Thanks for the response, Eskimo,
Agree it may not be a bug the idea of public vs private is illuminating. However, it would be beneficial to document what OSLogPreference affects. Its behavior between Xcode, Console, the log utility, and syslogs pulled from cfgutil is surprisingly different. Unless I'm missing some documentation, the only way to figure this out is through empirical testing. In the ideal, this would be consistent, but if nothing else some addition to the man pages could be really useful.
I also noticed you responded to a post I made four years ago. I appreciate your support in the forums!
I have a renewed interest in leveraging structured logging for my team with the introduction of Xcode 15. I'm actually finding I have a lot of feature requests to make. I'll write those up later this week with my findings and post them here.

One more update, I tried running sudo log collect --last 15m --device-name 'X. This does seem to respect the log preferences...
Actually, OSLogPreference isn't behaving as expected when on the device either.
From what I can tell Level in OSLogPreference only seems to affect the logs if they are labeled "Off". Default, Info, and debug do not seem to have the desired effect.
So in a fresh project I added these log lines:
let offLog = Logger(subsystem: sub, category: "offLog")
let debugLog = Logger(subsystem: sub, category: "debugLog")
let infoLog = Logger(subsystem: sub, category: "infoLog")
let defaultLog = Logger(subsystem: sub, category: "defaultLog")
let unsetLog = Logger(subsystem: sub, category: "unsetLog")
offLog.debug("1: offLog.debug")
debugLog.debug("2: debugLog.debug")
infoLog.debug("3: infoLog.debug")
defaultLog.debug("4: defaultLog.debug")
unsetLog.debug("5: unsetLog.debug")
offLog.info("1: offLog.info")
debugLog.info("2: debugLog.info")
infoLog.info("3: infoLog.info")
defaultLog.info("4: defaultLog.info")
unsetLog.info("5: unsetLog.info")
offLog.notice("1: offLog.notice")
debugLog.notice("2: debugLog.notice")
infoLog.notice("3: infoLog.notice")
defaultLog.notice("4: defaultLog.notice")
unsetLog.notice("5: unsetLog.notice")
offLog.error("1: offLog.error")
debugLog.error("2: debugLog.error")
infoLog.error("3: infoLog.error")
defaultLog.error("4: defaultLog.error")
unsetLog.error("5: unsetLog.error")
With this pList
Xcode always outputs all of the logs. and console only removes the logs from "offLog"
Xcode:
Console
Seems like a bug?
