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.
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.

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.

It's a full x86 emulator.

He didn't, it's just never been tested whether it could be on the store or not.

You can compile binaries on iSH and they'll run on the emulator just as all the other code does.
Compile using what? It’s form of emulation has never been complete enough to run a compiler (heck even interpreters like Python have been very brittle) in my experience as a user since the beginning, so I’m curious what you’ve seen success with.
