does anybody know what this means? I read the first can be something to authorize home sharing but I literally have never used home sharing or anything like that. Can anybody tell me what these are from?

iPhone 12, iOS 16

If you’re not Apple and not an app developer troubleshooting an app, then reading logs and reading telemetry data is not going to be particularly fruitful nor enlightening—that data is typically written to be interpreted by the folks that have access to the source code involved.


As for log readability… Normal and benign messages are routinely use cryptic or ominous wording, for instance.



If you wish to better understand iOS, best acquire and read the volumes of the New OS X Book.



As dor your question…



The former is related to logging:


NAME
rtcreportingd — Diagnostics and Usage Reporting SYNOPSIS
     rtcreportingd

DESCRIPTION
rtcreportingd is a system daemon that collects diagnostics and usage 
telemetry data locally for users that have opted in for reporting.

There are no configuration options to rtcreportingd, and users should 
not run rtcreportingd manually.



The latter looks like there might be a typo in what was posted, or it’s not been particularly discussed before.

Nothing here indicates evidence of having been hacked.


If you’re a target for hacking, you need better advice, and direct access for forensic assistance.


If you want to know how iOS works, the New OS X Book series is a good start. Posting “what’s this?” from analytics and from logs is a slow path to this end goal, particularly given ~none of the messages are documented.


Reading and posting text from analytics reports is ~useless, absent specific targets to search for. There’s way too much data, and iOS is always churning along producing more data. Trying to find needles in haystacks, without knowing what the needles look like nor knowing how many haystacks, nor whether there even are any needles. Lots of,work, not all that much for results.


Check my posting history about iPhone hacking, too. It happens. You’l find I do refer to resources and related documentation on previous iOS hacks, including the work of CitizenLab investigating same. Etc.
