The bug report information is here: FB12279185 (os_log fails to display in Xcode 15's console when an argument is private and instead displays nothing, which is misleading)

Ah yes. That makes a lot more sense. I did finally discover the privacy tag in the documentation, but you’re right it’s pretty misleading not to see that marker. I’ll file a report as soon as I can. By the way, is there no way to set the default to public? I just wanted to replace 100s of printfs with os_log to take advantage of the new Xcode 15 console features. I was going to do a hack solution in which I preprocessed strings and replaced %s with %{public}s, #define MY_LOG(fmt_, …) \ os_log_info(OS_LOG_DEFAULT, gen_public_fmt(fmt_), __VA_ARGS__) but os_log asserts on non-constant format strings.

WebXR will be available behind an experimental flag, so they’re working on it.

There’s some new functionality to help with animation, it seems: CAMetalDisplayLink

I’m getting the feeling that OffscreenCanvas is incomplete and has never been exposed. Maybe the release notes serve only to tell us about the implementation progress.

I see it’s in multiple places in the Safari technology preview release notes, but yes, I cannot access Offscreen Canvas from the window. Does anyone know how to access it, if it’s even possible?

Apparently it's been resolved in 13.2: " Project Navigator Resolved Issues Xcode performance is no longer affected when source code displays several warnings and errors. (84533671) " Of course we have to try it. It's not necessarily entirely fixed.

Has anyone received replies regarding their bug reports? For such a big issue, it is taking a very long time to get feedback.

Is there a way to build to ios 15 and macOS 12 using Xcode 12? I am delaying upgrading due to this. I think the answer is “no,” so I am stranded because my large project is impossible to edit realistically. How can can an issue like this get past v .0?

Has anyone filed a bug report?
