Right, but the QEMU project is also simply loading X86 (or other) assembly code and interpreting it in a virtual machine... unless I misunderstand this project and it does something more sophisticated.

> the limitation of having half the screen showing the executed code

I'm not aware of this limitation, could the QEMU port use this to show the ASM that's being executed to get around this?

IDK about virtual machines and why this isnt allowed. But related is how this app works that is a c compiler for iOS and is in the app store: https://www.reddit.com/r/iOSProgramming/comments/dr5bxi/app_...

It basically does the same thing Swift Playgrounds does where is compiles to LLVM machine code and runs it will LLVM compiled for iOS. And it is on the app store so IDK the rules at all apparently and why QEMU wouldnt be allowed.

The rules apparently (since last year or so) are that you can interpret arbitrary code as long as the code in question not only legally but in practice meets the definition of the zeroth FSF's rule (notice that the “executables” on the FS image distributed with SeeLess are LLVM IR assembly text files, which is probably the reason why the thing is so damn huge)

Swift Playgrounds compiles to native code and loads it with Apple-private entitlements.

the largest difference is that Expo uses JavaScriptCore, a framework provided by apple for use by any application that wishes to execute javascript code. Since it is their own interpreter it is fine.
