WWDC 2022: What was Announced

Oh more: iMessage edit, undo send, and mark unread! Yes! But still no tapback with any emoji.

Some bit of plumbing that was left out of the presentation about Ventura:

• macOS security gets even stronger with new tools that make the Mac more resistant to attack, including Rapid Security Response that works in between normal updates to easily keep security up to date without a reboot.

One of the biggest complaints about modern macOS is the size of updates. Sometimes, a patch for a single vulnerability will be multiple gigabytes. It looks like Apple is working to reduce the necessity for those gigantic downloads, making it so that a Mac won't always need a reboot.

iOS gets Rapid Security Response too, IIRC. Nice.

I added “unannounced” to the wiki post at the top of this thread for things I’m finding that were not announced. Like, now you can see your wifi passwords in the settings app

Yep. It’s mentioned in the wiki post at the top of this thread

Oh finally!

iOS 16 Will Let You Lock Your Hidden and Recently Deleted Photos Albums

Apple is adding the ability for users to lock their Hidden and Recently Deleted albums on iOS 16, requiring user authentication through Touch ID or...

Swap on iOS and iPadOS will be a game changer.

Not just for Apple but will clearly differentiate the Apple devices from competitor android machines (in terms of capability) that use cheaper crappier flash or even run the bulk of their content from micro SD.

Question: is there swap on iOS? Or just iPadOS?

To be fair I’ve only read the summaries and haven’t watched the keynote yet (it would have started around 1am here)

I don’t think they gave an answer, but the discussion of swap came during the iPad portion. I would not be surprised if there is no swap yet on iPhone. That could even be something that differentiates iPhone Pro vs. iPhone in the future models.

Not much to go on for M2, but the faster memory bandwidth and ability to have more physical memory is most interesting to me. Certainly must be avalanche and blizzard. No ray tracing in the GPUs is notable, but that seems like something that would come in the 3nm node, I guess - physical die Area must be at a premium since they are still at 5nm, and ray tracing isn’t small, is my understanding.

What dictates the amount of RAM that a CPU can address? I find it somewhat counterintuitive that the M2 can't address, for example, 32GB of RAM. I get why having more bandwidth is difficult, but why is supporting more RAM capacity difficult? I know that a couple decades ago computers had much higher headrooms (i.e. the PowerMac G3, which shipped with 64MB standard but could go up to 1024MB), but nowadays a lot of CPUs seem to be much more limited in the RAM capacity they support, compared to the 'standard' or average configuration.

Could be a number of factors. Address bits is one (of course each additional address bit doubles the amount of addressable RAM). The size of structures like TLBs and caches (more so the TLBs than the caches - caches just get less efficient at a given size if RAM increases). Etc. Could also be physical factors - power, package area, etc.

Is it just me or does Standard and More Space look the same?

My text sure got a lot smaller in “more space.”

Things like buttons stayed the same size, which makes sense since they need to be tap targets.

Oh f*ck. M1 iPads only.

 

[Cmaier]

Haven’t found a way to edit the Lock Screen on iPad. Maybe that’s just an iPhone thing? Or maybe simply not implemented yet.

Yeah, i get the feeling a lot of these things will be only M1.

I don't know if they mentioned it on the keynote (I may have missed it), but on the SOTU they presented Swift Charts, which is a super powerful API for charts. I had missed something like that (1st party) for years.
