Would you by any chance consider TestFlight to distribute UTM? iSH (a usermode Linux "terminal" emulator) has been for quite some time, and I can't see why you shouldn't be able to.

  Ah sorry, my bad, I skipped over that. Here's an idea - you could start a "fundraising" of sorts and if you get enough you could purchase a developer profile to publish to TestFlight.

    You can’t purchase such a profile. Apple doesn’t ever give them out.

      I thought this would be part of their $99/year subscription, well that's unfortunate. Thanks again for your project.

    The problem here is not that they can't obtain a development certificate. The problem is that you cannot use a development certificate to distribute an app on TestFlight or the App Store to other people. There are two types of certificate – development certificates, which allow get-task-allow for debugging purposes and can be installed directly to a device; and distribution certificates, which do not allow get-task-allow and can be distributed through ad-hoc means, Test Flight, or the App Store. If this app requires get-task-allow, then it needs to be signed with a development certificate to run. If it's signed with a development certificate, then it can't be distributed to other people.

iSH works differently. It’s not running “Linux” and it isn’t virtualizing hardware either. Anything you run has to be compiled already and the syscalls are emulated, there is no Linux kernel in iSH.

  I said it was a 'usermode Linux "terminal" emulator', never said it was a VM or anything like that. IIRC the dev said he also wasn't allowed to publish it to the App Store and I assume it falls under the same catagory of "not allowed" in Apple's eyes as UTM would've had.

      Actually, someone compiled it, added ads, and put it on the App Store. Not sure if it is still there, but it got through approval.

        Oh, that happens all the time. The real test is when the official app gets approved and stays on the App Store.

  iSH actually uses a semi-JIT to emulate an x86 CPU — it doesn't run ARM64 code. It basically creates an arrray of function pointers to snippets of pre-translated code. It's not a full JIT like UTM, but it's an interesting workaround for iOS' restrictions.
