might be needed. Later in the initialization there are messages about use of the "Sandbox" settings of the application which had not shown up until the move up to the latest Mac and IOS betas. Errors I am seeing later in the execution of my modifications to RoomPlan seem to be tied to warning messages of this type for the purpose of resource usage

interesting. comments. I have 9GB of free memory and the program is just starting to execute when I get the messages in the log The memory in use never gets above 1GB and often I s sitting at 600MB in use when the messages start coming out.

Not the best solution but I will try it out

I FINALLY tracked. the cause of this down to residual garbage left by PRIOR executions that do not get cleaned up on termination or restart. I went into the Project Data model settings and set the project to use the Data Model Compiler (MOMC) to create the data model and it cleared out the residual data from prior executions. I am wondering why that possibility was not proffered by the engineers at Apple as a solution. I am also wondering why the execution of a tool and the "clean" of the product files does not clean the data state on the execution platform to an initial state BEFORE execution. Leads me to believe someone out there is not paying attention. BTW this also points out that demo packages from WWDC should not be trusted to be completely reliable or properly set up to execute in a non purified environement "Caveat Emptor" comes to mind.

It would really be.helpful if the source code for AVPointCloudData.m was available so we could see a context and potentially address this

I am mildly curious as to why the key terms in the message cannot be found in a search of the Developer Documentation at the very least. Given the fact that the similarities to Linux are touted often, why is there not a permuted index available of terms found in diagnostic messages for the purpose of diagnosis? the environment I am used to, developers were not allowed to put in messages that did not include a recommended remedy in some product documentation so a user does not feel stranded when looking up an obscure or arcane diagnostic like the one we have here. Telling the User the line of code and relevant labels seems rather rude and elitist if you don't give us access to the means to correct the error. The diagnostic does not even contain eh name of the file containing the data in error or the index of the record in error. Not good form....

I am curious where to find the code where the message originates. If it is serious there has to be a way to remedy it if it is not serious, there should be a way to turn off the noise to prevent management from seeing the message and demanding it be fixed.

Thank you for your response eskimo! The only thing is that when I reorder the protocols it works better and I don't get a failed screen display (all black) and no consistently well behaved screen traffic from the room scan. reordering there protocol list to the way It originally was presented made a significant difference. A message cannot be sent to ALL of the protocols at once so there has to be an order in which the protocols see the message pass through them individually and severally. To have the message pass through all in parallel could result in threadsafe issues. BTW I don't work in C#, only C and C++ preferably the Gnu varieties

Sensor Attachment For ARKit Structure

My concern is the question whether the sensor is connected through a bus structure (similar to a PCIe crossbar type switch chip) that if one devices is reset some developers take the short cut by resetting the switch chip instead of resetting individual ports. see attached file for more info
