    Note that, unlike Corellium, this isn't about emulating an iPhone. Apple is providing an iOS kernel for Virtualization.framework in PCC/cloudOS images and this project pairs it with the iOS user-space and patches to make everything run. Applications can very easily tell it apart from the real thing.

        The handle is publicly[1] tied to a South Korean security researcher, and there’s no evidence that it refers to white supremacy.

          Even if this person is South Korean and didn’t just adopt a pseudonym as a fig leaf, that’s not an affirmative defense against being a white supremacist.

          The evidence is prima facie, it’s right there in the name. “14” is a famous-enough racist dog whistle it’s got a Wikipedia page, and when paired with “white forever” it ceases to be a dog whistle.

            You are expecting everyone to be as aware of these issues as you are. I don't think white supremacy has as large of a share of the mindspace in south korea as you think - not every issue (even if it has a wikipedia page!) is burned into everyone's mind across the globe. But I am happy to hear that every time you pick a username, you make sure it is free of dog whistles in all cultures and that the letters and numbers cannot be picked out or rearranged in a way that hints at one.

    > during iOS setup, don't pick Japan or the EU as your region (extra regulatory checks the VM can't satisfy)

    I'm curious what are these checks

    • benoau 16 hours ago
      It will be to prevent access to third-party app stores as both the EU and Japan legislated they must be allowed.

      > In a support document about alternative app marketplaces in the EU, Apple explained that “device eligibility for alternative app marketplaces is determined using on-device processing with only an indicator of eligibility sent to Apple.” In practice, iOS users in the EU who want to install alternative marketplaces will need to set the country or region of their Apple ID to an eligible country or region. Moreover, they will also need to be physically located in supported EU countries.

      > In the case iOS users in the EU leave eligible regions, Apple will offer a “grace period” until apps downloaded from alternative app stores can no longer be updated. “If you’re gone for too long, you’ll lose access to some features, including installing new alternative app marketplaces. Apps you installed from alternative app marketplaces will continue to function, but they can’t be updated by the marketplace you downloaded it from,” the company explained.

        Wait so a third party app-store is allowed in the EU? I was not aware these even existed...
        • xkgt 14 hours ago
          It is wild that Apple finds it cheaper to build and maintain different App store behaviors than to simplify and make alt app stores available in all markets. Other governments/markets don't care?
          • benoau 14 hours ago
            It's a very slow process, first there is investigations, then legislation, then enactment, then enforcement which is separately a very slow process. It requires a lot of willpower to get and keep the ball rolling and in fact nobody has even achieved the full extent of what they require yet! The EU may still be years away from meaningful compliance, Japan has only taken baby steps forming a new bureau just to enforce compliance of two companies widely accused of malicious compliance.

            And then there is additional discouragement and pressure in the form of sanction and trade deal threats for regulating American tech platforms.

            As someone using AltStore PAL to install some third-party apps that would never be allowed on the App Store (such as emulators and manga readers), I heavily disagree.
    • astafrig 15 hours ago
      In addition to the third-party installation capability mentioned by siblings, Japan also has a regional capability for reassigning the side button to a third-party voice assistant (`com.apple.developer.side-button-access.allow`).
      • ajaieadad9 11 hours ago
        I also found out the Chinese version has the ability to block an app for accessing both mobile data and Wifi/WLAN data.

        All other versions only allow denying mobile data to an app, not Wifi.

        I really wish there was a way to enable this feature.

        • tancop 7 hours ago
          Xiaomi phones support it in all regions. Think about it, a company famous for putting ads in system apps has the feature but "privacy conscious" Apple literally put in extra work to disable it everywhere it's not legally required.
          • close04 2 hours ago
            That iOS toggle isn’t about privacy but about mobile data usage. Users with data caps can limit the usage for non-essential or high data volume apps (streaming or cloud storage apps come to mind).
            • mthoms 2 hours ago
              I think the point is that the code path to deny network access for arbitrary apps exists (at least according to this comment):

              > I also found out the Chinese version has the ability to block an app for accessing both mobile data and Wifi/WLAN data.

              Yet Apple is choosing not to enable it for everyone. It seems like it would be an easy and obvious privacy win, no?

        • TalkingCodeMonk 9 hours ago
          This is a strong indicator that Apple's privacy claims are little more than a virtue signal. Network sandboxing an app is arguably the strongest privacy protection measure possible.

        That would surprise me. I don't recall having to change my iPhone's region after moving to Japan. Transport IC cards in Apple Pay have "just worked".

        I am vaguely aware that some phone manufacturers silently remove certain NFC hardware (or disable some driver) in order to avoid paying Sony patent fees. Apple doesn't seem to do that, though.

        • robert-boehnke 9 hours ago
          There were iPhones with Japan-specific hardware for transit cards in the past but as of a couple years ago, all iPhones have been compatible.

      I'm tired of Apple and its stupid rules, and its arrogant assumption that it is better than a democracy.
      • close04 2 hours ago
        Companies have never been “democracies”. Most companies are more like dictatorships internally (for employees) and past a certain size also externally (for customers). Everything is dictated by a small group of leaders and shareholders not chosen by either employees or customers.

        If you really want to imagine them like democracies, you are voting with your wallet. Maybe you’re just in the minority.

        • amelius 40 minutes ago
          Nobody said companies _are_ democracies ... you're reading something that is not there.

          The point is that Apple thinks it can somehow bend the rules of the EU that were established democratically. As if users are better off with Apple's rules.

  • hamandcheese 17 hours ago
    This seams neat, but I'm not sure I understand the purpose/difference between this and using the iOS simulator.
    • restes 17 hours ago
      The iOS Simulator consists of (some of) the userspace components of iOS compiled to run on macOS. This would be a full iPhone image running as-is via virtualization.
      • RussianCow 16 hours ago
        That explains the difference, but what's the purpose?
        • whynotmaybe 15 hours ago
          The simulator doesn't have a camera. The android emulator allows to configure the camera and use a picture, it's very handy to test your qr/barcode reader without needing to use a physical device. Maybe this also allows to use an image as camera?
        • landr0id 12 hours ago
          It's useful for security research since you can do kernel debugging and inspection of the device not possible in the simulator.

          As others pointed out it's also useful for e.g. click/spam farms which need a "real" iPhone.

        • a012 16 hours ago

              I have had instances where the app runs fine on the simulator but crashes on the device. This might solve that.
            • refulgentis 16 hours ago
              Running on ported userspace components, with a shim, isn't the same as running on the OS in itself.

              That really matters, sometimes.

              But not the vast majority of the time.

              • RussianCow 15 hours ago
                Can you give some examples of where it matters? I'm genuinely curious.
                • afavour 8 hours ago
                  It’s been years but I ran into a problem with a notification extension years ago. Worked fine on simulator, not on device. Turned out it was because I was using a HEIF image and (I think) the on-device extension was trying to use hardware decoding and didn’t have access to it. Meanwhile the simulator had no such sandboxing restrictions.

                  The difference doesn’t matter until it does, and then it’s infuriating to work out what’s going on.

    • dagmx 13 hours ago
      The simulator is a different SDK target than iOS itself.

      You have to compile completely independently for it, and depending on your dependencies they may not compile for the simulator.

      Additionally the simulator runs a really ancient and feature restricted version of Metal. That means you can’t test a lot of graphical things that the hardware actually supports. I’m not sure if this supports GPU passthrough but the macOS VMs do, so that alone would be a huge improvement if possible.

    • ChrisMarshallNY 15 hours ago
      The simulator is a completely different OS. It may even still be using Intel.

      I always figured that Apple never set up a true emulator (like what Android does), because they didn't want people exploring their OS with a debugger.

      • kridsdale1 15 hours ago
        Incorrect. The iOS simulator is and always has been, simply iOS frameworks running fully natively on macOS. It’s best to think of it as an alternative window managers but the apps are native Mac processes. They can be seen and debugged via the terminal using top and ps and lldb alongside all other processes. They just present gui via the Simulator Mac app container.

        They do not live in a VM and are certainly not emulated at an instruction set level. They are Mac apps.

        • ChrisMarshallNY 15 hours ago
          Ah. That makes sense.

          I would think that "Mac apps," means that they are, actually, a different OS (I actually already knew that, which was why I said what I said. The Intel thing was a spitball).

          But one of the few joys geeks get, these days, is telling other geeks they are wrong, so I feel as if I’ve done my bit to make this a happier place.

    • vlovich123 18 hours ago
      If you’re talking about the simulator, no. That doesn’t virtualize - it literally just runs it locally on your machine. Less RAM overhead and CPU since it uses your normal instruction set and doesn’t run a separate kernel and userspace.
      • valleyer 18 hours ago
        At least historically, it actually did run its own entire userspace, including daemons (all the way to launchd, IIRC), etc. All compiled for Intel, back in the day. Shared the kernel though.

        Many of the nominally shared system pieces between Mac and iPhone (like Foundation) actually had many subtle compile-time differences.

    • fredoliveira 8 hours ago
      This is virtualization, so localhost will just be the virtual iphone itself. But you should have some command of how hosts are resolved, so you can always point the browser to the device hosting what you want to test, no?

      Even easier, of course, is just using the iOS simulator included with xcode, which runs on your host computer. There, localhost resolves to your host computer.

Presently, the only way to get free cloud inference is by joining the App Store Small Business Program.
